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
