**Correction*** Hey Ninja Nerds!! The laryngeal cartilages are actually derived from the 4th and 6th pharyngeal arches NOT the 1st!!! Sorry about that ninja Nerds!!! Hope this video is helpful! Love you ninja Nerds!!!
Hey, sorry I think the part where you explained the process of differentiation of fingers got deleted or skipped? Thank you!
I was going to correct this. Good job
Tnx
hyoid bone actually derives from second as you said in pharyngeal apparatus video

I love it when Zach says things like, "isn't that cool?!" I swear having an excited, passionate teacher makes SUCH a difference. Thanks, Zach!
2:55 he even says "neural crest cells" as if he just met the love of his life for the first time AHHAHA great lecturer!!
Hey man can you tell me something I'm a bit confused about it
Is it Thyroid hormone or estrogen which triggers endochondral ossification of epiphyseal cartilage in the long bones during puberty?
A Pakistani med student here, trying to study embryology from scratch 2 days prior to the exam. Thank you for your energy and explanation!
Same here , used to overestimate it, but it’s such an exciting subject, kudos to Zach sir
Development of limbs
1.HOX, TBX4 & TBX5 genes determine the position of formation of limb buds. Once activated, they stimulate release of FGF-10 (fibroblast growth factor).
Ectoderm grows off as 4 limb buds. Somatic layer of lateral plate mesoderm moves into limb buds. FBG-10 stimulates a thickening at the tip of the limb buds called apical ectodermal ridge (AER).
AER secretes FGF-4 & FGF-8 which causes proliferation of somatic mesoderm. the most distal part keeps proliferating (progress zone) while the proximal part of limb bud starts to differentiate. From cartilage to bone (endochonrdal).
Some tissue in AER undergoes apoptosis due to bone morphogenic protein (BMP) & retinoic acid increase. Starts to form fingers. Mesoderm starts to proliferate to make finger bones. AER dies off to stop growth.
Tissue called zone of polarizing activity (ZPA) develops on posterior disal limb which causes the asymmetrical growth of the hand. Thumb to pinky.
sincerely, thank you for this. you have made my exam period at least an hour or two shorter.
when my med school prof lectures about this subject she just throws it all up on one powerpoint slides and talks through the whole thing at once, which i find very hard to follow and understand. drawing it out step by step like this is immensely helpful, thanks!
Zach you are my mentor and hero. You don't even take Sundays Off! Thank you so much. God Bless you and everyone
We are always in your corner! No days off! 🤓

Nerdology : Development of Ninja Nerds
😂😂
That would be the study of ninja nerds. The development would be called Nerdogenesis. 😉
i'm an Italian med student and I actually prefer this to may Professors. Thank you for everything you make Zack and crew
I am an Iraqi med student. Definitely, it’s better than what the professors give. It’s well organized and simply explained and understandable
Am a proud Ninjanerdian 🎉. Thanks buddy 👍
I just wanted to say a most sincere THANK YOU! I really appreciate your work and you must know how much it helps everyone who wants to learn. Thank you again ♡
Hello Zack, I’m a medical student from Iraq, and I just want to thank you for all the work and time you’ve given for everyone who watches your videos.
You explain in a such way that is comprehensive yet still fun and enjoyable.
Keep going man, wish you the best of luck!

Embryology😻 The greatest gift ever for my upcoming semester. Thank You Mr👍🏻👍🏻👍🏻👍🏻
In love with his way of teaching 😭❤
Zach is a treasure that must be preserved!
Brilliant as usual. But what i really want to thank you for is your positive energy. I woke up not in the mood for learning anything about embryology 😂. But the way you explain and the way you seemed so excited is so refreshing! And contagious.

I just got my psychotic preworkout in the mail! Omg!!! I feel the electrons coming out of my membranous neurocranium!!! Thank you Zach!!!! Biochemistry major let’s do this then MCAT!!
Its 3:00 am, i have an end of sem 1 exam and things just escalated quickly from neuroanatomy to embryology to bchem...am glad this made my work 1000 times easier
Thank you, thank you, thank you!
Keep it up with embriology!

One interesting (important) fact: The nucleus pulposus is the only remnant of the notochord, not sclerotome!
Sclerotome gives rise to vertebral bodies, annulus fibrosus of the intervertebral discs and ribs!
Lots of love from Medical School of the University of The Gambia🇬🇲🇬🇲🇬🇲🇬🇲🇬🇲🇬🇲Thank you so much for your videos.. you're just Amazing!
I swear I have NEVER even considered signing up for Patreon for any other channel except this one. I hope I will in the future.

Holy smokes! 1000 Likes and 0 dislike! Zach you are amazing!
Wow ...thank you ...your all videos are interesting...you make me love 😘 the medicine...
I really love this embryology series in so many ways. I have one question, though. I'm not an expert, but my previous studies of limb development have suggested the importance of the DIGITAL ARCH in the stepwise development of the wrist and digit bones STARTING WITH THE PINKY...and then arcing around to eventually form the thumb. This video makes it seem like the digits form all at once. Am I mistaken about something? Or am I presenting a contrasting view of a debate within embryology? The digital arch is also what differentiates the autopod of a tetrapod from the lobe-finned ancestor..... OR SO I'VE BEEN TOLD. Thanks so much for this content!!
Now this guy is just exceptional
The lecture is so nice, understandable and interesting,,add more for us!!!!
Thanks for your efforts Ninja crew
thank you so much for such an effort and explanation
Thank you so much for the embryology lecture!!! Just want to make sure that does hyoid bone and laryngeal cartilage comes from 2nd~6th pharyngeal arch. thanks a lot
Watching your videos from somalia 🇸🇴 and thank you for sharing these wonderful videos with us (med students)

He is the best believe me.Anyone who is reading comments to see whether he is good just follow his lectures.Explaining embryology is really difficult but still he is from another planet.
Always wait for your videos
Thank you ninja nerd. Please where does the clavicle, scapular and hip bone develop from?
U are really fantastic thank you for everything
