Card Set Information
lower limb wk4 blk4
When does the lower limb bud appear relative to the upper limb bud?
lower limb bud appears 2 days after the upper limb bud
How do the upper and lower limbs rotate during development?
lower limb rotates medially, upper limb rotates laterally
deep fascia of the thigh
contains saphenous opening, where great saphenous vein joins the femoral vein
deep fascia of the leg
separates into anterior, lateral, posterior
posterior compartment subdivides into superficial and deep layer
deep fascia of the ankle and foot
: superior and inferior extensor retinaculum, flexor retinaculum, superior and inferior fibular retinaculum
: dorsum has thin fascia, plantar fascia is thin over muscles and thickens centrally -> plantar aponeurosis
Branches of internal iliac
: thru greater sciatic foramen sup to piriformis
: thru greater sciatic foramen inf to piriformis
: thru obturator canal to middle thigh
becomes femoral artery below inguinal ligament
gives off profunda femoris
goes thru adductor canal to popliteal fossa, becomes popliteal artery
anterior and posterior tibial arteries given off by popliteal
posterior tibial artery gives off fibular artery

Lateral femoral cutaneous (L2-3)
Lumbosacral trunk (L4-5)
innervates iliacus muscle and pectineus muscle
all muscles of the anterior compartment of the thigh
cutaneous branches to the anterior thigh, medial leg, medial foot
thru obturator canal
innervates most muscles of medial compartment of thigh
skin on medial aspect of thigh
lateral femoral cutaneous
femoral part of genitofemoral
skin on lateral thigh
skin on upper medial thigh
skin on upper medial thigh
formed by lumbar trunk and spinal nerves S1-4
superior gluteal nerve - thru greater sciatic foramen
inferior gluteal nerve - thru greater sciatic foramen
posterior femoral cutaneous nerve - skin on posterior thigh and inf gluteal region
sciatic nerve (largest branch) - tibial nerve (posterior compartment of thigh and leg, plantar surface), common fibular nerve aka peroneal (anterior and lateral compartment of leg
: knee and middle malleolus
: web between 1st and 2nd toe
: lateral malleolus
Motor deficiencies in radiculopathy
: knee extension, hip adduction
: ankle dorsiflexion, big toe extension
: ankle plantar flexion, knee flexion, hip flexion
Which nerve innervates the medial thigh compartment?
Which nerve innervates the anterior thigh compartment?
Which nerves innervate the gluteal region?
superior and inferior gluteal nerves
Innervation to posterior thigh
Innervation to lateral compartment of the leg?
Common fibular nerve (peroneal) thru superficial fibular nerve branch
Innervation to anterior compartment of leg?
common fibular nerve (pudendal) thru deep fibular nerve branch
primary innervation to the foot?
: inguinal ligament
: adductor longus
: iliopsoas and pectineus
: tensor fascia lata
femoral VAN goes thru, great saphenous vein
: femoral artery
: femoral vein
femoral nerve not enclosed!
structures that pass thru greater sciatic foramen
sciatic nerve, inf gluteal nerve, superior gluteal nerve, pudendal nerve
superior gluteal artery/vein, inf gluteal A/V, internal pudendal A/V
structures that pass thru the lesser sciatic foramen
obturator internus tendon, pudendal nerve, internal pudendal a/v (to the perineum)
