The common carotid plexus is formed by the continuation of the external and internal carotid plexuses, with contributions from the superior cervical ganglion of the sympathetic trunk (Dorland, 2011).


As the common carotid artery ascends through the neck, the sympathetic fibers forming the plexus follow it, traveling on the surface of the common carotid artery.


There are no named branches.

Supplied Structures

The common carotid plexus supplies sympathetic efferent innervation to the glands and mucosal linings of the neck.
