gracilis
What is the action of the extensor digitorum longus?
extends 4 digits and dorsiflexes the ankle
What is the action and innervation of the plantar interossei?
I: lateral plantar nerve
What is the action of the obturator externis?
laterally rotate thigh and steadies head of femur in acetabulum
What are the boundaries of the popliteal fossa?
superolaterally- biceps femoris
superomedially- semimembranosus and semitendinosusinferolaterally/inferomedially- lateral and medial heads of gastrocnemius
What are the boundaries of the femoral triangle?
