posterior aspect of the thigh and popliteal fossa Flashcards
laoction of posterior muscles of the thigh
between gluteal fold sulcus and popliteal fossa
skin sensory innervation of posterior muscle of thigh
posterior femoral cutaneous nerve S1;S2;S3
posterior femoral cutaneous nerve passes through what to enter which region?
passes through infrapiriform foramen enters gluteal region
posterior femoral cutaneous terminates in ???
the popliteal area
supplies of P.F.C.N
buttockes and perımeum
skın covering small area of perineum
skin covering the back of thigh
skin covering popliteal fossa
small area of skin covering the upper part of the back of the leg
vein of posertior aspect of thigh
superficial veins
great long saphenous vein
posterior compartment of thigh =
hamstring compartement or flexor comp
why hamstring comp it is incompletely seprated from the medial comp ?
beacuse adductor magnus muscle shares both compartments
posterior comartment contains 3 M//
biceps femoris muscle long and short heads
semitendinosus muscles
semimebranosus muscle
muscles of posterior muscle of thigh supplied by?
branches from the sciatic nerve
blood supply of posterior aspect of the thigh ?bra
branches of the profunda femoris artery
function of postrior aspect of thigh M ?
Flexes the leg knee
extends the thigh
limb activities such as walking running and climbing
hamstring vertical head part of
the adductoe magnus
hamstring muscles should take origin ?

which artey provide a rich blood supply to posterior compartment ?
the 4th perforating branches of the profunda femoris artery
branches of sciatic nerve L1-S3 at the popliteal fossa it divides into
tibial nerve L4-S3
common peroneal nerve L4-S2
it enters the popliteal fossa
tibial nerve
