| centrophilin | <protein> A microtubule binding protein identified by the production of monoclonal antibodies raised against isolated centromeres. In mitotic cells centrophilin is not restricted to the centromeres, but is a major antigen of the spindle polar bodies. (18 Nov 1997) |

| centroplasm | The substance of the cytocentrum. Origin: centro-+ G. Plasma, thing formed (05 Mar 2000) |
| centrosome | <cell biology> The microtubule organising centre which, in animal cells, surrounds the centriole and which will divide to organise the two poles of the mitotic spindle. By directing the assembly of a cells skeleton, this organelle controls division, motility and shape. Origin: Gr. Soma = body (18 Nov 1997) |

| centrum medianum | 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) |

| centrum of a vertebra | The ossification centre of the central mass of the body of a vertebra, body of vertebra (as distinct from the arches). (05 Mar 2000) |
| centrum ovale | The great mass of white matter composing the interior of the cerebral hemisphere; the name refers to the general shape of this white core in horizontal sections of the hemisphere. Synonym: centrum medullare, centrum ovale, medullary centre, semioval centre, Vicq d'Azyr's centrum semiovale, Vieussens' centrum. (05 Mar 2000) |
| centrum semiovale | The great mass of white matter composing the interior of the cerebral hemisphere; the name refers to the general shape of this white core in horizontal sections of the hemisphere.

| centrum tendineum diaphragmatis | A three-lobed fibrous sheet occupying the centre of the diaphragm. Synonym: centrum tendineum diaphragmatis, trefoil tendon.
