Anatomy & Physiology: Muscles—Flexor Hallucis Longus.
Structure.
- Origin: inferior 2/3 of fibula.
- Insertion: distal phalanges of great toe.
Function.
- Concentric action: ankle plantar flexion, flexion of distal and middle phalanges of toes at interphalangeal joints and proximal phalanx of each toe at metatarsophalangeal joint.
- Reverse mover action: plantarflexion; inversion/supination; flex metatarsal at MTP joint and proximal phalanx at IP.
- Eccentric action: controls/restrains/decelerates big toe atMTP and IP, and metatarsal at MTP; dorsiflexion of ankle; eversion at subtalar joint.
- Isometric action: stabilize ankle, subtalar, and MTP and IP joints.
- Innervation: tibial nerve.
- Arterial supply: posterior tibial artery.
