Anatomical terms of neuroanatomy |
The internal carotid plexus is a nerve plexus situated upon the lateral side of the internal carotid artery. It is composed of post-ganglionic sympathetic fibres which have synapsed at (i.e. have their nerve cell bodies at) the superior cervical ganglion. The plexus gives rise to the deep petrosal nerve.[1]
Anatomy
Postganglionic sympathetic fibres ascend from the
pupillary dilatation component of the pupillary reflex.[3] Some fibres of the plexus converge to form the deep petrosal nerve.[4]
The internal carotid plexus communicates with the
tympanic branch of the glossopharyngeal nerve.[citation needed
]
The plexus there occasionally presents a small gangliform swelling - the carotid ganglion - on the under surface of the artery.[citation needed]
