Hey Meditay!! 👋🏽👋🏽 Please consider doing cranial nerves? 🤗 You’re the only one that I know that could explain it better. I’ve watched all your CNS videos.

One of the greatest resources for every med student...meditay is simply the best
This is a helpful video! Thank you so much! May I suggest that next time please include the innervation of the muscles
This was a really amazing video. Thank you so much
Gratz, respect from Kazakhstan national medical university 🙌🏼
Flexor Carpi Radialis does not adduct the hand, it abducts it (radial deviation).
Soooooo beautiful ,God bless u our doc ❤❤😍
Amazing video sir
You cover every hard muscles of forearm just in one video in easiest way with easiest animation
Tysm sir !
God bless you❤️
