Lateral view of the rump with superficial (1) and middle (2) gluteal muscles transected and reflected to reveal the deep gluteal m. (3). The sciatic n. (4) runs with the caudal gluteal a. (5). Branches (6) from the sciatic n. innervate hamstring muscles, such as the reflected biceps femoris m. (7). The lumbosacral trunk (which becomes the sciatic nerve) gives off cranial gluteal nerve branches (8) that innervate middle and deep gluteal muscles and the tensor fasciae latae m. (9).

Identify: sacrotuberous ligament (10), and external anal sphincter m. (11).
