| nucleus of lateral lemniscus | A substantial cell mass embedded in the lateral lemniscus, immediately below the latter's entry into the inferior colliculus; the nucleus represents a synaptic way-station for part of the fibres of the lateral lemniscus. Synonym: nucleus lemnisci lateralis. (05 Mar 2000) |
|---|---|
| lateral cuneate nucleus | A cell group lateral to the cuneate nucleus which receives posterior-root fibres corresponding to the proprioceptive innervation of the arm and hand; it projects to the cerebellum by way of the cuneocerebellar tract, and can be considered the upper-extremity equivalent of the thoracic nucleus. Synonym: nucleus cuneatus accessorius, external cuneate nucleus, lateral cuneate nucleus, Monakow's nucleus. (05 Mar 2000) |
| lateral nucleus of medulla oblongata | A group of cells in the medulla oblongata, located between the inferior olive and the descending trigeminal nucleus, receiving fibres from the spinal cord and motor cortex and projecting to the cerebellum. Synonym: nucleus lateralis medullae oblongatae, lateral reticular nucleus. (05 Mar 2000) |
| lateral nucleus of thalamus | The largest of the major subdivisions of the thalamus; the composite lateral nucleus includes, from before backward, the nucleus lateralis anterior or dorsalis, nucleus lateralis intermedius, nucleus lateralis posterior, and pulvinar; together, these cell groups form most of the free dorsal surface of the posterior half of the thalamus and project to a very large region of parietal, occipitoparietal, and temporal cortex; its afferent connections are largely obscure, but the nucleus lateralis posterior and the pulvinar receive a projection from the superior colliculus. Synonym: nucleus lateralis thalami. (05 Mar 2000) |
| lateral preoptic nucleus | A vaguely defined group of nerve cells in the lateral zone of the preoptic region. Synonym: nucleus preopticus lateralis. (05 Mar 2000) |
| lateral reticular nucleus | A group of cells in the medulla oblongata, located between the inferior olive and the descending trigeminal nucleus, receiving fibres from the spinal cord and motor cortex and projecting to the cerebellum. Synonym: nucleus lateralis medullae oblongatae, lateral reticular nucleus. (05 Mar 2000) |
| lateral vestibular nucleus | Nucleus vestibularis lateralis. See: vestibular nucleus. (05 Mar 2000) |
| lateral mammary branches of lateral cutaneous branches of intercostal nerves | Branches arising from the lateral cutaneous branches of the ventral primary rami of spinal nerves (intercostal nerves) T-3 to T-6 which run anteriorly to supply the lateral aspect of the breast. Synonym: rami mammarii laterales rami cutanei lateralis nervorum thoracicorum, rami mammarii laterales rami cutanei lateralis nervorum intercostalium, lateral mammary branches of lateral cutaneous branches of intercostal nerves. (05 Mar 2000) |
| lateral mammary branches of lateral cutaneous branches of thoracic spinal nerves | Branches arising from the lateral cutaneous branches of the ventral primary rami of spinal nerves (intercostal nerves) T-3 to T-6 which run anteriorly to supply the lateral aspect of the breast. Synonym: rami mammarii laterales rami cutanei lateralis nervorum thoracicorum, rami mammarii laterales rami cutanei lateralis nervorum intercostalium, lateral mammary branches of lateral cutaneous branches of intercostal nerves. (05 Mar 2000) |
| lateral mammary branches of lateral thoracic artery | <anatomy, artery> Branches of the lateral thoracic artery which extend around the lateral borders of the pectoral muscles to supply the lateral aspect of the breast and mammary gland. Synonym: rami mammarii laterales arteriae thoracicae lateralis. (05 Mar 2000) |
| lateral vein of lateral ventricle | A vein draining deep portions of the temporal and parietal lobes; it runs in the lateral wall of the lateral ventricle to terminate in the superior thalamostriate vein. Synonym: vena ventriculi lateralis lateralis, lateral atrial vein, lateral vein of lateral ventricle. (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) |
