Adductor Hallucis - Podcast Version 0:00 / 0:00 1x 0.25x 0.5x 0.75x 1x 1.25x 1.5x 1.75x 2x The adductor hallucis is an intrinsic muscle of the foot. It is located within the third plantar muscle layer of the foot and has two heads – oblique and transverse. Attachments: Oblique head – originates from the bases of the 2nd, 3rd, and 4th metatarsals. Transverse head – originates from the plantar ligaments of the metatarsophalangeal joints. Both heads attach to the lateral aspect of the base of the proximal phalanx of the great toe. Actions: Adduction of the great toe. Supports the transverse arch of the foot. Innervation: Deep branch of lateral plantar nerve. Blood Supply: Medial plantar artery By TeachMeSeries Ltd (2026) Fig 4The third layer of plantar muscles.

Learn More Frequent questions What is the adductor hallucis muscle? The adductor hallucis is an intrinsic muscle located in the foot, specifically within the third plantar muscle layer. It consists of two heads, the oblique and transverse, that work together to facilitate movement. What are the attachments of the adductor hallucis? The oblique head of the adductor hallucis originates from the bases of the 2nd, 3rd, and 4th metatarsals, while the transverse head originates from the plantar ligaments of the metatarsophalangeal joints. Both heads insert on the lateral aspect of the base of the proximal phalanx of the great toe. What actions does the adductor hallucis perform? The primary action of the adductor hallucis is the adduction of the great toe. Additionally, it plays a crucial role in supporting the transverse arch of the foot. Which nerve innervates the adductor hallucis? The adductor hallucis is innervated by the deep branch of the lateral plantar nerve. This nerve provides the necessary motor function for the muscle's actions. What is the blood supply to the adductor hallucis? The blood supply to the adductor hallucis comes from the medial plantar artery. This vascular support is essential for the muscle's function and health. Rate This Article
