(Print)
calcaneus via calcaneal tendon (plantar flexion)
assist flexor digitorum longus to flex 2-5 toes
medially rotate the flexed knee (tibiofemoral joint), flex the knee (T/F joint)
middle, anterior surface of fibula and interosseous membrane (dorsiflexion, inversion)
helps you stay stabilized on your foot
middle phalanges of second through fifth toes (toe flexion)
Tibial L4, 5, S1
Deep fibular L4, 5, S1
lateral condyle of the tibia; proximal, lateral surface of tibia; and interosseous membrane (inversion, dorsiflexion)
