- 5: prox
- 4: mid
- 5: distal
what is the function of the arches of the foot
3 things
- assist in support of body
- absorb shock
- space for vessels/nerves/muscles
job of innerlogintudinal arch
serves for movement
what is the inner longitudinal arch composed of
- calca
- talas
- navicular
- 1st cuneiform
- 1st metatars
what is the supporting lig of the inner long arch
- plantar calcaneonavicular log
- returns arch to orginal position after being stretch
job of outer long arch
support
what side of foot is the outer long arch on?
what is it comprised of
- lateral
- calcan
- cuboid
- 5th metatars
what is the anterior metatars arch shaped by
heads of metatarsals
where is the transverse arch?
across transverse bones
-cuboid and cuneiform
what is the mortis?
made by malleoli of tib and fib
-talis sits inside of this
ligs on the lat side
5 of them
- ant tibiofibular
- pos tibiofibular
- ant talofibular
- calcaneofibular
- post talotibular
what ligs of the foot are the most easily injured
- ant talofib ***
- calcaneofibular
- post talofibular
ligs on medial side
deltoid (3 parts)
muscles of anterior compartment/main movement of these muscles
- tibialis anterior
- extensor hallicus longus
- extensor digitorum longus
- main move: doriflex
muscles making up the lateral compartment/main movement
- peroneus longus
- peroneus brevis
- peroneus tertius
- main move: eversion
what is the peroneal retinaculum
hold peroneal tendons in place at ankle
where does the sup and inf peroneal retinaculum hold the tendons
sup: behind lat malleolus
inf: below lat malleolus
what muslces are in the superficial posterior compartment
main movement
-gastrconemius
-soleus/plantaris
main move: planta flex
what muscles are in the deep posterior compartment
- tibialis posterior
- flexor hallicus longus
- flexor digitorum longs
where does the flexor retinaculum hold the tendons
behind the med malleolus
what is a bunion
thickening of bursa
