| centroacinar cell | A cell of the pancreatic ductule that occupies the lumen of an acinus; it secretes bicarbonate and water, providing an alkaline pH necessary for enzyme activity in the intestine. (05 Mar 2000) |
|---|---|
| centroblast | A lymphocyte with a large non-cleaved nucleus. Origin: centro-+ G. Blastos, germ (05 Mar 2000) |
| Centrocestus | A genus of extremely small fish-borne flukes (family Heterophyidae) that may produce intestinal lesions similar to those caused by Heterophyes heterophyes. Centrocestus formosana has been reported from man in Taiwan. Origin: G. Kentron, point, centre, + kestos, belt, both words fr. Kenteo, to pierce (05 Mar 2000) |
| centrocyte | 1. A cell whose protoplasm contains single and double granules of varying size stainable with haematoxylin; seen in lesions of lichen planus. Synonym: Lipschutz cell. 2. A lymphocyte with a small cleaved nuclei. Origin: centro-+ G. Kytos, cell (05 Mar 2000) |
| centrokinesia | Movement excited by a stimulus of central origin. Origin: centro-+ G. Kinesis, movement (05 Mar 2000) |
| centrokinetic | 1. Relating to centrokinesia. Synonym: excitomotor. (05 Mar 2000) |
| centrolecithal | Denoting an ovum in which the deutoplasm accumulates centrally. Origin: centro-+ G. Lekithos, yolk (05 Mar 2000) |
| centrolecithal egg | An egg in which the yolk is concentrated near the centre of the egg cell, as is the case in many of the insects. (05 Mar 2000) |
| centrolecithal ovum | One in which the yolk is mostly located near the centre of the egg, as in arthropods. (05 Mar 2000) |
| centromedian nucleus | A large, lentil-shaped cell group, the largest and most caudal of the intralaminar nuclei, located within the lamina medullaris interna of the thalamus between the mediodorsal nucleus and ventrobasal nucleus; so called by Luys because of its prominent appearance on frontal sections midway between the anterior and posterior pole of the human thalamus. The nucleus receives numerous fibres from the internal segment of the globus pallidus by way of the thalamic fasciculus, ansa lenticularis, and lenticular fasciculus as well as projections from area 4 of the motor cortex; its major efferent connection is with the putamen although collaterals reach broad areas of the cerebral cortex. Synonym: nucleus centromedianus, centre median de Luys, centrum medianum. (05 Mar 2000) |
| centromere | <cell biology> The region in eukaryote chromosomes where daughter chromatids are joined together. The kinetochore, to which the spindle chromosomes are attached, lies adjacent to the centromere. The centromeric DNA codes for the kinetochore. (18 Nov 1997) |
| centromere banding stain | <technique> A selective chromosome banding stain used in human cytogenetics, employing Giemsa stain after most of the DNA is denatured or extracted by treatment with alkali, acid, salt, or heat; only heterochromatic regions close to the centromeres and rich in satellite DNA stain, with the exception of the Y chromosome whose long arm usually stains throughout. Synonym: centromere banding stain. (05 Mar 2000) |
| centromeric index | The ratio of the length of the short arm of the chromosome to that of the total chromosome; ordinarily expressed as a percentage. (05 Mar 2000) |
| centromeric sequence | <molecular biology> Special sequences of DNA nucleotides found on chromosomes which provide a site for the attachment of spindle fibres during nuclear division (mitosis or meiosis). (09 Oct 1997) |
| centronuclear myopathy | Slowly progressive generalised muscle weakness and atrophy beginning in childhood; on biopsy of skeletal muscle, the nuclei of most muscle fibres are seen to be located near the centre of a small fibre (the normal position for a 10-week embryo) rather than at the periphery of the fibre; familial incidence. Autosomal dominant recessive and X-linked [310400] forms occur. Synonym: myotubular myopathy. Distal myopathy, myopathy affecting predominantly the distal portions of the limbs; onset is usually after age 40, with weakness and wasting of small muscles of the hands; The infantile form and the Swedish later-onset are autosomal dominant and there is a Japanese late-onset type that is recessive. Minicore-multicore myopathy, an uncommon nonprogressive myopathy with early onset, proximal weakness, and hypotonia. Muscle fibres show focal defects of oxidative and myofibrillar adenosine triphosphatase enzymes with disorganization of myofibril ultrastructure. Mitochondrial myopathy, weakness and hypotonia of muscles, primarily those of the neck, shoulder, and pelvic girdles, with onset in infancy or childhood; on biopsy, giant, bizarre mitochondria are seen located between muscle fibrils just beneath the sarcolemma. The dominant form is due to deletion of mitochondrial DNA and the recessive form is due to a complex deficiency. (05 Mar 2000) |

A theorem telling us that when the sample size n is sufficiently large, then the population of all possible sample means is approximately normally distributed no matter what probability distribution describes the sampled population. (page 238)
