44
Q

what is the course of the great saphenous v. and where does it drain?

A

ascends on the medial aspect of the LE, enters the saphenous hiatus to drain into the femoral v.

45
Q

what are the superficial vv. of the LE?

A

great saphenous v., accessory saphenous v., and small saphenous v.

46
Q

what is the course of the small saphenous v. and where does it drain?

A

originates and ascends on the lateral aspect of the foot and drains into the popliteal v.

47
Q

what is the origin of the ilioinguinal n.?

A

anterior divisions of lumbar plexus (L1)

48
Q

what is the course of the ilioinguinal

A

passes in cleft between internal oblique and transverse abdominus to transverse the inguinal canal

49
Q

what does the ilioinguinal n. innervate?

A

skin over femoral triangle, scrotu, (labium majora), and public symphysis

50
Q

what is the origin of the genitofemoral n.?

A

anterior divisions of lumbar plexus (L1-L2)

51
Q

what is the course of the genitofemoral n.?

A

pierces and runs on the anterior surface of psoas major.; genital branch passes through the superficial inguinal ring, femoral branch courses with femoral a. in femoral sheath

52
Q

what does the genitofemoral n. innervate?

A

genital br- cremaster m. and kin of scrotum (labia majora)

femoral br. - skin over femoral triangle

53
Q

What is the origin of the lateral femoral cutaneous n.

A

posterior division of lumbar plexus (L2-L3)

54
Q

what is the course of the lateral femoral cutaneous n.?
