The inferior gluteal artery supplies oxygenated blood to the gluteus muscles and the hip joint in humans. This artery also goes down into the thigh region of the leg before branching into the ischiadic artery, also called the sciatic artery. An artery is a blood vessel that carries blood from the heart to all areas of the body. Arteries are tubular in shape and have elastic-like muscular walls that contract and expand to push the blood through the body. The Inferior gluteal artery is the smaller of the two main artery branches that stem off of the internal iliac artery that supplies blood to the entire gluteal region. This artery is named for its close proximity to the gluteus muscles. Starting at the pelvis, right below the piriformis, and passing the greater sciatic foramen, the inferior gluteal artery goes to the superior gemelli. It then spreads superiorly and branches to the gluteus maximus and other muscles. Smaller branches of the inferior gluteal artery pass medially to the skin that covers the coccyx.
