flexor hallucis longus

the muscle that flexes the great toe. It is particularly active during the toe-off phase of walking when the body is propelled forward of the stance leg and the great toe is the last part of the foot to leave the ground. It can also contribute to plantarflexion of the foot at the ankle joint. It is innervated by the tibial nerve.

flexor hallucis longus

; FHL extrinsic foot muscle, within deep compartment of lower-leg posterior muscle group
  • origin from posterior part of fibula distal to origin of soleus; its tendon runs obliquely down lower leg passing behind medial malleolus, under sustentaculum tali and thence into third layer of sole of foot

  • insertion into plantar aspect of distal phalanx of hallux

  • nerve supply tibial nerve

  • action flexion of metatarsophalangeal and interphalangeal joints of the hallux; assisting ankle plantarflexion, especially at toe off, and during running
