None have been found with the sympathetic ganglia associated with the branches of the trigeminal nerve.

Afferent nerve cell bodies bring information from the body to the brain and spinal cord, while efferent nerve cell ...
The superior cervical ganglion (SCG) is the upper-most and largest [1] of the cervical sympathetic ganglia of the sympathetic trunk. [1] [2] It probably formed by the union of four sympathetic ganglia of the cervical spinal nerves C1–C4.
