Anatomy & Physiology: Muscles—Abductor Hallucis.
Structure.
- Origin: calcaneus, plantar aponeurosis and flexor retinaculum.
- Insertion: medial side of proximal phalanx of great toe with the tendon of the flexor hallucis brevis.
Function.
- Concentric action: abducts and flexes great toe at metatarsophalangeal joint.
- Reverse mover action: abduction of hallux at MTP, flexion of hallux at MTP.
- Eccentric action: controls/restrains/decelerates adduction and extension of hallux at MTP.
- Isometric action: stabilization of hallux.
- Innervation: medial plantar nerve.
- Arterial supply: medial plantar artery.
