is there a major artery in your thigh
From Wikipedia, the free encyclopedia. The femoral artery (Latin: arteria femoralis) is a large artery in the thigh and the main arterial supply to the lower limb. It enters the thigh from behind the inguinal ligament as the common femoral artery, a continuation of the external iliac artery. The profunda femoris artery is a large and important branch that arises from the lateral side of the femoral artery about 1.5 in. ( 2 4 cm) below the inguinal ligament. 3  It passes medially behind the femoral vessels and enters the medial fascial compartment of the thigh.
