Flashcards in Femoral Triangle, Adductor Canal, Vessels and Nerves of the Anterior and Medial Thigh Deck (45)
Loading flashcards...
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
