Sacral artery

Sacral artery

The sacral arteries, as illustrated in Gray's Anatomy.

The sacral artery is a significant blood vessel in the human body, primarily responsible for supplying blood to the sacral region. It is a branch of the internal iliac artery, which is itself a major branch of the common iliac artery.

Anatomy

The sacral artery typically arises from the posterior division of the internal iliac artery. It descends towards the sacrum, giving off several branches along its course. These branches supply the muscles and skin in the sacral region, as well as the coccyx.

Clinical significance

Due to its location and function, the sacral artery can be involved in various medical conditions. For instance, injury to the sacral artery can lead to significant blood loss, given its large size and the amount of blood it carries. Additionally, blockage of the sacral artery can result in ischemia in the sacral region, which can cause pain and tissue damage.
