| stria medullaris thalami | A narrow, compact fibre bundle that extends along the line of attachment of the roof of the third ventricle to the thalamus on each side and terminates posteriorly in the habenular nucleus. It is composed of fibres originating in the septal area, the anterior perforated substance, the lateral preoptic nucleus, and the medial segment of the globus pallidus. Synonym: stria medullaris thalami, stria fornicis, stria ventriculi tertii. (05 Mar 2000) |

| cavitas medullaris | The marrow cavity in the shaft of a long bone. Synonym: cavitas medullaris, cavum medullare. (05 Mar 2000) |

| conus medullaris | The tapering lower extremity of the spinal cord. Synonym: conus medullaris. (05 Mar 2000) |
| substantia medullaris | The inner portion of an organ. (09 Oct 1997) |
| tubus medullaris | The ependyma-lined lumen (cavity) of the neural tube, the cerebral part of which remains patent to form the ventricles of the brain, while the spinal part in the adult often is reduced to a solid strand of modified ependyma. Synonym: canalis centralis medullae spinalis, central canal of spinal cord, tubus medullaris. Synonym: syringocele. (05 Mar 2000) |
| lamina medullaris lateralis corporis striati | A thin, sharply defined layer of fibres separating the putamen from the globus pallidus. Synonym: lamina medullaris lateralis corporis striati. (05 Mar 2000) |
| lamina medullaris medialis corporis striati | A fibre layer separating the medial and lateral segments of the globus pallidus. Synonym: lamina medullaris medialis corporis striati. (05 Mar 2000) |
| frenulum veli medullaris superioris | A band passing from the longitudinal groove between the quadrigeminal bodies on to the superior medullary velum. Synonym: frenulum veli medullaris superioris, cerebellar frenulum, frenulum cerebelli. (05 Mar 2000) |
| pedunculus thalami inferior | A large fibre bundle emerging from the anterior part of the thalamus in the ventral direction, in part joining the medial fibres of the internal capsule, in other part curving laterally around the medial margin of the capsule into the innominate substance. Many of its fibres establish a reciprocal connection of the mediodorsal nucleus of the thalamus with the orbital gyri of the frontal lobe, but numerous other fibres constitute a conduction system from the amygdala and olfactory cortex to the mediodorsal nucleus. See: ansa peduncularis. Synonym: pedunculus thalami inferior. (05 Mar 2000) |
| pedunculus thalami lateralis | The massive group of fibres that emerges from the laterodorsal side of the thalamus to join the corona radiata; it reciprocally connects the lateral nucleus and the geniculate bodies of the thalamus with the corresponding regions of the cerebral cortex. Synonym: pedunculus thalami lateralis. (05 Mar 2000) |
| pedunculus thalami ventralis | The massive system of fibre bundles emerging through the ventral, lateral, and anterior borders of the thalamus to join the internal capsule and parts of the corona radiata; it contains the fibres reciprocally connecting the ventral thalamic nuclei with the precentral and postcentral gyri of the cerebral cortex. Synonym: pedunculus thalami ventralis. (05 Mar 2000) |
| nuclei anteriores thalami | Collective term for three groups of nerve cells which together form the anterior thalamic tubercle: the anteroventral nuclei, a relatively large nucleus; the anteromedial nuclei; and the anterodorsal nuclei, a small (but large-celled) nucleus. The nuclei receive the mamillothalamic tract from the mamillary body, and additional afferents by way of the fornix; they project collectively to the cortex of the cingulate and parahippocampal gyrus. Synonym: nuclei anteriores thalami. (05 Mar 2000) |
| nuclei intralaminares thalami | Collective term denoting several cell groups embedded in the internal medullary lamina of the thalamus: central lateral nucleus, paracentral nucleus, and farthest caudally, the large centromedian nucleus. The first two of these receive afferents from the cerebral cortex, brainstem, reticular formation, cerebellum, and spinal cord, and project more or less diffusely to large regions of the frontal and parietal cortex. See: centromedian nucleus. Synonym: nuclei intralaminares thalami. (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 centralis lateralis thalami | The most lateral of the intralaminar nuclei of the thalamus. Synonym: nucleus centralis lateralis thalami. (05 Mar 2000) |
| nucleus lateralis thalami | 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) |
