Cervical ganglia

The cervical ganglia consist of three paravertebral ganglia:


 * superior cervical ganglion
 * middle cervical ganglion
 * inferior cervical ganglion. The inferior ganglion may be fused with the first thoracic ganglion to form a single structure, the stellate ganglion.

Nerves emerging from cervical sympathetic ganglia contribute to the cardiac plexus, among other things.
