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