Q

what is the last branch of femoral artery? what is that branches terminal branch?

A

descending genicular artery—> saphenous artery and articular branch

26
Q

what composes the posterior wall of the distal part of the adductor canal? what nerve travels along the lateral wall?

A

adductor magnus

nerve to the vasust medialis

27
Q

what artery runs between vastus intermedius and vastus lateralis and used to distinguish the two muscles?

A

lateral femoral circumflex artery

28
Q

what nerve is located between the vastus medialis and intermedius

30
Q

what fibers do each part of the adductor magnus run? what innervates each part of the muscle?

A

horizontal fibers=adductor pt, innervated by obturator

hamstring(vertical): tibial n

31
Q

the gluteus maximus covers all the heads of the posterior muscles except for which one

popliteal artery and its genicular branches
popliteal veins and its tributaries
small saphenous v

33
