The document describes the anatomy of the thigh, including three compartments - anterior, medial, and posterior. It details the borders, contents, floor, and structures related to the femoral triangle in the anterior compartment. These include the femoral nerve, artery and vein located within the femoral sheath. The document also outlines the muscles, blood supply, and innervation of each compartment.
