| tuber zygomaticum | Articular eminence of the temporal bone which bounds the mandibular fossa anteriorly; it forms the anterior root of the zygomatic process; it is enclosed by the articular capsule of the temporomandibular joint with the articular fossa; the head of the mandible (and intervening articular disc) move onto the articular tubercle to allow full depression of mandible (opening of mouth).

| matter, gray | The cortex of the brain which contains nerve cell bodies. The gray matter is as opposed to the white matter, the part of the brain that contains myelinated nerve fibres. The gray matter is so named because it in fact appears gray. In the mysterious affair at styles (1920), agatha christie first quoted the fictional belgian detective hercule poirot in regard to his gray matter: 'this affair must be unravelled from within.' he tapped his forehead. 'these little grey cells. It is up to them as you say over here.' (12 Dec 1998) |
| central gray substance | In general: the predominantly small-celled gray matter adjoining or surrounding the central canal of the spinal cord and the third and fourth ventricles of the brainstem, in particular: the thick sleeve of gray matter surrounding the cerebral sylvian aqueduct in the midbrain, rostrally continuous with the posterior nucleus of the hypothalamus; in sections stained for myelin it stands out from the adjoining tectum and tegmentum by the poverty of its myelinated fibres. Synonym: substantia grisea centralis. (05 Mar 2000) |
