column

column (kol´um)

1. An anatomical part or structure in the form of a pillar or cylindric funiculus. See also fascicle. 2. A vertical object (usually cylindrical), mass, or formation.columna [NA]; [L. columna]
affinity c. affinity chromatography
anal c.'s a number of vertical ridges in the mucous membrane of the upper half of the anal canal formed as the caliber of the canal is sharply reduced from that of the rectal ampulla.columnae anales [NA] , Morgagni's c.'s, rectal c.'s;
anterior c. the pronounced, ventrally oriented ridge of gray matter in each half of the spinal cord; it corresponds to the anterior or ventral horn appearing in transverse sections of the cord, and contains the motor neurons innervating the skeletal musculature of the trunk, neck, and extremities. See also gray c.'s.columna anterior [NA];
anterior gray c. central and lateral intermediate substance
anterior c. of medulla oblongata pyramid of medulla oblongata
anterolateral c. of spinal cord lateral funiculus
Bertin's c.'s renal c.'s
branchial efferent c. a c. of gray matter in the brainstem of the embryo, represented in the adult by the nucleus ambiguus and the motor nuclei of the trigeminal and facial nerves.
Burdach's c. cuneate fasciculus
Clarke's c. thoracic nucleus
dorsal c. of spinal cord posterior c
c. 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 fibers originating in the hippocampus and subiculum, the c. of fornix is the direct continuation of the body of the fornix.columna fornicis [NA] , anterior pillar of fornix;
general somatic afferent c. in the embryo, a c. of gray matter in the hindbrain and spinal cord, represented in the adult by the sensory nuclei of the trigeminal nerve and relay cells in the dorsal horn.
general somatic efferent c. a c. of gray matter in the embryo, represented in the adult by the nuclei of the oculomotor, trochlear, abducens, and hypoglossal nerves and by motor neurons of the ventral horn of the spinal cord.
general visceral afferent c. a c. of gray matter in the hindbrain and spinal cord of the embryo, developing into the nucleus of the solitary tract and relay cells of the spinal cord.
general visceral efferent c. a c. of gray matter in the hindbrain and spinal cord of the embryo, represented in the adult by the dorsal nucleus of the vagus, the superior and inferior salivatory and Edinger-Westphal nuclei and the visceral motor neurons of the spinal cord.
Goll's c. fasciculus gracilis
Gowers' c. anterior spinocerebellar tract
gray c.'s the three somewhat ridge-shaped masses of gray matter (anterior, posterior, and lateral c.'s) that extend longitudinally through the center of each lateral half of the spinal cord; in transverse sections these c.'s appear as gray horns and are therefore commonly called ventral or anterior, dorsal or posterior, and lateral horn, respectively.columnae griseae [NA];
intermediolateral cell c. of spinal cord intermediolateral nucleus
lateral c. 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 also gray c.'s.columna lateralis [NA] , lateral c. of spinal cord;
lateral c. of spinal cord lateral c
Lissauer's c. dorsolateral fasciculus
Morgagni's c.'s anal c.'s
posterior c. 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.columna posterior [NA] , dorsal c. of spinal cord, posterior c. of spinal cord (1);
posterior c. of spinal cord 1. posterior c 2. in clinical parlance, the term often refers to the posterior funiculus of the spinal cord.
rectal c.'s anal c.'s
renal c.'s the prolongations of cortical substance separating the pyramids of the kidney.columnae renales [NA] , Bertin's c.'s;
Rolando's c. a slight ridge on either side of the medulla oblongata related to the descending trigeminal tract and nucleus.
rugal c.'s of vagina two slight longitudinal ridges, anterior and posterior, in the vaginal mucous membrane, each marked by a number of transverse mucosal folds.columnae rugarum [NA] , vaginal c.'s;
Sertoli's c.'s See Sertoli's cells, under cell.
special somatic afferent c. a c. of gray matter in the hindbrain of the embryo, represented in the adult by the nuclei of the auditory and vestibular nerves.
special visceral efferent c. a c. of gray matter in the hindbrain of the embryo, represented in the adult by the trigeminal and facial nuclei and the nucleus ambiguus.
spinal c. vertebral c
c. of Spitzka-Lissauer See dorsolateral fasciculus.
Stilling's c. thoracic nucleus
Türck's c. anterior pyramidal tract
vaginal c.'s rugal c.'s of vagina
ventral white c. white commissure
vertebral c. the series of vertebrae that extend from the cranium to the coccyx, providing support and forming a flexible bony case for the spinal cord.columna vertebralis [NA] , backbone, dorsal spine, rachis, spina dorsalis, spina (2) , spina (1) , spinal c., spine (2) , vertebrarium;
