Muscles moving the ankle joint, foot, and phalanges (Inversion, Eversion, Dorsiflexion, Plantarflexion)

Tibialis Anterior

F: Dorsiflexion at ankle, inversion of foot O: Lateral condyle and proximal shaft of tibia I: Base of first metatarsal bone and medial cuneiform

Extensor Digitorum Longus

F: Extension of toes 2-5, dorsiflexes ankle O: Lateral condyle of tibia, anterior surface of fibula I: Superior surfaces of phalanges, toes 2-5

Flexor Digitorum Longus

F: Flexor of joints of toes 2-5, plantar flexes ankle O: Posteromedial surface of tibia I: Inferior surface of distal phalanges, toes 2-5

Gastronemius

F: Plantarflexion at ankle, flexion at knee O: Femoral condyles I: Calcaneus via calcaneal tendon

Soleus

F: Plantarflexion at ankle, postural muscle when standing O: Head and proximal shaft of fibula, and adjacent posteromedial shaft of tibia I: Calcaneus via calcaneal tendon (with gastrocnemius)

Peroneus Longus (Fibularis)

F: Plantarflexion, eversion, support ankle, support longitudinal and transverse arches O: Head and proximal shaft of fibula I: Base of first metatarsal and medial cuneiform
