The five sacral nerves emerge from the sacrum. Although the vertebral components of the sacrum are fused into a single bone, the sacral vertebrae are still used to number the sacral nerves.
- Posteriorly, they emerge from the posterior sacral foramina, and form the posterior branches of sacral nerves (including the medial clunial nerves).
- Anteriorly, they emerge from the anterior sacral foramina, and contribute to the sacral plexus (S1-S4) and coccygeal plexus.
