| arcuate nucleus of thalamus | 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) |

| basal nucleus 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) |
| Bechterew's nucleus | See: vestibular nucleus. Synonym: nucleus centralis tegmenti superior. (05 Mar 2000) |
| benzene nucleus | The six conjugated carbon atoms of the benzene ring. (05 Mar 2000) |
| Blumenau's nucleus | The lateral cuneate nucleus of the medulla oblongata. (05 Mar 2000) |
| body of caudate nucleus | The suprathalamic part of the caudate nucleus lying in the floor of the central part of the lateral ventricle. Synonym: corpus nuclei caudati. (05 Mar 2000) |
| Burdach's nucleus | The larger Burdach's nucleus; one of the three nuclei of the posterior column of the spinal cord; located near the dorsal surface of the medulla oblongata at and below the level of the obex, the nucleus receives posterior root fibres corresponding to the sensory innervation of the arm and hand of the same side; together with its medial companion, the gracile nucleus, it is the major source of origin of the medial lemniscus. Synonym: nucleus cuneatus, Burdach's nucleus, nucleus funiculi cuneati, nucleus of cuneate fasciculus. (05 Mar 2000) |
| gametic 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) |
| veins of caudate nucleus | Small veins from the caudate nucleus draining into the superior thalamostriate vein. Synonym: veins of caudate nucleus. (05 Mar 2000) |
| gelatinous nucleus | The soft fibrocartilage central portion of the intervertebral disk; regarded as a derivative of the notochord. Synonym: gelatinous nucleus, nucleus gelatinosus, vertebral pulp. (05 Mar 2000) |
| paracentral nucleus of thalamus | One of the intralaminar nuclei of the thalamus, medial to the central lateral nucleus. Synonym: nucleus paracentralis thalami. (05 Mar 2000) |
| ventral anterior nucleus of thalamus | The most rostral of the subdivisions of the ventral nucleus, receiving projections from the globus pallidus and projecting to the premotor and frontal cortex. Synonym: nucleus ventralis anterior thalami. (05 Mar 2000) |
| ventral intermediate nucleus of thalamus | The composite middle third of the ventral nucleus receiving in its various parts distinctive projections from the contralateral half of the cerebellum (by way of the superior cerebellar peduncle) and the ipsilateral globus pallidus; nearly all parts of the nucleus projects to the motor cortex. Synonym: nucleus ventralis intermedius thalami, nucleus ventralis lateralis, ventral lateral nucleus of thalamus. (05 Mar 2000) |
