Summary
The thigh consists of the largest tubular bone (femur) of the human body and numerous muscles, which are used especially for locomotion and for standing upright. They are divided into three large groups: The thigh is connected to the trunk via the hip joint and to the lower leg via the knee joint. Various movements are also possible in these joints, but these are much less pronounced than in the arm.
The vascular supply to the thigh is provided by the main branches of the large arteries, originating from the abdominal aorta. The venous return is via the deep and superficial veins, which are connected to each other and thus transport the blood from the periphery to the trunk of the body. The nerves of the thigh originate from two large nerve plexuses: the sacral plexus and the lumbar plexus. These give off numerous larger and smaller nerves, which motorically innervate the muscles and sensitively the skin of the thigh.
