| ventral tegmental area | A region in the mesencephalon which is dorsomedial to the substantia nigra and ventral to the red nucleus. The mesocortical and mesolimbic dopaminergic systems originate here, including an important projection to the nucleus accumbens. Overactivity of the cells in this area has been suspected to contribute to the positive symptoms of schizophrenia. (12 Dec 1998) |

| ventral tegmental decussation | See: tegmental decussations. (05 Mar 2000) |
| ventral thalamic peduncle | The massive system of fibre bundles emerging through the ventral, lateral, and anterior borders of the thalamus to join the internal capsule and parts of the corona radiata; it contains the fibres reciprocally connecting the ventral thalamic nuclei with the precentral and postcentral gyri of the cerebral cortex. Synonym: pedunculus thalami ventralis. (05 Mar 2000) |
| ventral tier thalamic nuclei | Collective term for nuclei in the ventral part of the lateral nuclear group, e.g., ventral anterior, lateral, posterolateral, and posteromedial nuclei and the medial and lateral geniculate bodies. The basoventral nuclear complex constitutes the caudal part of the ventral tier thalamic nuclei. (05 Mar 2000) |
| ventral white column | A narrow band of white substance bordering on the anterior median fissure of the spinal cord in front of the anterior gray commissure, and consisting of nerve fibres crossing over from one half of the spinal cord to the other. Synonym: commissura alba, anterior white commissure, commissura ventralis alba, ventral white column. (05 Mar 2000) |
| lateral cutaneous branches of ventral primary ramus of thoracic spinal nerves | Branches arising in approximately the anterior axillary line at the level of the second through sixth intercostal spaces. Synonym: rami mammarii laterales nervorum intercostalium, lateral cutaneous branches of intercostal nerves. (05 Mar 2000) |
| lateral ventral hernia | Abdominal hernia through the semilunar line. Synonym: lateral ventral hernia. (05 Mar 2000) |
| acetone body | <biochemistry> Any of the three compounds created by acetyl coenzyme A (acetoacetate, hydroxybutyrate, and acetone) which are water-soluble cellular fuels normally exported by the liver. They can build up in the blood and body tissues because of starvation, untreated diabetes mellitus, or other disorders that interfere with carbohydrate metabolism. The body rids itself of ketones mainly through urine, but it rids itself of acetone through the lungs, which gives the breath a characteristic fruity odour. If ketones build up in the body long enough, they cause serious illness and coma (see ketoacidosis.) (09 Oct 1997) |
| acute inclusion body encephalitis | The most common acute encephalitis, caused by HSV-1; affects persons of any age; preferentially involves the inferomedial portions of the temporal lobe and the orbital portions of the frontal lobes; pathologically, severe haemorrhagic necrosis is present along with, in the acute stages, intranuclear eosinophilic inclusion bodies in the neurons and glial cells. Synonym: acute inclusion body encephalitis, herpes encephalitis. (05 Mar 2000) |
| adrenal body | See adrenal gland. (12 Dec 1998) |
| alveolar body | That portion of bone in either the maxilla or the mandible which surrounds and supports the teeth. (12 Dec 1998) |
| amygdaloid body | Almond-shaped group of basal nuclei anterior to the inferior horn of the lateral ventricle of the brain, within the temporal lobe. The amygdala is part of the limbic system. (12 Dec 1998) |
| amylogenic body | A plant plastid involved in the synthesis and storage of starch. Found in many cell types, but particularly storage tissues. Characteristically has starch grains in the plastid stroma. (18 Nov 1997) |
| anococcygeal body | <anatomy> A musculofibrous band that passes between the anus and the coccyx. Synonym: ligamentum anococcygeum, anococcygeal body, raphe anococcygea, Symington's anococcygeal body. (05 Mar 2000) |
| anterior quadrigeminal body | The paired, larger, rounded anterior eminence of the laminae of mesencephalic tectum; major afferent connections of the superficial layers are the retina and striate cortex; input to deep layers of the colliculus are polymodal. Its efferent connections are with the lower brainstem and spinal cord (tectobulbar tract and tectospinal tract) and with the pulvinar and other cell groups in the caudal part of the thalamus; participates in extrageniculate visual pathway. Synonym: colliculus superior, anterior quadrigeminal body, corpus quadrigeminum anterius. (05 Mar 2000) |
