| 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) |
| ventral lateral 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) |
| ventral nucleus of thalamus | A large, complex cell mass the external border of which forms the ventral and much of the lateral boundary, as well as the rostral border, of the thalamus; it can be subdivided into an anterior, intermediate, and posterior part. Synonym: nucleus ventralis thalami. (05 Mar 2000) |
| ventral nucleus of trapezoid body | A cell group embedded among the fibres of the trapezoid body, the major decussation of the central auditory pathway, in the lower pons. The nucleus receives fibres from the contralateral cochlear nuclei and contributes fibres to the ascending auditory system or lateral lemniscus. Synonym: nucleus ventralis corporis trapezoidei. (05 Mar 2000) |
| ventral posterior intermediate nucleus of thalamus | Intermediate part of the ventrobasal nuclear complex. See: ventral posterior nucleus of thalamus. Synonym: ventral posterior intermediate nucleus of thalamus. (05 Mar 2000) |
| ventral posterior nucleus of thalamus | The large posterior part of the ventral nucleus of the thalamus receiving the somatic sensory lemnisci (medial lemniscus, spinothalamic tract, trigeminal lemniscus) and the ascending gustatory (taste) lemniscus, and projecting in turn by way of the internal capsule to the cortex of the postcentral gyrus. The nucleus is somatotopically organised and subdivided into a ventral posterolateral nucleus of thalamus representing the leg, a ventral posterior intermediate nucleus of thalamus representing the arm, a ventral posteromedial nucleus of thalamus representing the face, and an arcuate nucleus of thalamus receiving the gustatory lemniscus. Synonym: nucleus ventralis posterior thalami, ventrobasal nucleus. (05 Mar 2000) |
| ventral posterolateral nucleus of thalamus | Lateral part of the ventrobasal nuclear complex. See: ventral posterior nucleus of thalamus. Synonym: nucleus ventralis posterolateralis thalami. (05 Mar 2000) |
| geniculatus lateralis nucleus | The lateral one of a pair of small oval masses that protrude slightly from the posteroinferior aspects of the thalamus; its main (dorsal) subdivision serves as a processing station in the major pathway from the retina to the cerebral cortex, receiving fibres from the optic tract and giving rise to the geniculocalcarine radiation to the visual cortex in the occipital lobe. Synonym: corpus geniculatum laterale, corpus geniculatum externum. (05 Mar 2000) |
| ventrobasal nucleus | The large posterior part of the ventral nucleus of the thalamus receiving the somatic sensory lemnisci (medial lemniscus, spinothalamic tract, trigeminal lemniscus) and the ascending gustatory (taste) lemniscus, and projecting in turn by way of the internal capsule to the cortex of the postcentral gyrus. The nucleus is somatotopically organised and subdivided into a ventral posterolateral nucleus of thalamus representing the leg, a ventral posterior intermediate nucleus of thalamus representing the arm, a ventral posteromedial nucleus of thalamus representing the face, and an arcuate nucleus of thalamus receiving the gustatory lemniscus. Synonym: nucleus ventralis posterior thalami, ventrobasal nucleus. (05 Mar 2000) |
| ventromedial hypothalamic nucleus | <anatomy> A nucleus of the middle hypothalamus, the largest cell group of the tuberal region with small-to-medium size cells. (12 Dec 1998) |
| ventromedial nucleus of hypothalamus | <anatomy> A circumscript ovoid group of small neurons in the medial zone of the tuberal region of the hypothalamus. Bilateral destruction of this nucleus in the rat leads to severe obesity. It receives numerous fibres from the amygdala via the terminal stria; its efferent connections are obscure. Synonym: nucleus ventromedialis hypothalami. (05 Mar 2000) |
| paraventricular hypothalamic nucleus | Nucleus in the anterior part of the hypothalamus. (12 Dec 1998) |
| paraventricular nucleus | A triangular group of large magnocellular neurons in the periventricular zone of the anterior half of the hypothalamus. The cells of the nucleus are similar to those of the supraoptic nucleus; the axons of about 20% of their number join in the formation of the supraopticohypophysial tract and are functionally associated with the posterior lobe of the hypophysis; they project fibres to the brainstem nuclei (dorsal motor nucleus and solitary nucleus) and to the intermediolateral cell column of the spinal cord at thoracic, lumbar, and spinal levels; similar descending autonomic fibres arise from the lateral and posterior hypothalamic nuclei. Synonym: nucleus paraventricularis, filiform nucleus, nucleus filiformis. (05 Mar 2000) |
| germ 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) |
