Hypothenarmuskulatur

The tutorial by Ken Hub covers the hypothenar muscles of the hand, focusing on their origin, function, and innervation. It details the four muscles: abductor digiti minimi, flexor digiti minimi, opponens digiti minimi, and palmaris brevis. Each muscle's function, origin, and attachment points are explained, along with their innervation by the ulnar nerve. The tutorial provides a comprehensive understanding of these muscles' roles in hand movement.
