Extensor Hallucis origin and insertion
origin: Anteromedial fibula shaft and interosseous membrane; insertion: Tendon inserts on distal phalanx of great toe
Peroneus Longus action
Plantar flexes and everts foot; helps keep foot flat on ground
Peroneus Longus innervation
Superficial peroneal nerve
Peroneus Tertius origin and insertion
origin: Distal anterior surface of fibula and interosseous membrane; insertion: Tendon passes anterior to lateral malleolus and inserts on dorsum of fifth metatarsal
Extensor Hallucis action
Extends great toe; dorsiflexes foot
Extensor Hallucis innervation
Deep peroneal nerve
Extensor Digitorum Longus origin and insertion
origin: Lateral condyle and proximal ¾ of fibula; interosseous membrane; insertion: Second and third phalanges of toes 2-5 via extensor expansion
Peroneus Tertius action
Dorsiflexes and everts foot
Peroneus Tertius innervation
Deep peroneal nerve
Tibialis Anterior origin and insertion
origin: Lateral condyle and upper 2/3 of tibia; interosseous membrane; insertion: By tendon into inferior surface of medial cuneiform and first metatarsal bone
Extensor Digitorum Longus action
Dorsiflexes foot; prime mover of toe extension (acts mainly at metatarsophalangeal joints)
Extensor Digitorum Longus innervation
Deep peroneal nerve
Semimembranosus origin and insertion
origin: Ischial tuberosity; insertion: Medial condyle of tibia
Tibialis Anterior action
Prime mover of dorsiflexion; inverts foot; assists in supporting medial longitudinal arch of foot
Tibialis Anterior innervation
Deep peroneal nerve
Semitendinosus origin and insertion
origin: Ischial tuberosity in common with long head of biceps femoris; insertion: Medial aspect of upper tibial shaft
Semimembranosus action
Extends thigh and flexes knee; medially rotates leg
Semimembranosus innervation
Sciatic nerve
Biceps Femoris origin and insertion
origin: Ischial tuberosity (long head); Linea aspera and distal femur (short head); insertion: Common tendon passes downward and laterally (forming lateral border of popliteal fossa) to insert into head of fibula and lateral condyle of tibia
Semitendinosus action
Extends thigh at hip; flexes knee; with semimembranosus, medially rotates leg
Semitendinosus innervation
Sciatic nerve
Tensor Fasciae Latae origin and insertion
origin: Anterior aspect of iliac crest and anterior superior iliac spine; insertion: Iliotibial tract
Biceps Femoris action
Extends thigh and flexes knee; laterally rotates leg, especially when knee is flexed
Biceps Femoris innervation
Sciatic nerve
Vastus Intermedius origin and insertion
origin: Anterior and lateral surfaces of proximal femur shaft; insertion: As for rectus femoris
