27
Identify this green muscle.
(medial thigh: adductor) **PECTINEUS** ori: superior pubic ramus ins: pectineal line of femur inn: femoral n act: adduct leg

31
What runs through the adductor hiatus?
the femoral a to feed to posterial popliteal fossa
32
Explain the venous drainage of the lower limb.
Vein gives off femoral vein and popliteal vein 1. Femoral vein run medial anterior = great saphenous vein Runs medial anterior of leg down to dorsal venous arch runs back up medial posterior leg= small saphenous vein 2. popliteal vein runs anterior medial thigh and meets with small saphenous vein
33
Explain the lymphatic drainage of the lower limb
1. popliteal lymph nodes: responsible for posterior 2. superficial inguinal lymph nodes: anterior and medial
34
What is found in the femoral triangle? What are the borders of the femoral triangle? base?
Femoral triangle: femoral V.A.N. superior border: inguinal ligmament medial border: adductor longus lateral border: sartorius base: ilipsoas & pectineus
35
