| age-class | <ecology> A group of individuals of a species that have the same age. (09 Oct 1997) |
|---|---|
| malocclusion, angle class I | Malocclusion in which the mandible and maxilla are anteroposteriorly normal as reflected by the relationship of the first permanent molar (i.e., in neutroclusion), but in which individual teeth are abnormally related to each other. (12 Dec 1998) |
| malocclusion, angle class II | Malocclusion in which the mandible is posterior to the maxilla as reflected by the relationship of the first permanent molar (distoclusion). (12 Dec 1998) |
| malocclusion, angle class III | Malocclusion in which the mandible is anterior to the maxilla as reflected by the first relationship of the first permanent molar (mesioclusion). (12 Dec 1998) |
| genes, MHC class I | Genetic loci in the vertebrate major histocompatibility complex which encode polymorphic characteristics not related to immune responsiveness or complement activity, e.g., b loci (chicken), dla (dog), gpla (guinea pig), h-2 (mouse), rt-1 (rat), HLA-a, -b, and -c class I genes of man. (12 Dec 1998) |
| genes, MHC class II | Genetic loci in the vertebrate major histocompatibility complex that encode polymorphic products which control the immune response to specific antigens. The genes are found in the HLA-d region in humans and in the I region in mice. (12 Dec 1998) |
| MHC class II protein | <protein> The antigen-presenting molecule found primarily on macrophages and B lymphocytes. (09 Oct 1997) |
| MHC class I protein | <protein> The antigen-presenting molecule found on all nucleated vertebrate cells. (09 Oct 1997) |
| class | <biology> A taxonomic classification between division or phylum and order. (09 Oct 1997) |
| class aves | <ornithology, zoology> A biological class that is composed of all the birds (for example, penguins, pigeons, eagles, canaries, vultures, etc.) (09 Oct 1997) |
| class i | Perennial or intermittent streams that provide a source of water for domestic use. Class I streams are used by large numbers of anadromous fish or significant sports fish for spawning, rearing, or migration, or are major tributaries to other Class I streams. (05 Dec 1998) |
| class II | Perennial or intermittent streams that are used by fish for spawning, rearing, or migration. Class II streams may be tributaries to Class I streams or other Class II streams. (05 Dec 1998) |
| class III | All other perennial streams not meeting higher class criteria. (05 Dec 1998) |
| class III malocclusion | <dentistry> A Malocclusion where your lower teeth stick out past your upper teeth. This is also called an underbite. (05 Mar 2000) |
| class II malocclusion | <dentistry> A Malocclusion where your upper teeth stick out past your lower teeth. This is also called an overbite or buck teeth (05 Mar 2000) |
