Learn More Frequent questions What is the abductor digiti minimi muscle? The abductor digiti minimi is a hypothenar muscle located in the hand, specifically the most superficial among the hypothenar muscles. It plays a crucial role in the abduction of the little finger. What are the attachments of the abductor digiti minimi muscle? This muscle originates from the pisiform bone and the tendon of the flexor carpi ulnaris, inserting at the base of the proximal phalanx of the little finger. These attachments facilitate its function in finger movement. What is the primary action of the abductor digiti minimi? The primary action of the abductor digiti minimi muscle is to abduct the little finger away from the other fingers. This movement is essential for hand dexterity and grip. Which nerve innervates the abductor digiti minimi muscle? The abductor digiti minimi is innervated by the ulnar nerve. This nerve supply is vital for the muscle's function and coordination of the little finger. How is the blood supply to the abductor digiti minimi muscle provided? The blood supply to the abductor digiti minimi muscle comes from the deep palmar arch. This vascularisation supports the muscle's metabolic needs during its activities. Rate This Article
