| central group of axillary lymph nodes | Nodes located around the midportion of the axillary vein; they receive afferent vessels from the lateral (brachial), pectoral, and subscapular groups of axillary nodes and send efferent vessels to the apical group of axillary node's. (05 Mar 2000) |

| central gyri | The precentral and postcentral gyri. Gyri cerebri Gyri of cerebrum, the gyri or convolutions of the cerebral cortex. Cingulate gyrus, a long, curved convolution of the medial surface of the cortical hemisphere, arched over the corpus callosum from which it is separated by the deep sulcus of corpus callosum; together with the parahippocampal gyrus, with which it is continuous behind the corpus callosum, it forms the fornicate gyrus. Synonym: gyrus cinguli, callosal convolution, callosal gyrus, cingulate convolution, falciform lobe, lobus falciformis. (05 Mar 2000) |
| central illumination | axial illumination |
| central implantation | <obstetrics> Implantation in which the blastocyst remains in the uterine cavity, as in carnivores, rhesus monkeys, and rabbits. Synonym: circumferential implantation, superficial implantation. (05 Mar 2000) |
| central incisor | <dentistry> The first tooth in the maxilla and mandible on either side of the midsagittal plane of the head. (05 Mar 2000) |
| central inhibition | <physiology> Suppression or diminution of outgoing impulses from a reflex centre. (05 Mar 2000) |
| central lacteal | The blindly ending lymphatic capillary in the centre of an intestinal villus. (05 Mar 2000) |
| central limit theorem | The sum (or average) of n realizations of the same process, provided only that it has a finite variance, will approach the gaussian distribution as n becomes indefinitely large. This theory provides a broad warrant for the use of normal theory even for nongaussian data. In the form stated here, it constitutes the classical version; more general versions allow serious relaxation of the usual assumptions. (05 Mar 2000) |
| central line | <equipment> Small, flexible plastic tube inserted into the large vein above the heart, through which drugs and blood products can be given and blood samples withdrawn painlessly. Synonym: central line, Hickman catheter. (12 Jan 1998) |
| central lobule | A division of the superior vermis of the cerebellum between the lingula and the monticulus. Synonym: lobulus centralis cerebelli, central lobule. (05 Mar 2000) |
| central lobule of cerebellum | A division of the superior vermis of the cerebellum between the lingula and the monticulus. Synonym: lobulus centralis cerebelli, central lobule. (05 Mar 2000) |
| central mesenteric lymph nodes | The mesenteric lymph nodes located along the intestinal (jejunal and ileal) branches of the superior mesenteric artery. Synonym: nodi lymphatici superiores centrales, central mesenteric lymph nodes. (05 Mar 2000) |
| central metal ion | <chemistry> The metal ion to which the ligands are attached at the centre of a coordination complex. (09 Oct 1997) |
| central necrosis | Necrosis involving the deeper or inner portions of a tissue, or an organ or its units. (05 Mar 2000) |
| central nervous system | <anatomy, neurology> Pertaining to the brain, cranial nerves and spinal cord. It does not include muscles or peripheral nerves. In invertebrates, the central nervous system is composed of the segmental ganglia of the ventral nerve cord together with the fused ganglia or brain at the anterior end. Acronym: CNS (12 Jan 1998) |
