Gastrocnemius |
Innervation: Tibial nerve Action: plantar flexes ankle when knee is extended, raises heel during walking, flexes leg at knee joint Function: prime mover of plantar flexion PA: Lat head: lateral aspect of lateral console of femur. Med head: popliteal surface of femur; superior to medial condylar DA: Posterior surface of Calcaneus via Calcaneal tendon |
|
|
Solelus |
PA: post aspect of head and sup quarter of post surface of the fibula; Soleil line and middle 1/3 of medial border of tibia; and tendinous arch extending btwn the bony attachments DA: post surface of the calcaneus via Calcaneal tendon NERVE: tibial nerve Action: plantarflexion of ankle independent of position of knee, steadies leg on foot Function: prime mover of plantar flexion |
|
|
Plantaris |
PA: inferior end of lateral supra condylar line of femur; oblique popliteal ligament DA: posterior surface of calcaneus via Calcaneal tendon Nerve: tibial nerve Action weakly assists gastrocnemius with plantar flexion of foot Function: synergist |
