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