[@maxmustermann7079]

Dunno if you'll see this, but I wanted to thank you for your great videos! I'm a med student in Germany and just passed the somewhat equivalent to the USMLE1 that we have to sit here. Used to watch your videos in the evening the last weeks when I couldn't concentrate on textbooks anymore, and they were immensely helpful!!! Keep up the good work, much appreciated, and I look forward to more clinical videos (which'll become relevant to me from now on :) ).

[@saskia617]

As a first semester med student in Germany, I can wholeheartedly agree to this! These videos are saving my life right now. It's the first time that I actually understand embryology. Thank you so much!!!

Thats incredibly intelligent., I wish I did that in the beginning. But you live and you learn. Studying for STEP 1 here.

As Medical students of the whole world, we should give in the little we have and we support this KZbin Channel, there is no difference between watching Zach's videos and reading Text books, actually Zach's videos are more better, each time I watch his videos, I make notes, and when I go for Lecturers am the happiest Dr. Cz everything the lecturer talks about I know it, may God bless you Professor Zach, you're a blessing to us 🥰

“We have created man out of an extraction of clay (the origin of semen). Then We placed him as a sperm-drop in a firm lodging. Then of that sperm-drop We created a leech-like clot, then we made the clot into a lump (of flesh). Then We made that lump into bones, and We clothed those bones with flesh. Then We developed him into another creation. So blessed is Allah, the best of creators.” (Quran translation of 23:12-14).

This is AWESOME.... but 3-5mg of folate? The guidelines all say 400mcg folic acid (or 650mcg dietary folate equivalent). Is there something they're not telling us?

[@suzannakyazze5837]

Day 15-17 The notocord releases growth factors and makes the ectodermal cells to proliferate. The ectoderm thickens and forms the neural plate. The neural plate forms into neural folds and neural groove Neural crests cells form around the edges of the neural folds Neural tube is formed The neural tube has a cranial and caudal end The cranial part is anterior neural pore and caudal part is posterior neural pore The neural pore are still open before day 21 but close after that Folate makes the neural pores to close If it doesn't close you get Spinal bifida Around day 24 ant.neural pore closes and around day 26 post.neural pore closes. Vesiculation Cranial end of neural tube It has 3 vesicles 1.prosencephalon, mesencephalon, Rhombencephalon Primary vesicles are formed Prosencephalon>>telencephalon+diencephalon>>cerebrum Mesencephalon>>mesencephalon>>thalamus,dorsal thalamus Rhombencephalon>>metencephalon>>pons, cerebellum,medulla,spinal cord Neural crest differentiation. Become Melanocytes, chromaffin, enteric nervous system (submucosal plexus), dorsal root ganglion, layers of the brain,pia matter, arachnoid matter(leptomeninges). Caudal end of neural tube. Outer layer is marginal zone, middle layer is mattle zone then neural epithelial zone Alar plate is formed dorsally, ventrally the dorsal plate Inside of the plate is cerebral spinal fluid

I have to say, Just came across this video because I study this in Hebrew(from Israel), and I didn't understand shit and our teacher is fairly good at explaining but the way they switch from latin to hebrew make it super hard to understand where you at. so I searched an explanation of the development of the nervous system and came across this ( I am studying psychology so it's super hard for me to understand since I don't have a background in medicine), and my point is -- Ninja nerd, the way you teach is unbelievably good, I enjoy every second of this video and learnt so much from it while saying excited, This is some next level teaching, Thank you!

Thank you so much for explaining this topic so well! I've always had a hard time trying to picture the formation of the CNS and PNS (let alone the entire body structure) from the neurulation stage. I really wish all professors/instructors teach like you. Again, thank you so very much!

That's what happened cuz we really that's why you're looking at for BBM cuz we're here is when you had said one is wrong when I got free and and development when they're all teaching circulation smile everybody CEF alon all right ically there's another part of peanuts that are coming off and then it would have been when auntie had went in of the other people that were quick TV and had moved something to him somebody said sir did that did she hurt you did she jerked your hand because what happened was when you're doing in between it's just a different page that's why that's okay for you to continue to move to show to move to get it between them and not with you between medical and trauma or as you in the Harrison Hall
