You put the 2nd pharyngeal arches skeletal structures --> stapes in the muscles box! Fab video, I really enjoy the background details you are providing it really helps me visualise this development rather than just memorise blindly what all the derivatives are. I also appreciate how you are including both the pouch and the cleft as you go along which again is very logical. Thank you!
Your channel is the most concise yet informative for simple, detailed information! I love the way you both explain with clarity, thank you so much for your work!
thank you for such a helpful lecture but i wanna point out a mistake.. you said that thymus originates from dorsal component of third pharyngeal pouch and inferior parathyroid gland from ventral component but in actual it is opposite i-e thymus from ventral and parathyroid from dorsal component. Thank you!
Hi Dr. Matt & Dr. Mike: Thank you very much for the excellent lesson. A question: I was wondering if the pinna (external ear) is also a branchial derivative. I noticed that individuals with First & Second Arch Syndrome (very rare) often have an underdeveloped or an almost completely absent external ear. Thank you very much.
Hi John, sorry for not getting back to you sooner. Yes you are correct, the external ear is derived from mesenchymal tissue from the 1st and 2nd arches. Also, because it develops from atleast 6 different buds of tissue, there is great variety in the outcome of the pinna's shape etc.. And, obviously it developing malformations, usually this associated with kidney and/or pharyngeal arch deficits.
Among all videos I have seen you make these embryological are the best. You have good structure and paint stuff clearly. This series helps a lot!

this is the only videos that explained it wel ! thank you !!!!
Helped me alot thanku very much do more videos on embryology
Very impressive. Thank you for uploading these videos.
best doctor ever!!!!..thx very much
Excellent video!!
Very good.....learn a lot from it keep it up
Can't thank you enough for this video!
Thank u sir keep doing it
million thanks, u r doing g8 job

Hi Maryam, yes you are indeed correct. Thanks for pointing this out.
Cardiac embryology videos please

Great video! But I thought there were 5 pouches and only 4 clefts.
Hi Luke. What resource did you obtain this information from?
Thanks . Nice video
superb thanks a lot
thanks alot
very helpful
thanks
Thank you very much
Thyroid develops from ventral wing of 3rd pouch and inf parathyroid glands develop from dorsal wing. Please correct it.
The thyroid develops from the foramen cecum of the tongue, via the thyroglossal duct.
not thyroid ...
thymus from ventral wing of 3rd pouch
inf parathyroid gland from dorsal wing of 3rd pouch.
what about the aortic arch
do video of thyroid treatment to clinical assess
