| gigantocellular nucleus of medulla oblongata | One of the three major nuclei of the reticular formation of the brainstem. Synonym: nucleus gigantocellularis medullae oblongatae. (05 Mar 2000) |
|---|---|
| reduction nucleus | A nucleus that degenerates in the cell during the changes incident to fertilization. (05 Mar 2000) |
| caudate nucleus | Elongated gray mass of the neostriatum located adjacent to the lateral ventricle of the brain. (12 Dec 1998) |
| globosus nucleus | A group of two or three small masses of gray substance in the white central core of the cerebellum, medial to the emboliform nucleus; receives axons of Purkinje cells of the intermediate area of the cerebellar cortex; axons of these cells exit the cerebellum via the superior cerebellar peduncle. Synonym: nucleus globosus, spherical nucleus. (05 Mar 2000) |
| medial accessory olivary nucleus | A detached part of the olivary nucleus medial to the latter's main body, against the lateral side of the medial lemniscus and pyramidal tract. Synonym: nucleus olivaris accessorius medialis. (05 Mar 2000) |
| medial preoptic nucleus | A group of nerve cells forming the medial zone of the preoptic region. Synonym: nucleus preopticus medialis. (05 Mar 2000) |
| medial vestibular nucleus | Nucleus vestibularis medialis. See: vestibular nucleus. (05 Mar 2000) |
| cell nucleus | Within a eukaryotic cell, a membrane-limited body which contains chromosomes and one or more nucleoli (cell nucleolus). The nuclear membrane consists of a double unit-type membrane which is perforated by a number of pores; the outermost membrane is continuous with the endoplasmic reticulum. A cell may contain more than one nucleus. (12 Dec 1998) |
| reproductive nucleus | <cell biology> The smaller nucleus in ciliate protozoans, fully active in inheritance and passed after meiosis to conjugating pairs. Gives rise to the macronucleus or macronuclei. Genes in the micronucleus are not actively transcribed. (18 Nov 1997) |
| mediodorsal nucleus | A large, composite cell group in the dorsomedial region of the thalamus having reciprocal connections with the entire extent of the frontal cortex anterior to the motor cortex (area 4) and premotor cortex (area 6). The afferent connections of the medial nucleus also include projections from the olfactory cortex and amygdala. Synonym: nucleus medialis thalami, dorsomedial nucleus, mediodorsal nucleus. (05 Mar 2000) |
| centromedian nucleus | A large, lentil-shaped cell group, the largest and most caudal of the intralaminar nuclei, located within the lamina medullaris interna of the thalamus between the mediodorsal nucleus and ventrobasal nucleus; so called by Luys because of its prominent appearance on frontal sections midway between the anterior and posterior pole of the human thalamus. The nucleus receives numerous fibres from the internal segment of the globus pallidus by way of the thalamic fasciculus, ansa lenticularis, and lenticular fasciculus as well as projections from area 4 of the motor cortex; its major efferent connection is with the putamen although collaterals reach broad areas of the cerebral cortex. Synonym: nucleus centromedianus, centre median de Luys, centrum medianum. (05 Mar 2000) |
| ceruleus nucleus | A widely used term designating the locus ceruleus. See: locus ceruleus. (05 Mar 2000) |
| gonad nucleus | <cell biology> The smaller nucleus in ciliate protozoans, fully active in inheritance and passed after meiosis to conjugating pairs. Gives rise to the macronucleus or macronuclei. Genes in the micronucleus are not actively transcribed. (18 Nov 1997) |
| gracile nucleus | The medial one of the three nuclei of the dorsal column, the remaining two being the cuneate nucleus and the accessory cuneate nucleus, which corresponds to the clava; it receives dorsal-root fibres conveying sensory innervation of the leg, and lower trunk, and projects, by way of the medial lemniscus, to the ventral nucleus posterior nucleus of the thalamus. Synonym: nucleus gracilis, nucleus fasciculi gracilis, nucleus funiculi gracilis, nucleus of Goll. (05 Mar 2000) |
| mesencephalic nucleus of trigeminal nerve | <anatomy, nerve> A long, narrow plate of unipolar neurons extending throughout the length of the midbrain, in and along the lateral angle of the central gray substance. The nucleus is the single known instance of primary sensory neurons enclosed in the central nervous system instead of in a peripheral sensory ganglion. Its peripheral axonal processes pass with the trigeminal nerve, give collaterals to the trigeminal motor nucleus, and terminate in the muscles of mastication. Synonym: nucleus tractus mesencephali nervi trigemini. (05 Mar 2000) |
