The term "hypothenar" refers to a group of muscles located on the palm of the hand, specifically on the ulnar side, which is the side opposite the thumb. These muscles are responsible for the movement of the little finger and play a crucial role in hand function, allowing for actions such as gripping and pinching. The hypothenar muscles include the abductor digiti minimi, flexor digiti minimi brevis, and opponens digiti minimi. Together, they help in the coordination and dexterity of the hand, contributing to various tasks that require fine motor skills.
