Abductor Digiti Minimi (Foot) - Podcast Version 0:00 / 0:00 1x 0.25x 0.5x 0.75x 1x 1.25x 1.5x 1.75x 2x The abductor digiti minimi is an intrinsic muscle of the foot. It is located within the first (most superficial) plantar muscle layer of the foot. Attachments: Originates from the medial and lateral tubercles of the calcaneus and the plantar aponeurosis. It attaches to the lateral base of the proximal phalanx of the 5th digit. Actions: Abduction and flexion of the little toe. Innervation: Lateral plantar nerve (branch of the tibial nerve). Blood Supply: Lateral plantar artery. By TeachMeSeries Ltd (2026) Fig 1The first layer of plantar muscles. The plantar aponeurosis has been cut to reveal the underlying flexor digitorum.

Learn More Frequent questions What is the abductor digiti minimi muscle? The abductor digiti minimi is an intrinsic muscle located in the foot's first plantar muscle layer. It is primarily responsible for the abduction and flexion of the little toe. Where does the abductor digiti minimi originate and insert? This muscle originates from the medial and lateral tubercles of the calcaneus and the plantar aponeurosis, attaching to the lateral base of the proximal phalanx of the fifth digit. What is the primary action of the abductor digiti minimi? The main actions of the abductor digiti minimi are to abduct and flex the little toe, contributing to the foot's overall movement and stability. Which nerve innervates the abductor digiti minimi? The abductor digiti minimi is innervated by the lateral plantar nerve, which is a branch of the tibial nerve, providing motor function to this muscle. What is the blood supply for the abductor digiti minimi? The blood supply for the abductor digiti minimi muscle comes from the lateral plantar artery, ensuring it receives the necessary nutrients for function. Rate This Article
