33
what is the nerve rule of the posterior compartment
tibial nerve (S1,S2)
34
gastrocnemius origin
medial and lateral epicondyles of femur 2 heads
35
gastrocnemius insertion
calcaneal tuberosity via the achille's tendon
36
gastrocnemius innervation
tibial nerve (S1,S2)
37
gastrocnemius action
talocrural joint plantarflexion knee joint flexion
38
soleus origin
