Document Summary

Anp1106 muscles of thigh there were 3 types: lateralis, medialis, intermedius lateralis largest: site of intramuscular injection, origin linea aspera, intertrochanteric line insertion patella, tibia. Medialis forms inferomedial aspect of thigh: origin linea aspera, intertrochanteric and supracondylar line insertion patella, tibia intermedius, origin femur insertion patella, tibia. All three extend the knee and stabilize it and are innervated by the femoral nerve. Origin lateral condyle and upper 2/3 of tibial shaft, interosseous membrane. Prime mover of dorsiflexion, inverts the foot, supports the arch of the foot insertion cuneiform and metatarsal bone. Extensor digitorium longus the deep fibular nerve supply. Unipennate muscle on anterolateral surface of leg. Origin lateral condyle of tibia, proximal fibula, interosseous membrane. Prime mover of toe extension, dorsiflexes the foot insertion phalanges of the toes 2-5. Origin superior tibia, fibula and interosseous membrane. Plantar flexes the foot important during walking, running and dancing insertion calcaneous.
