| centre median de Luys | Synonym: centromedian nucleus. Origin: Fr. (05 Mar 2000) |

| centre of ossification | The site of earliest bone formation via accumulation of osteoblasts within connective tissue (membranous ossification) or of earliest destruction of cartilage prior to onset of ossification (endochondral ossification). Synonym: punctum ossificationis, ossific centre, point of ossification. (05 Mar 2000) |
| centre of rotation | A point or line around which all other points in a body move. See: axis. (05 Mar 2000) |
| respiratory centre | The region in the medulla oblongata concerned with integrating afferent information to determine the signals to the respiratory muscles; the inspiratory and expiratory centre's considered together. (05 Mar 2000) |
| chiral centre | <chemistry> A tetrahedral carbon atom that bears four different substituents. (09 Jan 1998) |
| chondrification centre | A site of earliest cartilage formation in the body. (05 Mar 2000) |
| guiding centre | <radiobiology> Particles placed in a magnetic field will gyrate in circles around the magnetic field lines, and drift in various directions. The guiding centre represents the instantaneous centre of the circular motion. The idea is that you can think of the guiding centre as drifting, and the particle as orbiting the guiding centre. (09 Oct 1997) |
| ciliospinal centre | The preganglionic motor neurons in the first thoracic segment of the spinal cord which give rise to the sympathetic innervation of the dilator muscle of the eye's pupil. Synonym: Budge's centre. (05 Mar 2000) |
| microtubule organising centre | <cell biology> Rather amorphous region of cytoplasm from which microtubules radiate. The pattern and number of microtubules is determined by the microtubule organising centre. The pericentriolar region is the major microtubule organising centre in animal cells, the basal body of a cilium is another example. Activity of microtubule organising centres can be regulated, but the mechanism is unclear. Acronym: MTOC (18 Nov 1997) |
| microtubule-organizing centre | A locus in interphase and mitotic cells from which most microtubules radiate; in the centre of this centre is the centriole; this centre determines the polarity of cellular microtubules. (05 Mar 2000) |
| photosynthetic reaction centre, bacterial | A system consisting of proteins and cofactors which acts as a light-driven electron pump across the photosynthetic membrane of photosynthetic bacteria. (12 Dec 1998) |
| photosynthetic reaction centre, plant | A system consisting of proteins and cofactors which facilitates light energy and electron transfer in plants. (12 Dec 1998) |
| Wernicke's centre | The region of the cerebral cortex thought to be essential for understanding and formulating coherent, propositional speech; it encompasses a large region of the parietal and temporal lobes near the lateral sulcus of the left cerebral hemisphere; corresponding approximately to Brodmann's areas 40, 39, and 22. Synonym: sensory speech centre, Wernicke's area, Wernicke's field, Wernicke's region, Wernicke's zone. (05 Mar 2000) |
| community mental health centre | A mental health treatment centre located in a neighborhood catchment area close to the homes of patients, introduced in the 1960's via new federal legislation designed to replace the large state hospitals, which usually were located in remote rural areas; features include offering a series of comprehensive services by one or more members of the four mental health professions, provision of continuity of care, participation of consumers in the centres, community location to provide accessibility, a combination of indirect or preventive and direct services, the use of program-centreed as well as case-centreed consultation, a requirement for program evaluation, and various linkages to a variety of health and human services. (05 Mar 2000) |
| motor speech centre | The posterior part of the inferior frontal gyrus of the left or dominant hemisphere, corresponding approximately to Brodmann's area 44; Broca identified this region as an essential component of the motor mechanisms governing articulated speech. Synonym: Broca's area, Broca's field, motor speech centre. (05 Mar 2000) |
