31

saphenous branch of descending genicular artery

pierces vasoadductor membrane with saphenous nerve

distributes to subQ areas of upper medial portion of leg

32

femoral vein

continuation of popliteal vein superior to adductor hiatus

receives tributaries which are vena comitantes of branches of femoral artery and greater saphenous vein of femoral triangle

33

obturator artery

branch of internal iliac artery
passes from pelvic cavity to thigh via obturator canal

remains deep to obturator externus muscles

34

branches of obturator artery

anterior
posterior
acetabular

35

acetabular branch of obturator artery?

provides branches to acetabulum and an artery to the head of femur via ligamentum teres femoris

36

ligamentum teres femoris

provides acetabular branch artery to head of femur

37

anterior and posterior branches of obturator artery?

anastomose and provide branches to medial femoral muscles

38

obturator vein

parallels course of obturator artery

receives as tributaries the vena comitantes of obturator artery

is a tributary of the internal iliac vein

39

femoral nerve

ventral rami of L2,3,4
-from lumbar plexus

40

course of femoral nerve

exits pelvis deep to inguinal ligament in groove between iliacus and psoas major muscles

passes through femoral triangle lateral to femoral vessels

while in femoral triangle, provides intermediate and medial femoral cutaneous branches and motor branches to pectinus, sartorius, rectus femoris, vastus muscles, and articularis genu

41

what two branches of femoral nerve enter adductor canal?

motor branch to vastus medialis and saphenous nerve L4

does something cool?? page 249

42

obturator nerve

ventral rami of L 2,3,4
-from lumbar plexus

43

course of obturator nerve?

exits the pelvis by passing through the obturator canal, opening in obturator membrane

divides into two branches as it meets adductor brevis

44

anterior division of obturator nerve?

goes anterior to adductor brevis and deep to adductor longus

innervates adductor longus and brevis, gracilis, and sometimes the pectineus

also sends branch to hip joint an a cutaneous nerve to medial surface of thigh

45

posterior division of obturator nerve?

deep to adductor brevis on the surface of the adductor magnus

innervates obturator externus muscle and a portion of the adductor magnus

sends an articular branch to knee joint
