| 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 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.

| centrifugal nerve | <anatomy, nerve> A nerve which transmits impulses from the brain and spinal cord to a muscle or organ. (27 Sep 1997) |
| vacuum casting | The casting of a metal in the presence of a vacuum. (05 Mar 2000) |
| casting | 1. A metallic object formed in a mold. 2. The act of forming a casting in a mold. (05 Mar 2000) |
| casting flask | A metal tube in which a refractory mold is made for casting metal dental restorations or appliances. Synonym: casting flask, casting ring. (05 Mar 2000) |
| casting ring | A metal tube in which a refractory mold is made for casting metal dental restorations or appliances. Synonym: casting flask, casting ring. (05 Mar 2000) |
| casting wax | Any soft solid wax used in dentistry for patterns of all types and for many other purposes; most are basically paraffin but are modified by addition of gum dammar, carnauba wax, or other ingredients, to meet various requirements. Synonym: inlay wax. (05 Mar 2000) |
| ceramo-metal casting | A casting made of alloys containing or excluding precious metals, to which dental porcelain can be fused. (05 Mar 2000) |
| gold casting | A casting made of gold, usually formed to represent and replace lost tooth structure. (05 Mar 2000) |
| corrosion casting | A tissue preparation technique that involves the injecting of plastic (acrylates) into blood vessels or other hollow viscera and treating the tissue with a caustic substance. This results in a negative copy or a solid replica of the enclosed space of the tissue that is ready for viewing under a scanning electron microscope. (12 Dec 1998) |
| shadow-casting | Deposition of a film of carbon or certain metals such as palladium, platinum, or chromium on a contoured microscopic object in order to allow the object to be seen in relief with the electron microscope or sometimes with the light microscope. (05 Mar 2000) |
| dental casting investment | <dentistry> Material from which the casting mold is made in the fabrication of gold or cobalt-chromium castings. (boucher's clinical dental terminology, 4th ed, p168) (12 Dec 1998) |
