The cervical ganglia are
paravertebral ganglia
:
- superior cervical ganglion (largest) – adjacent to C2 & C3; postganglionic axon projects to target: (heart, head, neck) via "hitchhiking" on the carotid arteries
- middle cervical ganglion (smallest) – adjacent to C6; target: heart, neck
- thoracic ganglion to form a single structure, the stellate ganglion. – adjacent to C7; target: heart, lower neck, arm, posterior cranial arteries
Nerves emerging from cervical sympathetic ganglia contribute to the cardiac plexus, among other things. Unlike all other ganglia, the medial branches of the cervical ganglia are 95% postganglionic axons.
