The sacral ganglia are paravertebral ganglia of the sympathetic trunk. As the sympathetic trunk heads inferiorly down the sacrum, it turns medially. There are generally four or five sacral ganglia. In addition to gray rami communicantes, the ganglia send off sacral splanchnic nerves to join the inferior hypogastric plexus.

Near the coccyx, the right and left sympathetic trunks join to form the ganglion impar.
