| metamer | <chemistry> Any one of several metameric forms of the same substance, or of different substances having the same composition; as, xylene has three metamers, viz, orthoxylene, metaxylene, and paraxylene. See: Metamere. Source: Websters Dictionary (01 Mar 1998) |

| metamere | <biology> Unit of segmentation or metamerism. (18 Nov 1997) |
| metameric | 1. <chemistry> Having the same elements united in the same proportion by weight, and with the same molecular weight, but possessing a different structure and different properties; as, methyl ether and ethyl alcohol are metameric compounds. See Isomeric. The existence of metameric compounds is due to the different arrangement of the same constituents in the molecule. 2. <biology> Of or pertaining to a metamere or its formation; as, metameric segmentation.

| metameric nervous system | That part of the nervous system which innervates body structures developed in ontogeny from the segmentally arranged somites or, in the head region, branchial arches. The term implies reference to the neural mechanisms intrinsic to the spinal cord and brainstem (represented by the sensory nuclei, motoneuronal cell groups, and their associated interneurons in the reticular formation); by strict definition it should exclude the autonomic nervous system.

| metamerism | <biology> The condition of developing body segments (such as in earthworms). (09 Oct 1997) |

| metamerism |
A phenomenon in a scanner in which two colours that appear the same to an observer are registered as different by the scanner, or two colours that look different to an observer are accepted as identical by the scanner. Instrument metamerism is a non-recoverable error, because the input cannot be determined from the output.

| metamerism |
a metamerism occurs when the color standard and the submit do not match under all lighting conditions. This means that a solid color fabric when viewed under two different lights in a commercial light box, will appear to cast two different colors. The correct technical definition for metamerism is a conditional match that is, two or more samples match for one observer under one light source, but not under a different light source for that same observer.
