Zach, i dont know if you will read this, i hope you will. I watched this video on my 1st year of medschool for histology class. I loved it, i finally understood all of those details and remembered them with ease. I was best in my class because of you. And more importantly, i really fell in love with medicine and human physyology. Years passed, i learned alot of disciplinnes, i encountered many many difficulties, i grew up as a clinician, i struggled under loads of information. But i sucsessfully made it to my 5th year. And now im on my gynecology rotation where i need to remember all of this again. And of course, i came here, back to this video... And i have to tell you, that thrill and exitement you gave me years ago is still there! You do not know me, but to me you are an old friend who explained me so much... You really helped me, you know... Thanks, brother! I didnt think that i would tear up, but im finishing this comment with watering eyes... I hope you have a fantastic time and amaizing friends around, not many people are so priveleged to influence so many people as you do. All the best to you and your team. Thanks again!
My Same Story ❤️
This comment is making me cry 😢
Seriously! he is blessed. Lots of thanks to him from my side too..thank you prof.zach for being so Fantastic teacher.
Revisiting in my clincial years too.
I feel you, because thats exactly how I feel when he explains things thoroughly yet so easily.
As soon as I start earning money, I will be donating to this channel. You, my friend, are an AMAZING teacher. You have taught me more in 30 minutes than my professors have in 10 weeks. Thank you for existing! I owe my passing grades to you.
I'm a med student and i don't earn money as well but I signed his patreon anyway and I give him 1$/month. Obsly it aint much but if everyone who watches his videos did that it would help for sure, and it's my way to thank him for this amazing work :)

He's just a miracle I'm a med student I love him so much ❤️❤️❤️❤️
I am myself Endocrinologist and thoroughly enjoyed all your Endocrine basic lectures. Highly recommended for Medical students, Drs, and even specialists. You are really doing a great job by teaching such complex stuff in an easy and friendly way. I wish I had such a teacher in my MBBS days. Hats off and best of luck

Endocrinologists don’t watch stuff like this 😂 If you really are an endocrinologist and you’re actually interested in detailed understanding of how the human body functions 🧐I am pleasantly surprised. I thought “Endocrinology” translates to “The END of ology” the end of the study of something 🤓I know it really means “within” “internal” or “inside” study 👀🫣but most endocrinologists seem to imagine that THAT means they just learn everything from within themselves. That’s just what I think bcuz they don’t ask questions, have the least curiosity about what the patient is experiencing that I’ve ever witnessed and they get annoyed with external sources of information (ie: their stupid patients telling them ANYTHING)
😂😂🤣😅
i really love this guy so much he just delivers the information in the best way possible, the video is 30 minutes long and it felt like couple of minutes. keep up the good work.
Same! A long video gone by so fast that i was kinda sad when it was over
These days when websites are charging students for even MCQs. It is very tough to praise your team in words with my not that much enriched vocabulary..I am not making that much money..I will start earning from next year once my residency starts(Hopefully) and I will contribute first that to your channel..God bless you and your team..
So happy you can benefit from this channel! 👍 Thanks for your support!
A year has past :)

Amazing! I've been a Nurse for 14 years and have now decided to return to school to get my BSN at the age of 40! This video is extremely helpful, just wish I would have found you 2 months ago! :)
Hello
Hello from Nigeria… it’s my first year in med school and it’s 2 weeks to write our exams and by just watching this video 3 times I can understand the whole process… thank you Ninja❤
Omor I’m also writing embryology exam soon 😪
THE fact this man learned this and is teaching us more than our teachers or parents have makes me cry. This dude is fantastic
I’ve never seen a better educational video in my life. You’re the man!
I’m serious but all of your videos have allowed me to get an A on every exam of A&P II. Thank you!
Great job! - TG
I’m doctor from Brazil and I want to congratulate you, Zach Murphy, for your amazing job! Your passion for teaching is crossing the oceans! Christ bless you!
You have no idea the impact you have on everyone watching you! Your passion is contagious! Seriously, my heart feels happy when I watch your lectures. Thank you!
I bet professors around the world are watching this to learn what they don't so they can teach more accurately. But the students who really want to do well as what teachers don't quite get, will just watch this a bust through with an A. You're under-rated. I hope TH-cam is paying you lots for this successful postings! You guys are awesome. Making it happen better than most and loving it too! I really like the episode on the immune system where you went into detail on the 3C process.....stellar. I consult a handful of anatomy videos for my learning....this is on the top. Thanks for making anatomy, physiology FUN and EASY!
don't understand why professors cant do this your videos have been so helpful!!
S absolutely 💯
Your lectures have never disappointed me! You have been my best online tutor so far. Without your insightful lectures, I would not to get thru my anatomy class with a good grade. I am truly appreciate your time and dedication in sharing your knowledge with others.
It takes a true genius to simplify the complexity of these topics. Thank you, you LITRALI saved my (stud.med.) life - Chris Traeger
Absolute legend! I've never heard anyone explain this so thoroughly. First the first time I can actually say I understand this well enough to be able to explain it back to someone and fully comprehend it. Thank you so much!
Studying for MCAT and I made such a good decision of watching his videos to understand biology concept, its just makes you feel so confident and actually understand what is going on!!! I wish he made more MCAT focused videos as well!
Ap ka slection howa ? I mean ka ap na MCAT clear kia?
My goodness you are amazing at teaching! Honestly, you were engaging, made it easy to understand and keep up. I would take your class in a heartbeat. Thank you for these videos!!
you're the best. who needs professors when you explain it so thoroughly! I'll be sure to donate when i'm not a student anymore :)
I'm a medical student. certainly, this channel is better than my university. My classmates ask me always: where did you get this huge information? definitely, I say to them " Ninja Nerd channel is the best university than universities in whole world!" I would like to appreciate you for your great work. you deserve my university's fee.
The way you explain, no one can beat that. Amazing!! Things were not this clear to me before I saw the video.
In case you are wondering, HOW the Estrogen feedback on the pituritary changes from negative to positive in the late follicular stage. It's because the accumulating Estrogen actually increases the GNRH sensivity of the gonadotrophs. Therefore the gonadotrophs release LH excessively and cause the LH surge.
Ive had this question in my mind for so long..thank you😄
Since GnRH neurons do not have oestrogen receptors (ERa), oestrogen bind on to receptors that are on the Kisspeptin neurons in the hypothalamus, in which they activate GnRH neurons through GPR54.
This indirect mechanism allows us to understand why high levels of oestrogen coming from the dominant follicle can increase the activity of GnRH which in turn increase the secretion of LH --> Ovulation.
However, in the 7th day of the follicle phase, the oestrogen inhibit the secretion of FSH so that only one follicle will grow to be the dominant one under the stimulation of low levels of FSH (due to the inhibition).
We can say that high oestrogen levels have an indirect positive feedback on the GnRH neurons through KIsspeptin, which in turn increased LH secretion, but the negative feedback mechanism for inhibiting FSH during mid follicular phase i couldn't understand. Maybe someone would.
@@noble-quran_hadith the same growing follicle that secretes Oestrogen secretes Inhibin hormone which inturn inhibit secrerton of FSH.
May I ask, how the estrogen goes up again in late follicular stage after its production drops due to inhibition of LH and FSH by earlier high level of estrogen?
Estrogen levels continue to rise as the follicle develops. Progesterone eventually begin to rise as well. Up to a certain point, the estrogen being produced exerts negative feedback on both GnRH and gonadotropin secretion.
Around the 14th day of the cycle, the anterior pituitary abruptly changes its response to the persistently high estrogen levels. Rather than suppressing gonadotropin release, the estrogen now has a positive feedback effect. The reasons for this switch are still not clear.
The switch to positive feedback provokes a steep surge in LH, and to a lesser degree FSH. High LH levels in turn initiates the process of ovulation, whereby the follicle ruptures and egg is released.
After ovulation, the follicle collapses and the cells within it transform. This new structure is called the corpus luteum. The luteal cells produce more progesterone than estrogen, so blood levels of progesterone rise higher than estrogen levels after ovulation. The corpus luteum only remains viable for about 14 days, after which both estrogen and progesterone levels taper off. The declining levels of estrogen remove the negative feedback on GnRH and FSH production, allowing the cycle to begin over again.
I really love your work and the way you explain the stuff !!! I can re-read the same chapter 30 times and will still not get it, watching you explain it with so much enthusiasm makes my day and keeps me wide awake to learn more, I actually had tears in my eyes when I finally understood it and it all just made sense !! Thank you so so so much. You are simply great and I just cant thank you enough. And for the record, this is my very first comment on TH-cam, because you guys deserve it. God bless you !
This is so easy to understand compared to the books from school. Thank you so much for your detailed explinations. It really helped a lot. Great job and keep doing these amazing lessons!
My favorite part was the fimbriae making gnarly waves scooting the little oocyte... super helpful video, really makes clear the roles of the hormones at different phases, thanks!
Such an intelligent human being, your facial expressions and the quirky way you say things sometimes, hilarious. Love it. 👍
i never understood this when my class teacher explained it to me.. but your explanation was awesome.. i understood eachand everything... my dream is to become a gynecologist..hope this really helps me in future.. may god bless you brother.. to increase your knowledge more
I'm a midwifery student and this video was what made the hormonal cycle click. This is so great, I shared with my fellow midwifery students to learn this. You did an amazing job of explaining everything and tie it all together. Thank you!
This is quality, the visual aspect combined with the clear descriptions is the perfect combination, lots of information that is being put into a simplistic yet effective story. well done and thank you.
He explained this sooooo nicely.. I would never forget the process and a massive thankyou.. a big part of my test concept got cleared.. So understandable! Thankyou once again and I am highly grateful!! ❤
most of the videos that I have seen on this channel are long, but he explains everything in such a way that my brain can understand!
yesssss, you're awesome man, watching yours videos from Brazil, recommending it to all my friends, thank you very much for your job, a big hug!
You don't even know how much you are helping me, I feel so angry because I can't never focus on what my teacher are saying but with you it's so different, I can watch you all day and understand and focus on what you are saying, THANK YOU SO MUCH.
I don't have much but I will support you on Patreon! Thank you again
I love how you speak and how passionate you are about science. It reminds me of myself.
you explain the whole thing much better than my lecturer! Thank you, this really help me a lot.
I’ve watched a lot of these and liked them and you guys are by far the best! Where has this been all my life?!
You are an amazing teacher. I NEVER had seen such a detailed and accurate explanation. THANK YOU SO MUCH.
5 mins into this and I realized that this is exactly what I needed all this time.. thank you so much, sir..
I was so confused when I was reading Embryology from the textbooks but after watching your videos and observing the huge effort and dedication you've been putting into making them and making such complex concepts of medicine really much understandable I have nothing to say except they I wish you the best in your life and carrier. God bless you. Thank's a ton.
I absolutely love your videos man. the way you present complex systems information is the most coherent ive ever seen. I also love that you are willing to give them out for free so that poor medical students such as myself can use them. Thank you for being you. Love from australia
Hhhh at first i was just like “ it’s too long,who will be looking at such a long video ”,, but now I’ll confidently say it was the best really👍🏻👍🏻👍🏻many many thanks for your amazing explanation ☺️
My first thoughts as well... However I'm so glad I watched it through! Extremely helpful and informational!!!
Omg same here and i was actually kinda sad when the video ended
Same, i used to skip his videos and now he is like the only one i watch! So worth it
I strive to one day be able to express myself as amazingly as you do when teaching all about anatomy & physiology. Thank you so much for delivering information so easily and clearly. Whenever I'm stuck on material I always come to my Ninja Nerd instructor online and easily understand everything
😭❤️❤️❤️I really appreciate what u r doing, not to insult most of science classes’ instructors but they have to take their seats in the classrooms listening to ur lectures with their students and learn what real lectures look like 😂especially those who come to the class and read the slides to their students then leave 🤬
Exactly,and that what happend in our collage the doctor leave and u don't understand the purpose from lecture he only say are you understand we say yeah but actually no one get the idea😕
Ninja really forfit alot of respect.
teba younis I believe so😍
😣👍
WHY ARE YOU SO UNDERRATED!!! You are amazing
Not anymore
Well he is a ninja
Why don't we have him in our medical schools 😢
@@bhavya6026 can't afford him he is priceless
When you kept saying how cool these phases are and how cool how cool women’s processes are brought me joy. My professor has used hurtful/shaming language calling a women’s hormonal cycle “confusing” or “complex” at the end of each slide he presented. I’m understanding more from your videos and am more appreciative in the ways in which you hype up all that you’re teaching and not dreading it. Thank you.
Love the fact that you get so mesmerized by your own creation and feel the awe when you know it is being explained so so properly.
You are the best, really, saving my life at med school
Super detailed, clear and made easy, thank you for making such powerful explanatory videos!
Thank you so much for the amazing lecture. I am on the TTC journey. Learning how my body works, I am becoming more grateful and patient with my miraculous body. Thank you!!
You’re awesome man, I really appreciate you taking the time to make these videos. Wanted to know if you could make videos on gastrulation and embryogenesis?
This is better than binging Netflix to be honest.... love these videos!!
thank you so much for your videos, im keeping up with your videos as a substitute of some lectures i dont quite understand, thank you for your great work man! youre helping us so much
Thank you for your effort!! Loving these videos, they are helping me so much preparing my exams in medicine
Awesome stuff,guys!What confused me till now has become crystal clear.Can’t thanks enough.👌🏻🙏🏼
You are teaching us generation x things we didn't learn that we should have. Thank you so much for the work you've put in to get here to guide us.
I donated 5$ it's a little contribution for the amazing work you do for us !!! Thank you !!! you explain very clearly
Thank you sooo much, your videos are the very best I've come across so far..... I do hope you continue to grow and reach out to many cause there's not a lot of lectures who teach like you do.
It s been a while since I stumbled across an old ninja nerd video. Zach had such a cute baby face and baby voice😭
That's the best physiology class I've seen. You rock man
Thank you! This video is so great, it makes complex concepts super easy to understand.
Awesome...no words to praise your hard work...No, not a single teacher in my area can explain this cycle so beautifully as you have explained... love from India❤️❤️
Wow! I am a first year MBBS student and was not able to understand embryology but you are the legend who helped me to understand each and every word . I take your lectures of every subject and study from your lectures . Thank You so much sir . Your new subscriber ❤️
amazing video! i have a really short attention span so the way you speak and your color-coded drawings really help me understand the topic.
Your explanations make every topic both understandable and interesting! Thank you!!!
Wow! Your are an amazing teacher! I came in wanting to learn the basics but you taught me much more and the reasons as to why it’s occurring. I’m mind blown. It’s the first time I’ve watched a video of yours.
Thank you.
Hi- this was the first video I watched of yours in my undergrad endocrinology class. I feel in love with hormones and repro. Now I am in my first year of medical school watching it again for review- thank you for making these and helping us science nerds understand and appreciate the complexity of the human body
In 2024 !!after 4yrs Dr Zach video is still saving lives !!! Thank you so much ❤
Just speechless🥺🥺
All I can say, may God bless the good works of your hands🥺❤❤
You're really helping many people globally to enjoy the most complicated courses in a matter of minutes, with clear and understandable contents.
Much love❤❤❤
maaaaaaaaan this is crazy, sooo much information, with a so in love teacher with the subject, amazing video mannn FOR REAL
I am a lecturer and am grateful to have encountered you. You are an inspiration and my mentor in giving engaging lectures. Keep up the great work. Thanks a lot Zach.
thank you for sticking through the whole process of making this video
The best video on this topic that I've seen so far. Thank you!
Zach, thank you for doing what you do, man! This is beyond helpful material (not just this video, your entire catalog!)
Your have a way of explaining these complex pathways so easily. Thanks for the video!
I tried so hard to fully understand the system until this video. You helped a lot, thanks!
Hey man, just wanted to say you're amazing. Thank you and keep going your content rocks !
you just topped my professor with your explanations. im understanding this MUCH better thank you
An explicit and eloquent lecture it was. Thank you sooo much for your dedication 🙏 👏
I simply LOVE YOU!!!!!! Straight forward, informative, and engaging! seriously you have a GIFT for TEACHING. THANK YOU!!!!
You are sooo good the only one i understand keep going even thought i study in french there isn't many vids in french and your explanation helps me understand my lessons in mèdecine better
Firstly thought that the video is very time consuming but this person so good in this that every body will understand this very very well.. Thank u very much sir..Great lecture..😮😮
Hey! just wanted to add something to your amazing explanation. The second stage of the ovulation cycle (Luteal phase) is actually ALWAYS 14 days.. it's the follicular phase that changes from every person to person or cycle to cycle, so it makes the cycle longer or shorter.
keep up the great work! love your videos!
14 days is average, but it's not fixed. Luteal phase length can range from about 11-16 days.
ur amazing ninja.................i pray u get more in life,what ever u wish u get more success....
ur amazing
You're the best teacher I have ever seen
Great video and content! Love his drawings and visual teaching - soooo good indeed!!! Thank you 🙏
I have just found the PERFECT channel.
you are one of the BEST in explaining the processes that happen in our body.
thank you very much👏👏👏
Amazedddd by your lecture sir... Perfectly understood the endocrinology of female reproductive cycle
Thank you Ninja, it was super helpful for me.
I'm here to learn about our bodies and their complex mechanism. You are such a wonderful teacher. All those scientific terms were easily understood because your mode of teaching is super good. Thank you.
Thank you so much for explaining this topic in such a beautiful way! 👏👏 You made everything so easy & crystal clear to understand. 🙌🙌
Thank you so much. 3 weeks i have been reading and reading but still couldnt get it. This video really made me understand it all. Thank you so much.
I was watching this video and watching you for the first time last year for my biology class of the last year in high school..
Now, I'm watching this again..but for my lecture in first year of medicine
so, thanks a lot
I just love the words and the method of explaining.... It made easiest and also applies to every good book content....
as turkish higschool student with a not so good bio curriculum this is really helpful our theachers are really bad and lean towards memorising rather then actually learning the physiology thank you for doing this it helps a lot
this helps me a lot in medschool. your videos are amazing and a lot better than my prof's recording videos:(
Thank you and love you is all I can say to you guys
You’re literally my medschool heros ❤❤
This channel has saved me tears and so much sleep. Thank you, thank you, thank you. You have a GIFT for teaching
You explain me better than anyone about this process. Thank you.
I am wondering how you clearly and undoubtfully explained all the things... you are great yourself.... no words more.. 👏👏👏
you have really helped me so much even things that seemed to be too difficult for me but after watching your video its a thing of the past
