Coccygeal plexus

Nerve: Coccygeal plexus

Plan of sacral and pudendal plexuses.
Latin	plexus coccygeus
Gray's	subject #213 966
From	S4-S5, coccygeal nerve
To	anococcygeal nerve

The coccygeal plexus is a plexus of nerves near the coccyx bone.

Structure

This plexus is formed by the fifth sacral nerve (with a contribution from S4) and the coccygeal nerve. It gives rise to the anococcygeal nerve.
