Cervical ganglia
The cervical ganglia are paravertebral ganglia of the sympathetic nervous system. Preganglionic nerves from the thoracic spinal cord enter into the cervical ganglions and synapse with its postganglionic fibers or nerves. The cervical ganglion has three paravertebral ganglia:superior cervical ganglion (largest) – adjacent to C2 & C3; postganglionic axon projects to target: via "hitchhiking" on the carotid arteries middle cervical ganglion (smallest) – adjacent to C6; target: heart, neck inferior cervical ganglion. The inferior ganglion may be fused with the first thoracic ganglion to form a single structure, the stellate ganglion. – adjacent to C7; target: heart, lower neck, arm, posterior cranial arteries
