Edinger-Westphal nucleus
Also known as:
Westphal-Edinger nucleus
Associated persons:
Ludwig Edinger
Karl Friedrich Otto Westphal
Description:
The accessory nucleus of the 3rd oculomotor nerve. It is a small group of nerve cells located just inside the oculomotor nuclei. This nucleus supplies pre-ganglionic parasympathetics to the eye, which constrict the pupil and accommodate the lens. The fibres travel in the IIIrd nerve, so damage to that nerve will also produce a dilated pupil.
Edinger first demonstrated the nucleus in the foetus in 1885, in the adult by Westphal in 1887.
