| Collier's tract | A longitudinal bundle of fibres extending from the upper border of the mesencephalon into the cervical segments of the spinal cord, located close to the midline and ventral to the central gray matter; it is composed largely of fibres from the vestibular nuclei ascending to the motor neurons innervating the external eye muscles (abducens, trochlear, and oculomotor nuclei), and descending to spinal cord segments innervating the musculature of the neck. Synonym: fasciculus longitudinalis medialis, Collier's tract, medial longitudinal bundle, posterior longitudinal bundle. (05 Mar 2000) |

| colligation | 1. A combination in which the components are distinguishable from one another. 2. The bringing of isolated events into a unified experience. Origin: L. Cum, together, + ligo, to bind (05 Mar 2000) |
| colligative | 1. Depending on numbers of particles. 2. Referring to properties of solutions that depend only on the concentration of dissolved substances and not on their nature (e.g., osmotic pressure, elevation of boiling point, vapor pressure lowering, freezing point depression). (05 Mar 2000) |
| colligative properties | <chemistry> Properties (such as freezing-point depression) of solutions that vary according to how much solute is in the solution. (09 Oct 1997) |
| collimating lens | <physics> A lens used to produce a collimated beam from a light source. With a true point source on the axis the beam would be an axial tube of parallel rays With practical sources having real area the beam will be a diverging cone of parallel rays from each light point, this beam still has special properties and can be collected again by a good lens. (05 Aug 1998) |
| collimation | <microscopy> The operation of controlling a beam of radiation so that if the light source were a point, the light rays would become parallel. The total bundle of rays diverge as the source size increases. (05 Aug 1998) |
| collimator | A device of high absorption coefficient material used in collimation. (05 Mar 2000) |
| collinearity | The phenomona that the orderings of the corresponding elements of DNA, the RNA transcribed from it, and the amino acid translated from the RNA are identical. Origin: L. Collineo, to direct in a straight line (05 Mar 2000) |
