i dont even know how to thank you for all these very helpful videos. i am a biomedical sciences major and i use your videos to help me understand my biopsychology class ! you are amazing
I'm sure this is asked often, but is there a way I could see a works cited for these videos? I dont know if I should be embarrassed or not, but I'm using some of these videos as part of my studies for my Masters.
I have a question : so when Olivia got anosmia, does her brain still react of the chemicals from her food? Like will they still release the proper enzymes to the food she eats?
This episode makes me so happy but also really frustrates me at the same time. Although I'm glad you've really helped to raise awareness of anosmia in this video you've also only spoken about it in a negative way. I'm congenitally anosmic and like most others I've met through making videos about anosmia, it doesn't bother me because I've never known anything else. Aquired anosmia as a very different experience but on the rare occasion anosmia is mentioned it's always from this angle. I don't really know what the solution is to this problem, since it's the only way to make the seriousness of anosmia clear. It's just rather upsetting when your impairment/disability is only talked about negatively. That being said I am really happy that you talked about anosmia on crash course, that's so many more people who are aware of the condition and if the comments on my videos are anything to go by, quite a few anosmic people who just learned the name for their condition. So thanks :)
joolzzenda yeah, I was also born with anosmia, so my taste buds compensate for food, and it is really just kinda cool. Like I can just grab a skunk, no problem. Anosmia isn't always that bad, but it's nice to bring awareness.
That's actually not true! I've had a disability my entire life and in my case it definitely has its perks! Not saying these outweigh the challenges by any means but there are still positive aspects to it.
thank you so much for the video but as far as i know that the anosmia is temporary according to junqueira`s basic histology book page 345 is that right ?
Is it possible that a small error was made there? Is it that there are 10,000 different chemoreceptors enabling the detection of 40 million different identifiable "smells"? If 40 million receptors only allowed 10,000 smells that would be embarrassingly inefficient.
Hawaiian and Marinara are probably the only kinds of pizza that totally suck. If there's two things you should never mix with cheese, fruit and seafood are pretty high on the list...
kryptospuridium137 Hawaiian pizza was the first and only kind of pizza I was willing to try as a kid. Now I like almost all pizzas, including Hawaiian. I can see why you may not like it though. Depending on how it's made, sometimes the pineapple is a little out of place. To be fair though, I think it was mostly the cheese that won me over as a kid, and a plain cheese pizza was a little boring. I would happily eat a plate of cheese for breakfast, lunch and dinner if I could back then.
Iv got it due to polyps and i totally get this! "Oooh smell this!" "How about pi** off Karen!"😂😭 I also get "oooh your so lucky!" (Cause i work in care) 🤦♀️

You have saved me and gotten me through BIO202 this semester. I can sit in a lecture for an hour and not understand a word my professor is saying. You can get the same information to me in 10 minutes and I can actually understand what you are saying. Thank you for doing what you do!!
CrashCourse You had such great opportunity to make a joke there! You could've let Hank eat a bite of pizza between each scene and in the end he'd be left with empty hand. Or even more subtle - take different slice of the same pie in each shot suggesting he ate all of it.
Great video! Maybe I can contribute some further insight as a layman. I haven't been able to smell for over twenty years, and there are many benefits. The primary benefit is not being disgusted by pretty much anything, so I never get nauseous and I am immune to those odors that would cause ordinary people to gag etc. Vomit, feces, farts, decay, rotting food or animals cannot be smelled and therefore do not bother me. I could wade through a river of raw sewage and not be affected by the smell (not that I would lol). Getting the flu is not like it was when I could smell - it is more like a bad cold with weakness and fever, and none of the nausea and reaction to smells during a flu occur anymore. I can also interact with people without the normal distractions of body odor, bad breath, cigarette smoke or too much perfume - thus it is more pleasant and easier to engage with people, as simply people and not be burdened or offended with their smell (offensive or not). Living with, or being around people is much easier when you cannot smell. Perhaps one's impression of another is clearer, and unbiased, when the complexity of smell is removed from the equation. One could say that it was impaired too, but I don't see it that way. Another benefit is that I am not obsessed with eating all the time or "living to eat" - so weight gain and over-eating is never a problem. I do enjoy food though, because I can taste just fine. I should also point out, that the actual sense of taste (not smell), is now somehow enhanced for me. Since the input is purely taste, I can pickup subtle nuance in the pure tastes of food without the interference of smell. Another benefit is that I pretty much like every food and I don't have any aversions that are caused by powerful smells. I can't think of anything that I won't eat, sans the exotic things like grubs and insects - but I am sure I could get used to them if I lived in those parts of the world where they are the normal cuisine. I realized after many years, that when people talk about taste, most of the time they are really referring to smell. For example, saying that beets taste like dirt. Well that's not really true, it's just an expression of what people think is taste, but it is primarily smell and texture. In fact, it seems to me, that anytime someone protests certain foods, it is never about the taste, but always about the look, smell and texture. Powerful chemicals, smoke and other things like that - I cannot smell, but I can "feel" them in my nose as a sensation of burning or my eyes will react - So I am not blind to hazardous environments. I can certainly remember what things smell like, so there is a reference - and I should be clear that there are times when I wish I could smell again. Smells that I miss, like freshly cut grass, gasoline, freshly washed laundry, coffee, wine, bakeries and gourmet kitchens etc. - but in the end it is not all that bad, and one gets used to it and finds the positives to be rewarding.
As an 8th grade teacher, Thank you! as a nerd, Thank you! I love that the kids I teach can see senses are far more than a standard health text book shows. I also enjoy the exposure to upper level nomenclature. Thank you!
Hey Hank! This has been one of my favorite episodes so far in this lesson series, and not only because I happen to suffer from Anosmia myself. It was enlightening to look at the senses that I personally cannot experience. I have been like this since birth, or at least as long as I can remember, and I'm just lucky enough to not have complete taste loss. Thanks for making this!
joe mastropiero Me too. Except I lost mine when I banged my head. Of course it would be Hank to be the first person I ever hear talk about it sensibly... a lot of people tell me I'm lucky when I say I can't smell which ridiculous and very annoying.
joe mastropiero I am anosmic as well. The best information I ever received from a doctor was that there's not much information on it, because there's not much money in it.
Jason Basgall Well you did better than me at the doctors at least... I was having problems eating as a results of it but they didn't believe that the problem was physical and instead diagnosed me with anorexia and sent me to therapy. Cause you know how teenage girls are all crazy.
It's so fast Mr. Hank!!! Awesome channel! It was so fast that taking down notes felt like playing some hardcore game! I hope that one day you'll provide us with a reading material (preferably pdfs) so that I wont have to pause/resume pause/resume the entire video to take down notes and absorb some concepts. Sorry for not as being as smart as the others. A short quiz would be nice too!
I honestly love this channel so much. My teachers can be so boring and when I do ask in-depth questions, most of them tell me that it's "not in the lesson plan" and/or that I should research it on my own time. I usually forget or I never have the time BUT with the amount of information covered in just one video is impressively comprehensive and easy to access. Plus, it isn't boring to listen to :) I love the app and keep doing what you're doing!
My wife had (and has) the exact same story as Olivia. It's amazing how much we rely on smell and don't realize. For Tammy, after several weeks, we did a blind taste/smell test with Lifesavers and candles to prove our theory.

As an artist too i have a lot of respect for the whole team, i don't even get their process and it makes it even better. I love all the little touches here and there, the easter eggs and the hidden gems :D
Just went through two pages of comments. It was only then I realized I was taking every opportunity to like, and post comments in agreement with, every comment declaring how gross pineapple is. I have a instinctive visceral reaction to pineapple in all its forms, whether it be pizza form or whole fruit form. Some people just don't like pineapple, I guess.
coming from someone who is Sitting in a college lecture basically a mental and emotional wreck from not understanding anything, watching these really help me to learn stuff for my tests and also make me laugh and provide helpful real life examples that i can use to help understand!
there are only 3: Cranial nerves 7 (goes to the front 2/3 of the tongue), 9 (goes to the back 1/3 of the tongue), and 10 (goes to the back of your throat).
I think I'll be looking forward to this season's outtakes a lot more then usual, if only to see the ones from this particular episode. Seriously, so much willpower involved...!
I guess they eventually get mixed up with saliva and we ingest it. That maybe why sometimes we feel tast of the food when we swallow saliva right after eating something
Hello, CrashCourse. Just wondering: if each olfactory neuron has receptors for just one kind of smell, does that mean people who super smell like my mum have a lower threshold for action potentials to happen? or does it mean they have more olfactory neurons than most people?
I usually love the Crashcourse series. This one, however, gets TASTE versus FLAVOR mixed up. Smell happens due to the nose. Taste happens due to the tongue. Flavor requires both smell and taste. So for example, a person with anosmia has no smell, has normal taste (can detect all taste qualities), but cannot detect the flavor.
MK Mailler Because usually other senses kick in for dangerous situations. I have anosmia (from birth) and although I wouldn't smell smoke in my apartment, my smoke alarms would rattle my ears and I'd know the danger that way. Or perhaps I walked into the kitchen and saw with my eyes the haziness from smoke and then knew I was burning something in the oven. For spoiled milk I check the expiration dates all the time and I can taste slightly souring milk pretty well. There are very few situations where a danger can get me that could only be detected by smell so the disadvantage I have really isn't disabling or severely inhibiting me to function in the world.
Constant mild nuisance but not debilitating, I can see that. I suppose I need to work on my workarounds and seek out more alternatives in how I do things. The spoiled food aspect has to be one of the largest problems I've faced.
You sound like a recent anosmiac. Thus I cannot offer advice on "workarounds" as I've never smelled before so I've never relied on that sense for things. I suggest checking out the /r/anosmia subreddit on Reddit for better advice on workarounds.
MK Mailler as an asnomic from age 10 due to a complcated mess of sinus problem.it's simply something you get use to. I had a few apptie issues when it first happend, but I just started eating weird things that I had no idea how they "should" taste, and just worked out from there. I supose if I pushed hard enough, I could get a gas leak detector in my house but it's just not worth the effort
A good way to demonstrate this is to close your eyes, grab a candy like a starburst or skittle and try and guess what flavor/color it is. You'll taste a sweet, fruity flavor but you won't be able to pinpoint what it is. You'll be sure its a red starburst and then be shocked to open your eyes and find that its yellow, the worst one.
Krishna I'm afraid I'm only starting my module on that this week so can't give you a very good answer! I studied depression at college which was quite straight forward, I imagine maybe a personality disorder or something uncommon would be more difficult x
I don't know if anyone of you also has the same thing: I can smell an object without actually smelling it. I mean, when Hank was smelling the pizza, I also kinda... smelled the ham, cheese and so on. Not that it always happens, but I just have to focus and imagine how something smells and it's like my brain tells me that it smells the object even without it being there. Is it that my brain remembers some smells and just recalls the sensual memories of how the objects smell? It's pretty weird and I hope I described it as well as I can.
I could be wrong, but I'm pretty sure receptor cells express a single odorant receptor and converge onto single glomeruli in the olfactory bulb. So those colored receptors shouldn't all go to the same glomeruli.
Salomon Flamenco When I saw that the new CC about intellectual property had the word "philosophy" in the title, I imagined you getting a wave of excitement before dying a bit inside. Please tell me that happened.
CrashCourse Both in the video summary and in the end of video review it says that gustation depends on four cranial nerves, but at 9:05 only 3 of them are enumerated (which is the correct number).
I've been anosmic since birth, and this video has taught me more than any doctor ever has. Thank you Do you have any resources where I can learn more about the psychological and emotional effects of anosmia?
I like how parts of our body, like the Glomerulus, take their names from Latin words for something obvious. I can just imagine what that person is thinking when they're naming a part that hasn't been named yet. "mmmm... this looks like a ball of yarn! but I can't name it Ballofyarn.. What's a word that sounds more cool and serious?? Let me fetch my Latin vocabulary book." sounds like me in english class as I write my essays.
I love your episodes i swear this helps me alot with psychology ❤️❤️❤️❤️ i just wish u didnt talk so fast 😂 but u r a great teacher and very entertaining
My kids and I really love this channel and we are super grateful for all those making the videos, it's such a nice way to learn opposed to a textbook where we can't be sure we are pronouncing the words correctly.
I have been waiting for this video for SO LONG!!!! I lost my sense of smell /taste when I was nine and no one understands just what that means in day to day life. Thank you for making this video!
I recently suffered the exact situation described in the video. I was cycling to work when I was struck by a taxi. After a few days in hospital suffering a bleed on the brain, fractured skull and heavy concussion, I suddenly found that I couldn't smell anything but what seems to be gas, and nothing has changed for almost five months now. This has not only spoiled every meal and glass of beer consumed since, but also my work as a bartender/waiter. I have to impart my beer and food knowledge to customers when asked for advice and to pair food and drink. I can't recognise subtleties in hops any more, and find myself seeking out extremes in bitter, hoppy and sour beers simply to taste a lot of something. Question: is there anything that can be done to 'retrain' by olfactory system into recognising smells again?
In this video, I learned that anosmia can be caused not only by head trauma, but also through respiratory infections and aging. I also learned that each olfactory neuron has receptors for only one specific type of molecule, or smell. These signals are then sent down the axons where several axons meet up at a glomerulus. At the glomerulus, mortal cells interpret the sensory information and transfer it to the brain. The information then travels to the frontal lobe and limbic system, hypothalamus and amygdala where it triggers a powerful emotional memory. Lastly, I learned that taste is almost 80% smell, and that when you can’t smell during a cold, it becomes hard to distinguish between different types of certain flavors (such as salty, sweet, etc.).
Good debunking, but the cranial nerves innervate tongue in a little bit different regions, and although all tastes can be detected over the entire surface of the tongue, different regions have different thresholds for various taste This differentiation was also shown by fMRI scan, showing different local activation on the insular cortex in the response to each of the tastes encoded by taste receptors.
I’m here because covid took away my sense of smell
i dont even know how to thank you for all these very helpful videos. i am a biomedical sciences major and i use your videos to help me understand my biopsychology class ! you are amazing
1:45
BABIES CAN DO THAT!
dayum, their good
This is such a good way of learning
I'm sure this is asked often, but is there a way I could see a works cited for these videos? I dont know if I should be embarrassed or not, but I'm using some of these videos as part of my studies for my Masters.
simple yet very informative.
thanks again.
hangry hank has me cracking up bahaha
i took a online nursing quize and i actually am learning :D
I have a question : so when Olivia got anosmia, does her brain still react of the chemicals from her food? Like will they still release the proper enzymes to the food she eats?
I literally just had an exam on this today! dangit!
Hawaian pizza!? Now thats what I call anosmia.
This episode makes me so happy but also really frustrates me at the same time. Although I'm glad you've really helped to raise awareness of anosmia in this video you've also only spoken about it in a negative way. I'm congenitally anosmic and like most others I've met through making videos about anosmia, it doesn't bother me because I've never known anything else. Aquired anosmia as a very different experience but on the rare occasion anosmia is mentioned it's always from this angle. I don't really know what the solution is to this problem, since it's the only way to make the seriousness of anosmia clear. It's just rather upsetting when your impairment/disability is only talked about negatively.
That being said I am really happy that you talked about anosmia on crash course, that's so many more people who are aware of the condition and if the comments on my videos are anything to go by, quite a few anosmic people who just learned the name for their condition. So thanks :)
joolzzenda yeah, I was also born with anosmia, so my taste buds compensate for food, and it is really just kinda cool. Like I can just grab a skunk, no problem. Anosmia isn't always that bad, but it's nice to bring awareness.
joolzzenda Well that's probably because there's nothing positive about having a disability ):
i think its gotta be cool meaning you can either eat broccli or pizza and can imagine having same taste
So you're still able to taste food, correct?
That's actually not true! I've had a disability my entire life and in my case it definitely has its perks! Not saying these outweigh the challenges by any means but there are still positive aspects to it.
thank you so much for the video
but as far as i know that the anosmia is temporary
according to junqueira`s basic histology book page 345
is that right ?
Is it possible that a small error was made there? Is it that there are 10,000 different chemoreceptors enabling the detection of 40 million different identifiable "smells"? If 40 million receptors only allowed 10,000 smells that would be embarrassingly inefficient.
Hawaiian and Marinara are probably the only kinds of pizza that totally suck.
If there's two things you should never mix with cheese, fruit and seafood are pretty high on the list...
Aaand why should I not eat Hawaiian pizza if I wanted to and like it?
kryptospuridium137 As soon as I saw the Hawaiian pizza, I knew there would at least one of you in the comments. :)
Kristian Thomsen You should, but don't make me. Ugh!
kryptospuridium137 Hawaiian pizza was the first and only kind of pizza I was willing to try as a kid. Now I like almost all pizzas, including Hawaiian. I can see why you may not like it though. Depending on how it's made, sometimes the pineapple is a little out of place.

Tomato is a fruit.
hey, in the end where are you, aren't you included in this too?
It would've actually been funny if there was a small bite of the pizza missing after every cut to the animations :)
Lol
I was born with Anosmia. The most annoying part of having anosmia is how much people forget that I can't smell.
The End, Again Definitely. My best friend of 4 years forgot nearly every single day it was really annoying.
I tend to find it hilarious, especially when they have this 'oh shite' face when I inhale dramatically and tell them 'No, nothing'
The End, Again I can’t smell either!!
Iv got it due to polyps and i totally get this! "Oooh smell this!"
"How about pi** off Karen!"😂😭

3 months after recoverd from Covid 19 - still can't smell - who's with me 😭😭😭
Just one week passed but its annoying
Did you got it back
I hv got it back almost 80 percent after 12 days
OSP Vibesy your a life saver this is stressing me
Did you take anything
I'm just glad to see the continued debunking of the stupid shit that was being taught when I was a kid.

I like the word 'umami' so much that after hearing it I started reciting it like a lunatic and completely lost focus for about a minute
wait, so if I where to spend my whole life sniffing a piece of pizza, then sooner or later it will disappear?
Eijirou Kirishima yea but it would take more than your lift time. More like 1 000 000 years
well now i wanna try it...
I temporarily lost my sense of smell for about a week and a half, due to a sinus infection followed by very dry sinuses. Not fun at all.
Now I want pizza :(

Keegan Grant No, but I bet I will from now on!

You made me buy a pizza *****.
a potential market deal for pizza advocacy, found.
Are there 3 or 4 cranial nerves that are involved in taste? Earlier Hanks mentioned 3, but he said 4 during the summary.
there are only 3: Cranial nerves 7 (goes to the front 2/3 of the tongue), 9 (goes to the back 1/3 of the tongue), and 10 (goes to the back of your throat).
2:13-2:23
i cant do that
lets all take a moment to appreciate what Hank just did
I have no smell but ability to taste. Explain that
I just want to say, thank you for being so amazing! I'm in college, and you're videos are so helpful, and you are brilliant! Thank you so much!
I think I'll be looking forward to this season's outtakes a lot more then usual, if only to see the ones from this particular episode. Seriously, so much willpower involved...!
Do those molecules ever fall off the receptors? If so where do they go?
I guess they eventually get mixed up with saliva and we ingest it. That maybe why sometimes we feel tast of the food when we swallow saliva right after eating something
@@ivanchagasp That makes sense considering we also have taste buds in our throat.
I love how he just say "volatile compounds" so smoothly😂
Hello, CrashCourse. Just wondering: if each olfactory neuron has receptors for just one kind of smell, does that mean people who super smell like my mum have a lower threshold for action potentials to happen? or does it mean they have more olfactory neurons than most people?
I'm sure Olivia's tumblr blog was very moving.
I usually love the Crashcourse series. This one, however, gets TASTE versus FLAVOR mixed up. Smell happens due to the nose. Taste happens due to the tongue. Flavor requires both smell and taste. So for example, a person with anosmia has no smell, has normal taste (can detect all taste qualities), but cannot detect the flavor.
are we just gonna talk about pizza?
I'd like to know why anosmia isn't considered a disability if it is so important for sensing danger.
MK Mailler Because usually other senses kick in for dangerous situations. I have anosmia (from birth) and although I wouldn't smell smoke in my apartment, my smoke alarms would rattle my ears and I'd know the danger that way. Or perhaps I walked into the kitchen and saw with my eyes the haziness from smoke and then knew I was burning something in the oven. For spoiled milk I check the expiration dates all the time and I can taste slightly souring milk pretty well. There are very few situations where a danger can get me that could only be detected by smell so the disadvantage I have really isn't disabling or severely inhibiting me to function in the world.
Constant mild nuisance but not debilitating, I can see that.
I suppose I need to work on my workarounds and seek out more alternatives in how I do things. The spoiled food aspect has to be one of the largest problems I've faced.
You sound like a recent anosmiac. Thus I cannot offer advice on "workarounds" as I've never smelled before so I've never relied on that sense for things. I suggest checking out the /r/anosmia subreddit on Reddit for better advice on workarounds.
MK Mailler as an asnomic from age 10 due to a complcated mess of sinus problem.it's simply something you get use to. I had a few apptie issues when it first happend, but I just started eating weird things that I had no idea how they "should" taste, and just worked out from there.
I supose if I pushed hard enough, I could get a gas leak detector in my house but it's just not worth the effort
I honestly don't watch these videos to learn but because he makes boring topics interesting
A good way to demonstrate this is to close your eyes, grab a candy like a starburst or skittle and try and guess what flavor/color it is. You'll taste a sweet, fruity flavor but you won't be able to pinpoint what it is. You'll be sure its a red starburst and then be shocked to open your eyes and find that its yellow, the worst one.
These videos are all so helpful for someone struggling through their Psychology degree, I thank you
Forgive my ignorance, I didn't know that psychology classes also taught detailed anatomy.. Good to know..:)
Krishna I have a module called sensation and perception which is why :)
Ok cool.. Since you are a psychology student, may I ask you which mental disorder is most complicated to academically learn?... :)
Krishna I'm afraid I'm only starting my module on that this week so can't give you a very good answer! I studied depression at college which was quite straight forward, I imagine maybe a personality disorder or something uncommon would be more difficult x
All right Natasha..I wish you good luck in your studies...Enjoy your college.. :)
I don't know if anyone of you also has the same thing: I can smell an object without actually smelling it. I mean, when Hank was smelling the pizza, I also kinda... smelled the ham, cheese and so on. Not that it always happens, but I just have to focus and imagine how something smells and it's like my brain tells me that it smells the object even without it being there.
Is it that my brain remembers some smells and just recalls the sensual memories of how the objects smell? It's pretty weird and I hope I described it as well as I can.
Next time put the pizza on a plate😀😁
I could be wrong, but I'm pretty sure receptor cells express a single odorant receptor and converge onto single glomeruli in the olfactory bulb. So those colored receptors shouldn't all go to the same glomeruli.
I've red an article about umami. It was quite interesting.
Crash course philosophy
Ohh ohh yes! Also Crash Course Underwater Basket Weaving!
Salomon Flamenco When I saw that the new CC about intellectual property had the word "philosophy" in the title, I imagined you getting a wave of excitement before dying a bit inside. Please tell me that happened.
Max Spiegel I can confirm this did in fact happen
Salomon Flamenco My condolences, bro. I suffered along with ya.
Max Spiegel That also happened to me.
CrashCourse Both in the video summary and in the end of video review it says that gustation depends on four cranial nerves, but at 9:05 only 3 of them are enumerated (which is the correct number).
Did anyone else repeat 8:01 until they got it right? Just me?
"Lava hot, melty, cheesy hotpocket"
8:55 Hank, could I rewire someone's brain to make everything taste like poop?
I LOVE that there are different receptors for so many different smells! That's insane and beautiful.
awesome, I like being a people ;3
I've been anosmic since birth, and this video has taught me more than any doctor ever has. Thank you
Do you have any resources where I can learn more about the psychological and emotional effects of anosmia?
Jason Basgall yeah, go to school.
I agree. Its sort of silly that between animations he didn't take a single bit. I agree it's hard not to take a bite of pizza.
I like how parts of our body, like the Glomerulus, take their names from Latin words for something obvious. I can just imagine what that person is thinking when they're naming a part that hasn't been named yet.
"mmmm... this looks like a ball of yarn! but I can't name it Ballofyarn.. What's a word that sounds more cool and serious?? Let me fetch my Latin vocabulary book."
sounds like me in english class as I write my essays.
I love your episodes i swear this helps me alot with psychology ❤️❤️❤️❤️ i just wish u didnt talk so fast 😂 but u r a great teacher and very entertaining
anyone else here after contracting covid and losing theirs?
Well, I was TRYING to talk myself out of ordering pizza tonight. Thanks CrashCourse!
The claim of taste being 80% smell is unsubstantiated
Canadian bacon's good on pizza, but I can't stand pineapple in any way form.
Kharmitas what about shape?
Shape is a facet of form.
Kharmitas Amen, pineapple is gross in all its forms.
How w about as a fruit
Don't really like the taste.
In the end, I didn't learn anything. That pizza had 100 percent of my attention the entire time.
I can't smell eathir but I can taste... Questions
Gooooood lecture
My kids and I really love this channel and we are super grateful for all those making the videos, it's such a nice way to learn opposed to a textbook where we can't be sure we are pronouncing the words correctly.
My husband walked in right at "SMELL HER BREASTS FROM CLEAR ACROSS THE ROOM" and we both had a good laugh.
I have been waiting for this video for SO LONG!!!! I lost my sense of smell /taste when I was nine and no one understands just what that means in day to day life. Thank you for making this video!
i hate when i have Cold Because i can't taste and smell everything :(
I'm loving this course! Learning about my brain breaks my brain though.
Sorry Hank, Not eating a slice of Hawaiian pizza is not an amazing feat. YOU DON'T PUT PINEAPPLE ON A PIZZA. Just sayin.
after i finished watching this episode i went to go buy a pizza lol hawaiian pizza
I recently suffered the exact situation described in the video. I was cycling to work when I was struck by a taxi. After a few days in hospital suffering a bleed on the brain, fractured skull and heavy concussion, I suddenly found that I couldn't smell anything but what seems to be gas, and nothing has changed for almost five months now.
This has not only spoiled every meal and glass of beer consumed since, but also my work as a bartender/waiter. I have to impart my beer and food knowledge to customers when asked for advice and to pair food and drink. I can't recognise subtleties in hops any more, and find myself seeking out extremes in bitter, hoppy and sour beers simply to taste a lot of something.
Question: is there anything that can be done to 'retrain' by olfactory system into recognising smells again?
"The cell that replaces the cells that u burnt with a hot pocket "
How did he know?!?
Will you be doing any episodes on the urinary and digestive systems? :D
In this video, I learned that anosmia can be caused not only by head trauma, but also through respiratory infections and aging. I also learned that each olfactory neuron has receptors for only one specific type of molecule, or smell. These signals are then sent down the axons where several axons meet up at a glomerulus. At the glomerulus, mortal cells interpret the sensory information and transfer it to the brain. The information then travels to the frontal lobe and limbic system, hypothalamus and amygdala where it triggers a powerful emotional memory. Lastly, I learned that taste is almost 80% smell, and that when you can’t smell during a cold, it becomes hard to distinguish between different types of certain flavors (such as salty, sweet, etc.).
if my calculations were correct, this video starts at 0:00
"We are at the aarrgh" hahah so hungry😂😂
Good debunking, but the cranial nerves innervate tongue in a little bit different regions, and although all tastes can be detected over the entire surface of the tongue, different regions have different thresholds for various taste This differentiation was also shown by fMRI scan, showing different local activation on the insular cortex in the response to each of the tastes encoded by taste receptors.
still here senior year of college... help
