Accompanied by its satellite vein, the caudal gluteal a. (1) runs with the sciatic nerve (2). (They exit the pelvic canal via the greater notch.) The caudal gluteal a. gives off a lateral caudal a. (3) to the tail and a dorsal perineal a. (4) to the perineum. Branches of the latter run with a caudal cutaneous femoral n. (5) from the sacral plexus and with perineal branches (6) from the pudendal n. (7).

Identify: deep gluteal m. (8), middle gluteal m. (9), superficial gluteal m. (10), sacrotuberous ligament (asterisk), anus (11) and vulva (12).
