sacral nerve

One of five pairs of dorsal or five pairs of ventral spinal nerves originating in the sacral segments of the spinal cord.


The dorsal sacral spinal nerves innervate the skin and fascia over the sacrum and the medial gluteal region. The ventral sacral spinal nerves innervate the sacrospinous and sacrotuberous ligaments and the skin of the perineum.


The dorsal sacral spinal nerves innervate the lower multifidius muscles. The ventral sacral spinal nerves innervate the coccygeus and levator ani muscles.
