| nucleotoxin | A toxin acting upon the cell nuclei. (05 Mar 2000) |
|---|---|
| nucleus | The major organelle of eukaryotic cells, in which the chromosomes are separated from the cytoplasm by the nuclear envelope. (18 Nov 1997) |
| nucleus accumbens | The largest neuronal nucleus in the septal region of the diencephalon. (12 Dec 1998) |
| nucleus accumbens septi | The region of fusion between the head of the caudate nucleus and the putamen, covered on the ventral side by the olfactory tubercle. The name ("a nucleus leaning against the septum") refers to a medial, hook-shaped expansion of this anteroventral region of the striatum which curves under the floor of the frontal horn of the lateral ventricle and ascends for some distance into the ventral half of the septal region. (05 Mar 2000) |
| nucleus acusticus | An obsolete term for the combined vestibular and cochlear nuclei. (05 Mar 2000) |
| nucleus alae cinereae | The visceral motor nucleus located in the vagal trigone (ala cinerea) of the floor of the fourth ventricle. It gives rise to the parasympathetic fibres of the vagus nerve innervating the heart muscle and the smooth musculature and glands of the respiratory and intestinal tracts. Synonym: nucleus dorsalis nervi vagi, dorsal motor nucleus of vagus, dorsal nucleus of vagus, dorsal vagal nucleus, nucleus alae cinereae. (05 Mar 2000) |
| nucleus ambiguus | A very slender, longitudinal column of motor neurons in the ventrolateral medulla oblongata; its efferent fibres leave with the vagus and glossopharyngeal nerve and innervate the striated muscle fibres of the pharynx (including the musculus levator veli palatini) and the vocal cord muscles of the larynx. Synonym: ambiguous nucleus. (05 Mar 2000) |
| nucleus amygdalae | 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) |
| nucleus anterodorsalis | nucleus anterodorsalis |
| nucleus anteromedialis | nucleus anteromedialis |
| nucleus anteroventralis | nucleus anteroventralis |
| nucleus arcuatus | The small ventral region of the ventral posteromedial nucleus of thalamus in which the fibres of the gustatory lemniscus and secondary trigeminal tracts terminate; it projects to the lower part of the postcentral gyrus of the cerebral cortex. Synonym: arcuate nucleus, nucleus arcuatus thalami, nucleus arcuatus, semilunar nucleus of Flechsig, thalamic gustatory nucleus. (05 Mar 2000) |
| nucleus arcuatus thalami | The small ventral region of the ventral posteromedial nucleus of thalamus in which the fibres of the gustatory lemniscus and secondary trigeminal tracts terminate; it projects to the lower part of the postcentral gyrus of the cerebral cortex. Synonym: arcuate nucleus, nucleus arcuatus thalami, nucleus arcuatus, semilunar nucleus of Flechsig, thalamic gustatory nucleus. (05 Mar 2000) |
| nucleus basalis of Ganser | A large group of large cells in the innominate substance, ventral to the lentiform nucleus. Synonym: nucleus basalis of Ganser. (05 Mar 2000) |
| nucleus caudatus | Elongated gray mass of the neostriatum located adjacent to the lateral ventricle of the brain. (12 Dec 1998) |
