The Sacral Nerves—The posterior divisions of the sacral nerves (rami posteriores) are small, and diminish in size from above downward; they emerge, except the last, through the posterior sacral foramina.

The upper three are covered at their points of exit by the Multifidus, and divide into medial and lateral branches.
