Anatomical terms of neuroanatomy

The coccygeal plexus is a small nervous plexus upon the pelvic (anterior) surface of the coccygeus muscle. [1]

Contents

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. The coccygeal plexus gives rise to the anococcygeal nerve. [2]

The coccygeal plexus is distributed to the coccygeus muscle, part of the levator ani muscle, the sacrococcygeal symphysis, and (via the anococcygeal nerve) a small area of skin between the tip of the coccyx, and the anus. [1]
