Cervical ganglia The medial cervical ganglion gives rise to fibres that innervate the thyroid gland, oesophagus and trachea, and contribute to the cardiac plexus and the grey rami communicantes of spinal nerves C5–C7.
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: … inferior cervical ganglion.
Stellate ganglion is located at the level of C7, anterior to the transverse process of C7 and the neck of the first rib, superior to the cervical pleura and just below the subclavian artery….

The sympathetic ganglia, or paravertebral ganglia are autonomic ganglia, of the sympathetic nervous system. Ganglia are 20,000 to 30,000 afferent and efferent nerve cell bodies that run along on either side of the spinal cord. … The cell bodies create long sympathetic chains that are on either side of the spinal cord.
Ganglia are ovoid structures containing cell bodies of neurons and glial cells supported by connective tissue. Ganglia function like relay stations – one nerve enters and an other exits. The structure of ganglia is illustrated by the example of the spinal ganglion.
The SCG is located opposite the second and third cervical vertebrae. It lies deep to the sheath of the internal carotid artery and internal jugular vein, and anterior to the Longus capitis muscle. The SCG contains neurons that supply sympathetic innervation to a number of target organs within the head.
