Extensor hallucis longus This muscle extends the first toe, dorsiflexes the ankle, and inverts the foot. Popliteus This muscle is often called "the key to the knee" because it is crucial for unlocking the knee joint at the beginning of flexion. Abductor hallucis The origin is the medial process of calcaneus and plantar aponeurosis. Quadratus plantae The nerve innervation is tibial S1, 2. Lumbricals of the foot These muscles are named after the Latin word which means "earthworm," because of their thin, elongated shape. Extensor digitorum longus The insertion is the middle and distal phalanges of second through fifth toes. Flexor digiti minimi brevis The insertion is the base of proximal phalanx of fifth toe. Adductor hallucis The nerve innervation is tibial L4, 5, S1. Fibularis brevis The insertion is the tuberosity of fifth metatarsal. Flexor digitorum longus The insertion is the distal phalanges of the second through fifth toes. Flexor hallucis brevis This muscle has two origins that are embedded with the sesamoid bones on the plantar surface of the foot. Extensor digitorum brevis The nerve innervation is Deep fibular L4, 5, S1. Flexor hallucis longus The nerve innervation is tibial L5, S1, 2. Tibialis posterior The origin is the proximal, posterior shafts of tibia and fibula; and interosseous membrane. Soleus This muscle plantarflexes the ankle. Extensor hallucis brevis The origin is the dorsal surface of calcaneus. Dorsal interossei The nerve innervation is tibial S1, 2. Abductor digiti minimi Despite its name, this muscle is stronger in flexion rather than abduction of the little toe. Flexor digitorum brevis This muscle flexes the middle phalanges of the second through fifth toes. Tibialis anterior The insertion is the medial cuneiform and base of the first metatarsal. Fibularis longus This muscle everts the foot and assists to plantar flex the ankle. Gastrocnemius The origin is the condyles of the femur, posterior surfaces. Plantaris This muscle is sometimes called the "freshman nerve" due to it often being mistakenly identified as a nerve. Plantar interossei This muscle adducts the 3rd-5th toes and flexes the 3rd-5th toes. Extensor hallucis longus This muscle extends the first toe, dorsiflexes the ankle, and inverts the foot.
