Document Summary

Innervation = tibial nerve or the tibial branch of the sciatic nerve. Soleus: underneath the gastrox best viewed when you take the. Gastrox out of the way: origin = both the tibia and fibula, does not cross the knee joint therefore it does not act on the knee joint, inserts on the achilles tendon. Plantaris muscle: useless because the other muscles are more powerful, almost all tendon. The muscles that go under the foot help to support the arches. All still innervated by the tibial nerve. Flexor hallicus longus: origin = tibia and fibula, runs behind the medial malleolus through the tallar shelf and attaches to the distal phalanx of digit 1, flexes digit 1. Flexor digitorum longus: flexes the digits, origin = tibia and fibula, also runs behind the medial malleolus, the tallar self and inserts onto the distal phalanx of digits 2-5. Looks at the foot and helps you identify the foot from the medial side.
