nerves of LE Flashcards
obturator nerve
L2-L3
travels through obturator foramina
goes down toward medial aspect of thigh so sensory distribution is on skin of medial thigh and innervates medial thigh mesucles which are adductirs
femoral nerve
- think of femur
runs accross anterior aspect of femur
L2-L4
goes through inguinal canal and travels with femoral artery and veins just deep to inguinal region
goes to anterior thigh= innervates anterior thigh muscles which are primarily the quadracepts and sensory info of anterior thigh
also has branches that go all the way down medial leg and give sensory info to medial lower leg
superior gluteal nerve
travels posteriorly
runs to gluteus medius, gluteus minimus and tensor facilia
inferior gluteal nerve
more superficial
innervates gluteus maximus
sciatic nerve
largest of body
exits pelvic girdle close to sciatic notch
trvels posteriorly on posteiro thigh= innervates muscles of posterior thihg
2 upper divisions: tibular and common fibular
-tibular innervates almost all muscles of posteiror thigh except the short head of biceps femoris (which is innervated by common fibular)
moves further down and branches into common fibular and tibial nerve
common fibular nerve
arounf lateral aspect of knee and wraps around fibular head and then branches into deep fibular and superficial fibular
-deep fibular runs to anterior compartment of leg= supplies motor innervation to anterior compartment
provides some sensroy info into dorsal aspect of foot
superficial- lateral compartemtn of leg motor innervation, and dorsal and lateralaspect of foot
tibial nerve
large nerve
travels posteriorly in lower lef
innervates all posterior aspects of lower leg
so superficial and deep posterior compartments of leg
also runs around medial mallelus (bony landmark) and to plantar aspect of foot before branching to lateral and medial plantar nerve = supplies posterior leg and plantar aspect of foot
