The median sacral artery (or middle sacral artery) is a small vessel, which arises from the back of the aorta, a little above its bifurcation.
From it, minute branches are said to pass to the posterior surface of the rectum.
On the last lumbar vertebra it anastomoses with the lumbar branch of the iliolumbar artery; in front of the sacrum it anastomoses with the lateral sacral arteries, and sends offsets into the anterior sacral foramina.
