| special visceral efferent column | A column of gray matter in the hindbrain of the embryo, represented in the adult by the trigeminal and facial nuclei and the nucleus ambiguus. (05 Mar 2000) |
|---|---|
| spinal column | The series of vertebrae that extend from the cranium to the coccyx, providing support and forming a flexible bony case for the spinal cord. Synonym: columna vertebralis, backbone, dorsal spine, rachis, spina dorsalis, spina, spina, spinal column, spine, vertebrarium. (05 Mar 2000) |
| Stilling's column | A column of large neurons located in the base of the posterior gray column of the spinal cord, extending from the first thoracic through the second lumbar segment; it gives rise to the dorsal spinocerebellar tract of the same side. Synonym: nucleus thoracicus, Clarke's column, Clarke's nucleus, dorsal nucleus, nucleus dorsalis, Stilling's column, Stilling's nucleus. (05 Mar 2000) |
| dorsal column of spinal cord | The pronounced, dorsolaterally oriented ridge of gray matter in each lateral half of the spinal cord, corresponding to the posterior or dorsal horn appearing in transverse sections of the cord. Synonym: columna posterior, dorsal column of spinal cord, posterior column of spinal cord. (05 Mar 2000) |
| dorsal column stimulation | Electrical stimulation, either percutaneously or by direct application of electrodes to the dorsal columns of the spinal cord. (05 Mar 2000) |
| intermediolateral cell column of spinal cord | The cell column that forms the lateral horn of the spinal cord's gray matter. Extending from the first thoracic through the second lumbar segment, the column contains the autonomic motor neurons that give rise to the preganglionic fibres of the sympathetic system. Synonym: intermediolateral cell column of spinal cord, nucleus intermediolateralis. (05 Mar 2000) |
| Turck's column | Uncrossed fibres forming a small bundle in the pyramidal tract. See: pyramidal tract. Synonym: tractus corticospinalis anterior, tractus pyramidalis anterior, anterior corticospinal tract, anterior pyramidal fasciculus, direct pyramidal tract, fasciculus corticospinalis anterior, fasciculus pyramidalis anterior, Turck's bundle, Turck's column, Turck's tract. (05 Mar 2000) |
| lateral column | A slight protrusion of the gray matter of the spinal cord into the lateral funiculus of either side, especially marked in the thoracic region where it encloses preganglionic motor neurons of the sympathetic division of the autonomic nervous system; it corresponds to the lateral horn appearing in transverse sections of the spinal cord. See: gray columns. Synonym: columna lateralis, lateral column of spinal cord. (05 Mar 2000) |

| Lissauer's column | A longitudinal bundle of thin, unmyelinated and poorly myelinated fibres capping the apex of the posterior horn of the spinal gray matter, composed of posterior root fibres and short association fibres that interconnect neighboring segments of the posterior horn. Synonym: fasciculus dorsolateralis, tractus dorsolateralis, dorsolateral tract, fasciculus marginalis, Lissauer's bundle, Lissauer's column, Lissauer's fasciculus, Lissauer's marginal zone, Lissauer's tract, marginal fasciculus, Spitzka's marginal tract, Spitzka's marginal zone, Waldeyer's tract, Waldeyer's zonal layer. (05 Mar 2000) |
| anterior intermediate groove | A furrow occasionally seen in the adult between the anterior median fissure and the anterior lateral sulcus of the spinal cord but usually present only in the foetus. It indicates the lateral border of the anterior corticospinal fasciculus. Synonym: anterior intermediate groove, sulcus intermedius anterior. (05 Mar 2000) |
| anterior intermediate sulcus | A furrow occasionally seen in the adult between the anterior median fissure and the anterior lateral sulcus of the spinal cord but usually present only in the foetus. It indicates the lateral border of the anterior corticospinal fasciculus. Synonym: anterior intermediate groove, sulcus intermedius anterior. (05 Mar 2000) |
| ganglion of intermediate nerve | The sensory ganglion of the facial (7th cranial) nerve. The geniculate ganglion cells send central processes to the brainstem and peripheral processes to the taste buds in the anterior tongue, the soft palate, and the skin of the external auditory meatus and the mastoid process. (12 Dec 1998) |
| reaction intermediate | <biochemistry> Any biomolecule which iscreated and destroyed during the course of of a particular reaction pathway. (09 Oct 1997) |
| 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) |
