Preferred Label : parvocellular oculomotor nucleus;
Uberon definition : Nucleus that is part of the oculomotor nerve complex consisting of preganglionic parasympathetic
neurons situated close to the midline at the level of the superior colliculus (Heimer,
the Human Brain and Spinal Cord, 1994, pg 244);
Uberon synonym : accessory oculomotor nucleus; Edinger-Westphal nucleus; nucleus Edinger-Westphal;
Uberon related term : Edinger-Westphal nucleus of oculomotor nerve; oculomotor nucleus, parvocellular part; oculomotor nucleus, parvicellular part;
Uberon broad term : PC3; EW;
Uberon Function note : The Edinger-Westphal nucleus supplies preganglionic parasympathetic fibers to the
eye, constricting the pupil, accommodating the lens, and convergence of the eyes.
It has also been implicated in the mirroring of pupil size in sad facial expressions[WP];
Uberon Location note : The paired nuclei are posterior to the main motor nucleus (oculomotor nucleus) and
anterolateral to the cerebral aqueduct in the rostral midbrain at the level of the
superior colliculus. It is the most rostral of the parasympathetic nuclei in the brain
stem.[WP];
