Pudendal Plexus (nerves)
The pudendal plexus is a term used for a compound structure consisting of sacral spinal nerves. Some sources describe it as S2-S4 of the lumbosacral plexus The anterior divisions of the lumbar nerves, sacral nerves, and coccygeal nerve form the lumbosacral plexus, the first lumbar nerve being frequently joined by a branch from the twelfth thoracic.

For descriptive purposes this plexus is usually divided into three parts: * lumbar plexus * sacral plexus * pudendal plexus Injuries to the lumbosacral plexus are predominantly witnessed as bone injuries.

Coccygeal Plexus
The coccygeal plexus is a nerve plexus near the coccyx bone. Structure This plexus is formed by the ventral rami of the fourth and fifth sacral nerves, S4 & S5, and the ventral ramus of the coccygeal nerve, Co. The relative contributions of S4 and S5 are minor and major, respectively. It gives rise to the anococcygeal nerve.
