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