Origin

The anterior root of the fifth sacral nerve originates as a series of rootlets that emerge from the ventrolateral surface of the spinal cord. These quickly merge to form the anterior root.

Course

The anterior root runs inferiorly. At lumbar and sacral levels, the anterior root descends through the vertebral column until it reaches the apex of the sacrum. Just before entering the sacral hiatus the anterior and posterior roots merge to form the spinal nerve.

Branches

There are no named branches.

Supplied Structures

The anterior root of the fifth sacral nerve has limited function. It may innervate the coccygeus muscle. Otherwise, the fifth sacral nerve is sensory.
