Musculi interossei palmares

The video tutorial explains the Musculi Interossei Palmaris, a group of three muscles located in the palms of the hand. These muscles originate from the lateral surfaces of the metacarpal bones and insert at the dorsal aponeurosis. They are responsible for the adduction of the little, ring, and index fingers towards the middle finger. The tutorial also highlights that there is no interossei palmaris muscle on the middle finger, where the ramus per fundus of the ulnar nerve takes over. The muscles also aid in flexion and extension of specific joints.
