Anatomical terminology

The sympathetic root of the ciliary ganglion is a part of the human anatomy that is responsible for transmitting sympathetic nervous system impulses to the eye. It originates from the internal carotid artery and terminates at the ciliary ganglion.

Structure

The sympathetic root of the ciliary ganglion is a small, delicate filament which arises from the internal carotid plexus, and, passing forward on the outer side of the internal carotid artery, enters the ciliary ganglion posteriorly.

Function

The sympathetic root of the ciliary ganglion carries sympathetic nervous system impulses to the eye. These impulses are responsible for controlling the dilation of the pupil and the smooth muscle that adjusts the shape of the lens for near and far vision.

Clinical significance

Damage to the sympathetic root of the ciliary ganglion can result in Horner's syndrome, a condition characterized by a constricted pupil, drooping eyelid, and absence of sweating on the affected side of the face.
