The median sacral artery (or middle sacral artery) is a small vessel which arises posterior to the abdominal aorta superior to its bifurcation. It descends in the middle line in front of the fourth and fifth lumbar vertebræ the sacrum and coccyx and ends in the glomus coccygeum (coccygeal gland). From it minute branches pass to the posterior surface of the rectum.
