generally, regarding the thigh, muscles in the anterior compartment are innervated by the
femoral nerve
generally, regarding the thigh, muscles in the medial compartment are innervated by the
obturator nerve
generally, regarding the thigh, muscles in the posterior compartment are innervated by the
tibial portion of the sciatic nerve

internal iliac artery, through greater sciatic foramen
gluteal region arteries: inferior gluteal artery supplies (4)
gluteus maximus, obturator internus, quadratus femoris, and superior parts of the hamstrings
gluteal region arteries: internal pudendal artery arises from _, passes through the _ then the _ to enter the _
from the internal iliac artery, passes through greater and then lesser sciatic foramina to enter the perineum

gluteal region veins: superior gluteal vein and inferior gluteal vein: accompany the _ arteries
corresponding arteries
gluteal region veins: superior gluteal vein and inferior gluteal vein: drain into the
internal iliac vein
popliteal fossa: compartment _ to knee joint
posterior
popliteal fossa: bounded superolaterally by
biceps femoris
popliteal fossa: bounded superomedially by
semimembranosus
popliteal fossa: bounded inferiorly by
the 2 heads of the gastrocnemius
t/f: popliteal fossa: its floor has a larger surface than its roof
true
popliteal fossa: all important neurovascular structures that pass from the thigh to the leg do so by traversing the
popliteal fossa
popliteal fossa: nerves are most _, arteries are _, veins are _ (hint orientation superficial/deep/etc)
nerves-most superficial (posterior)
arteries-deepest
veins-in between
contents of popliteal fossa include: termination of _ vein
small saphenous vein
contents of popliteal fossa include: _ arteries and veins and their branches and tributaries
popliteal arteries and veins
contents of popliteal fossa include: 3 nerves
tibial nerve, common fibular nerve, and posterior femoral cutaneous nerve
contents of popliteal fossa include: _ nodes and _ vessels
popliteal lymph nodes (superficial and deep) and lymphatic vessels
popliteal fossa: nerves: sural nerve is formed by joining of
medial sural cutaneous nerve (derived from the tibial nerve) and sural communicating branch of the common fibular nerve
popliteal fossa: arteries: popliteal artery is the continuation of
femoral artery
popliteal fossa: arteries: popliteal artery begins at the _ an opening btwn the adductor canal and the popliteal fossa
adductor hiatus
popliteal fossa: arteries: popliteal artery gives rise to 5 anastomosing branches that supply
the joint capsule and ligaments of the knee joint
popliteal fossa: arteries: popliteal artery gives rise to what 5 anastomosing branches
1-2. superior and inferior lateral genicular arteries
3. middle genicular artery
4-5. superior and inferior medial genicular arteries
popliteal fossa: arteries: the popliteal artery’s other branches supply the (4)
hamstrings, gastrocnemius, soleus, and plantaris muscles
popliteal fossa: arteries: the popliteal artery ends by dividing into the _ artery and _ artery
anterior tibial artery and the posterior tibial artery
popliteal fossa: veins: popliteal vein is the continuation of
posterior tibial vein
popliteal fossa: veins: popliteal vein receives the _ vein
small saphenous vein
popliteal fossa: veins: popliteal vein becomes the _ vein as it traverses the adductor hiatus
femoral vein
