At the start of this school year, I started taking anatomy and physiology. I immediately fell behind, and within two month I went from a A to an F. I found this channel TWO weeks ago, and after watching every single video on the anatomy and physiology playlist, I went to my teacher asking to reassess everything I had done so far, (my school has a endless amount of retake policy so I was able to reassess them all). After redoing every single test, (which took two weeks), I was able to return everything in. I just got my grade updated today, as the last thing has now been regraded, and I now have an A. And I am now one of the best students in class because of you. Can't thank you enough, and please keep it up!

[charlene]

Thank you so much, you saved my day. I'll recommend this channel to my classmates. More content please for anatomy and physiology. It really helps me as a nursing student.

[Roro]

Sir you have changed my lifeee. Appreciate that so much sir. May you and your family receive all the love and success . Can you post about all the blood supplies of the body nerve supply arteries, veins? Its quiet challenging to remember

[hamdhanawaz]

The word 'Thank You' is not enough to thank you but I still say Thank you since there is no any other way to thank you.Most of my long-term doubts have been cleared

[مهدیاحمدی-قصح]

hello I wish you would make a program about the polio virus and give a full explanation. My brother's right leg is involved and he has very weak movements, or would you make an animation about this and explain where the bundles of motor nerves are cut off.

[PavanKumar-bcxk]

Sir please make a video on Atrial and Ventricular pressure changes during cardiac cycle

[AitanaBanuelosRoch]

Hello, can you explain pleas why the horns are Dorsal Lateral and Ventral instead of Posterior Lateral and Anterior? Thank you for your video.

[badisa]

at 8.33 min, inter-neuron in grey matter -unmyelinated - crosses over to other side of the spinal cord, enters into the white matter and goes to the brain. Question: when in white matter and during its travel to the brain, is it myelinated or will it still remain unmyelinated?? some one please clear me of this doubt. thank you

[jennyezekweh]

You are just amazing, thank you so much for making these videos

[preddyg]

Your explanation is so precise and clear❤

[fadedillusions]

You have such wonderful videos. I have both RMS and severe cervical stenosis (central and foraminal... going for a 4 level acdf next month); so, much of my spare time is spent studying.

[umamahrehman]

Thank you SO much. Trying to revise (i.e. learn for the first time properly) neuroanatomy and this was so so helpful!!

[Adjudicator-noneofyourbuisnes]

Sir,
Can you make video on scapula and the major bones...your description is the best I have ever seen
I am studying in Medical College in India

[adesinafadekemi]

this is the best explanation of the nervous system I've seen. thank you so much.

[Medboy_]

Please sir, can you make a video on brachial plexus 🙏🙏🙏
