Document Summary

The lower limb is divided in 4 regions. The gluteal, the thigh, the leg, and the foot. The posterior of the leg goes the short saphenous vein. On the medial aspect, there is the great saphenous vein. The canal is a weak point, and the small intestine can go through. The obturator nerve (l2-l4) exits the pelvis through the obturator foramen. There are 2 divisions of the sciatic nerve. The thigh is separated in three compartments: the posterior (sciatic), anterior ( Anterior: sartorius is the longest muscle of the body. The bulk of the thigh is the quadriceps femoris which insert on the patella. The psoas major and the iliacus join together to form the iliopsoas. The pectineus was the floor of the femoris triangle. The femoral artery goes through the adductor hiatus to become the popliteal. The common fibular nerve separates into the superficial fibular nerve and the deep fibular.
