Muscles of Ankle & Toe Movement

Fibularis brevis

Smaller muscle, deep to fibularis longus; Plantar flexes and everts the foot

Fibularis longus

Superficial lateral muscle; overlies fibula; Plantar flexes and everts the foot

Tibialis anterior

Superficial muscle of the anterior leg; Prime mover of dorsiflexion; inverts foot

Gastrocnemius

Superficial muscle; has two prominent bellies that form the proximal curve of the calf; Prime mover of plantar flexion (along with soleus)

Tibialis posterior

Thick, flat muscle deep to the soleus; Prime mover of foot inversion

Extensor digitorum longus

Unipennate muscle on anterolateral surface of leg, lateral to tibalis anterior; Prime mover of toe extension

Flexor hallucis longus

Bipennate muscle; lies lateral to inferior aspect of tibialis posterior; Plantar flexes and inverts the foot; flexes the great toe at all joints

Soleus

Broad, flat muscle deep to gastrocnemius on posterior surface of calf; Prime mover of plantar flexion (along with gastrocnemius); important locomotor and postural muscle during walking and running

Flexor digitorum longus

Long narrow muscle that runs medial to and partially overlies tibialis posterior; Plantar flexes and everts the foot; prime mover of toe flexion
