caption_attribution_description: English: Caption: The muscles along the dorsal side of the foot (a) generally extend the toes while the muscles of the plantar side of the foot (b, c, d) generally flex the toes. The plantar muscles exist in three layers, providing the foot the strength to counterbalance the weight of the body. In this diagram, these three layers are shown from a plantar view beginning with the bottom-most layer just under the plantar skin of the foot (b) and ending with the top-most layer (d) located just inferior to the foot and toe bones.

context_page_description: The abductor hallucis muscle is an intrinsic muscle of the foot. It participates in the abduction and flexion of the great toe.
context_section_description: The abductor hallucis muscle is located in the medial border of the foot and contributes to form the prominence that is observed on the region. It is inserted behind on the tuberosity of the calcaneus, the flexor retinaculum, and the plantar aponeurosis. Its muscle body, relatively thick behind, flattens as it goes forward. It ends in a common tendon with the medial head of the flexor hallucis brevis that inserts on the medial surface of the base of the first proximal phalanx and its related sesamoid bone. Its medial surface is superficial and covered with the muscle's fascia and the skin.
