(Print)
plantar flex the ankle (talocrural joint)
keeps your toes from dragging while you walk
it lifts your foot and your toes at the same time
medially rotate the flexed knee (tibiofemoral joint), flex the knee (T/F joint)
helps you stay stabilized on your foot
lateral condyle of the tibia; proximal, lateral surface of tibia; and interosseous membrane (inversion, dorsiflexion)
the key for maintaining the transverse arch of your foot
tibial L5, S1, (2) (plantar flexion, inversion)
it acts like a mini hand gripping the ground
abduct 2-4 toes, flex 2-4 toes (metatarsophalangeal joint)
proximal, posterior shafts of tibia and fibula; and interosseous membrane (inversion, plantar flexion)
Deep fibular L4, 5, S1
middle, anterior surface of fibula and interosseous membrane (dorsiflexion, inversion)
assist flexor digitorum longus to flex 2-5 toes
evert the foot, assist to plantar flex the ankle (talocrural joint)
adjacent surfaces of all metatarsals
Tibial L4, 5, S1
calcaneus via calcaneal tendon
first: tibial L4, 5, S1
2-4: Tibial L(4), (5), S1, 2
proximal, posterior aspect of tibia
Flex first toe, weak plantar flexion of ankle, invert the foot
Tibial L4, 5, S1 (toe flexion)
middle phalanges of second through fifth toes (toe flexion)
dorsal surface of calcaneus (toe extension)
head of fibula and proximal two-thirds of lateral fibula (eversion)
one of the few muscles that crosses two joints
medial surfaces of 3-5 metatarsals (toe flexion)
Tibial L4, 5, S1
calcaneus via calcaneal tendon (plantar flexion)
