| centric jaw relation | The most retruded physiologic relation of the mandible to the maxillae to and from which the individual can make lateral movements; it is a condition which can exist at various degrees of jaw separation, and it occurs around the terminal hinge axis, the most posterior relation of the mandible to the maxillae at the established vertical relation See: eccentric relation. Synonym: median retruded relation, median relation. (05 Mar 2000) |
|---|---|
| centric occlusion | The relation of opposing occlusal surfaces which provides the maximum planned contact and/or intercuspation, the occlusion of the teeth when the mandible is in centric relation to the maxillae. Synonym: centric contact. (05 Mar 2000) |
| centric position | The position of the mandible in its most retruded unstrained relation to the maxillae. See: centric jaw relation. (05 Mar 2000) |
| centric relation | The location of the maxillary and the mandibular condyles when they are in their most posterior and superior positions in their fossae of the temporomandibular joint. (12 Dec 1998) |
| centriciput | The central portion of the upper surface of the skull, between the occiput and the sinciput. Origin: L. Centrum, centre, + caput, head (05 Mar 2000) |
| centrifugal | 1. Denoting the direction of the force pulling an object outward (away) from an axis of rotation. 2. Sometimes, by analogy, extended to describe any movement away from a centre. Compare: eccentric. Origin: L. Centrum, centre, + fugio, to flee (05 Mar 2000) |
| centrifugal casting | Casting molten metal into a mold by spinning the metal from a crucible at the end of a revolving arm. (05 Mar 2000) |
| centrifugal current | The direction of current flow in a nerve when the cathode is placed peripheral to the anode, in contrast to ascending current. Synonym: centrifugal current. (05 Mar 2000) |
| centrifugal fast analyzer | An automatic spectrophotometer that uses centrifugal force to mix samples and reagents, and propels the reactants at high speed about a detector that makes multiple absorbance readings. (05 Mar 2000) |
| centrifugal force | <physics> The apparent force which seems to pull an object outward when the object is spun around in a circle. In reality, it is the centripetal force which keeps the object rotating around in the circle when the object's inertia makes the object inclined to move in a straight tangential line away from the circle. The centrifugal force does not really exist and, in a strictly physical sense, the term is a misnomer. However, the term is useful to biologists and chemists who are using centrifuges. (13 Nov 1997) |
| centrifugal nerve | <anatomy, nerve> A nerve which transmits impulses from the brain and spinal cord to a muscle or organ. (27 Sep 1997) |
| centrifugalise | A laboratory apparatus that separates mixed samples into homogenouscomponent layers by spinning them at high speed. (09 Oct 1997) |
| centrifugalization | <procedure> The process of separating fractions of systems in a centrifuge. The most basic separation is to sediment a pellet at the bottom of the tube, leaving a supernatant at a given centrifugal force. In this case sedimentation is determined by size and density of the particles in the system amongst other factors. Density may be used as a basis for sedimentation in density gradient centrifugation. at very high g values molecules may be separated, i.e. Ultracentrifugation. In continuous centrifugation the supernatant is removed continuously as it is formed. (13 Nov 1997) |

| centimorgan |
In genetics, a centimorgan (abbreviated cM) is a unit of recombinant frequency. It is often used to imply distance along a chromosome. The centimorgan is equal to a 1% chance that a marker at one genetic locus on a chromosome will be separated from a marker at a second locus due to crossing over in a single generation. In human beings, one centimorgan is equivalent, on average, to one million base pairs. ...

| central limit theorem |
Central limit theorems are a set of weak-convergence results in probability theory. Intuitively, they all express the fact that any sum of many independent identically distributed random variables will tend to be distributed according to a particular "attractor distribution". The most important and famous result is simply called The Central Limit Theorem which states that if the summed variables have a finite variance then they will be approximately normally distributed. ...

| central pontine myelinolysis |
Central pontine myelinolysis is a neurologic disease caused by severe damage of the myelin sheath of nerve cells in the brainstem, more precisely in the area termed the pons. The most common cause is the rapid correction of low blood sodium levels (hyponatremia). Some scholars postulate that the real cause might be the lack of a substance that is essential for brain activity and is lacking due to malnutrition. ...

| censor |
A censor was a political officer of the Roman Republic. Two censors were usually elected by the Centuriate assembly every five years to serve an 18 month term. This office did not follow the usual Roman pattern of annual, one year terms, though it did follow the principle of collegiality by having two censors who served together. This office did not possess imperium and, due to this, censors were not escorted by lictors. However, to be elected as censor was considered a great honor. ...

| centrum |
Centrum (Center) is a Warsaw Metro station located under the Defilad square in the borough of Śr?mieście, right next to the Roman Dmowski rondo, where Warsaw's two main streets, Marszałkowska and Jerolimskie avenues, cross. It is very close to the Palace of Culture and Science, Warsaw Central station, Novotel Warszawa Centrum and Polonia Palace hotels. It has two levels. At the bottom one there are platforms of the Warsaw Metro Line 1. ...
