anatomy 5 Flashcards
What is the posterior section of sacral plexus
superior/inferio gluteal, piriformis, posterior femoral cutaneous
what is anterior section of sacral plexus
obturator internus, pudenal, quadratus femoris, levator anti
labrum
ring of acetabulum
blood supply to lumbosacral plexus
anterior iliac
Where do lower limb buds develop
L2-S2
Where do upper limb buds develop
C5-T1
Floor of femoral traingle
iliopsoas and pectineus
What is the crural fascia a continuation of
fascia lata inferior to the knee
compartment syndrome is caused by
trauma to muscles of muscles of anterior compartment
What does compartment syndrome cause
increased pressure, caused compressure of other structure of ischemia
What does injury to common peroneal nerve cause
paralysis of all anterior/lateral compartment muscles
blood supply to lateral compartment
branches of peroneal a and anterior tib a
function of lateral compartemnt
evert
functino of posterior compartment
produce plantar flexion, inversion of foot
The posterior compartment is divided into a superiorficial and deep compartment by what
transsversae intermuscular septum
nerve of posterior compartment
tibial
artery of posterior compartment
psoterior tib and peroneal a
terminal branches of peroneal a
perforting branch of peroneal
communicating a
posterior lateral malleolar a
posterior lateral calcaneal a
circumflex fib, nutrient, muscular, and communicating is all a branch of what
posterior tib
WHat does anterior tib become when it’s past the ankle
dorsalis pedis
medial sural cutaneous is a branch of
tibial n
lateral sural cutanous is a branch of
common peronal n
sural communicating nerve is a branch of
lateral sural
saphenous n
medial side of foot as far as 1st metatarsal
superfifical peroneal n
medial and intermidate dorsal cuatenous n
deep peroneal n supplies what
skin between 1st and 2nd toes
what does superficial peroneal n supply
middle part of dorsum of the foot
What are the 2 terminal branches of the dorsalis pedis
deep plantar a, and 1st dorsal metatarsal a
lateral dorsal cutanous n is a contination of waht
dural n
saphenous n is a branch of waht
femoral
termianl branch of lateral plantar a
10th proper plantar digital
first proper plantar digital a usually orignates from what
either 1st metatatsal or medial plantar a
WHat bones make up medial longitudinal arch
calcaneous, talus, navicular, 2 cuneiforms, 3 medial metatarsal
lateral longitudinal arch is made of what bones
calcaneus, cudboid, lateral 2 metatarsal
transverse arch is made of what bones
cuboid, 3 cuneifroms, bases of all metatarsals
bones that make up ankle joint

range of dorsiflexion
35 degrees
range of plantar flexion
55 degrees
when is ankle joint more unsatable, dorsiflex or plantar flex
plantar flex is more unstable
subtalar joint is also called
talocalcaneual
what type of movement does subtalar joint permit
inversion, eversion
movement permited by MP joints
flexion, extension, abduction, adduction, rotation
most common type of ankle spairan
inversion injury
inversino injury causes damge to what
lateral ligaments
potts fracture usually breaks what bones
medial, lateral malleoli and fibula
how much of the head of the femur fits into the acetabulum
1/2
pubofemoral ligament checks what movement
hyperextension, abduction, external rotation
what ligament has a spiral arrangement
ishciofemoral
function of ischiofemoral ligament
become tense during extension of femor
check hyperextension and interanl rotation
functino of ligament capitis femoris
become tense when flexed thigh is adducted
transverse acetabular lig is a continuation of what
acetabular labrum across acetabular notch
fibular collateral lig covers waht
tendon of popliteus
what crossed the tibial collateral lig
tendon of gracilis, semitendinous and sartorisus
oblique popliteal lig is an expansion of waht
tendon of semimembranous
function of ACL and PCL
stop hyperfelxion at knee
what is stronger, ACL or PCL
PCL
what causes flexion of knee
bicep femoris, semitendinosus, semimembranosus
what causes extension of knee
quadricep femoris
