Abductor Hallucis - Podcast Version 0:00 / 0:00 1x 0.25x 0.5x 0.75x 1x 1.25x 1.5x 1.75x 2x The abductor hallucis 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 tubercle of the calcaneus, the flexor retinaculum and the plantar aponeurosis. It attaches to the medial base of the proximal phalanx of the great toe. Actions: Abduction and flexion of the great toe. Innervation: Medial plantar nerve (branch of the tibial nerve). Blood Supply: Medial plantar and plantar metatarsal arteries By TeachMeSeries Ltd (2026) Fig 1The first layer of plantar muscles.

Learn More Frequent questions What is the abductor hallucis muscle? The abductor hallucis is an intrinsic muscle located in the first layer of the plantar muscles of the foot. It plays a crucial role in the movement of the great toe. Where does the abductor hallucis originate from? This muscle originates from the medial tubercle of the calcaneus, the flexor retinaculum, and the plantar aponeurosis. These attachment points are essential for its function in toe movement. What actions does the abductor hallucis perform? The primary actions of the abductor hallucis are the abduction and flexion of the great toe. These movements are important for maintaining balance and proper foot mechanics. Which nerve innervates the abductor hallucis? The abductor hallucis is innervated by the medial plantar nerve, which is a branch of the tibial nerve. This innervation is vital for muscle contraction and function. What is the blood supply to the abductor hallucis? The blood supply to the abductor hallucis comes from the medial plantar and plantar metatarsal arteries. Adequate blood flow is essential for the muscle's health and performance. Rate This Article
