| column chromatography | A form of partition, adsorption, ion exchange, or affinity chromatography in which one phase is liquid (aqueous) flowing down a column packed with the second phase, a solid; the dissolved substances form a partition between the solid and liquid phases depending on the chemical and physical conditions of each phase; the more strongly adsorbed solutes reach the bottom of the column later than the less strongly adsorbed ones. (05 Mar 2000) |
| column of bertin | <radiology> Partial hypertrophy of the renal cortex protruding into the renal sinus, seen on ultrasound, not pathologic--incidental finding (12 Dec 1998) |
| column of fornix | That part of the fornix that curves down in front of the thalamus and the interventricular foramen of Monro, then continues through the hypothalamus to the mamillary body; consisting primarily of fibres originating in the hippocampus and subiculum, the column of fornix is the direct continuation of the body of the fornix. Synonym: columna fornicis, anterior pillar of fornix. (05 Mar 2000) |
| column of Spitzka-Lissauer | See: dorsolateral fasciculus. (05 Mar 2000) |
| winogradsky column | <apparatus> A glass column with an anaerobic lower zone and an aerobic upper zone, which allows growth of microorganisms under conditions similar to those found in a nutrient-rich lake. (09 Oct 1997) |
| special somatic afferent column | A column of gray matter in the hindbrain of the embryo, represented in the adult by the nuclei of the auditory and vestibular nerves. (05 Mar 2000) |
| 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) |
| 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 stimulation | Electrical stimulation, either percutaneously or by direct application of electrodes to the dorsal columns of the spinal cord. (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) |
| gangliated cord | One of the two long ganglionated nerve strands alongside the vertebral column that extend from the base of the skull to the coccyx; they are connected to each spinal nerve by gray rami and receive fibres from the spinal cord through white rami connecting with the thoracic and upper lumbar spinal nerves. Synonym: truncus sympathicus, gangliated cord. (05 Mar 2000) |
| genital cord | One of a pair of mesenchymal ridges bulging into the caudal part of the celom of a young embryo and containing the mesonephric and paramesonephric duct. (05 Mar 2000) |
