What is the lateral cutaneous nerve of hte thigh a branch of?

lumbosacral plexus (L2-3)

27

Where does lymph following the great saphenous vein drain into?

31

Where are the deep inguinal nodes found?

deep to the deep fascia of the thigh (fascia lata), medial to the femoral vein

32

What does the deep inguinal nodes drain into?

35

Where is the femoral canal found?

forms the medial part of the femoral sheath

36
