Dorsal interossei muscles of the hand

This tutorial covers the dorsal interossei muscles of the hand, explaining their anatomy, location, and function. These muscles, found in both the hand and foot, are bipennate and have two heads originating from adjacent metacarpal bones. The tutorial details the insertion points at the dorsal aponeurosis and proximal phalanx bases, highlighting their role in finger abduction and joint movements. Innervation is provided by the deep branch of the ulnar nerve. The video concludes with a call to explore more anatomy resources on Ken Hub.
