What is the hollow of the thigh?

The hollow of the thigh, often referred to as the "femoral triangle," is an anatomical region located on the anterior aspect of the thigh. It is bordered by the inguinal ligament, sartorius muscle, and adductor longus muscle. This triangular space contains important structures, including the femoral nerve, artery, and vein, as well as lymph nodes. It plays a crucial role in the vascular and nervous supply to the lower limb.
