| lateral hypothalamic area | Extends throughout most of the rostrocaudal extent of the hypothalamus lateral to the column of the fornix; includes lateral tuberal nuclei, tuberomamillary nuclei, and diffuse populations of cells. Synonym: lateral hypothalamic area. (05 Mar 2000) |

| anal region | The posterior portion of the perineal region through which the anal canal opens; bounded by a line through both isehial tuberosities, the sacrotuberous ligaments and the coccyx. Synonym: regio analis, anal region. (05 Mar 2000) |
| ankle region | The region of the lower limb between the leg (crus) and the foot (pes). Synonym: regio talocruralis. (05 Mar 2000) |
| appalachian region | A geographical area of the united states with no definite boundaries but comprising northeastern alabama, northwestern georgia, northwestern south carolina, western north carolina, eastern kentucky, eastern tennessee, western virginia, west virginia, western maryland, southwestern pennsylvania, southern ohio, and southern new york.

| axillary region | The region of the axilla, including the axillary fossa. Synonym: regio axillaris. (05 Mar 2000) |
| bay region | <chemistry> An indentation of three fused benzene rings. A common bay region is the site on benzo(a)pyrene, an indirect carcinogen that is metabolically activated by the p-450 system at the 7,8-double bond, leading to a 7,8-oxide, which is rapidly converted to a 7,8-dihydrodiol and later epoxidated near the bay region at the 9,10-double bond. The resulting product, a diol-epoxide is a poor substrate for epoxide hydratase and is released from the mitochondria into the cell as a highly reactive electrophil, becoming an ultimate carcinogen, as it reacts with negative charges in DNA. (25 Jun 1999) |
| branchial region | Region containing paired arched columns that bear gills in lower aquatic vertebrates and appear in the embryos of higher vertebrates in comparable form. In higher vertebrates the arches are subsequently modified into structures of the neck and ear. (12 Dec 1998) |

| caribbean region | The area that lies between continental north and south america and comprises the caribbean sea, the west indies, and the adjacent mainland regions of southern mexico, central america, colombia, and venezuela. (12 Dec 1998) |
| variable region | <molecular biology> Those regions in the amino acid sequence of both the heavy and the light chains of immunoglobulins where there is considerable sequence variability from one immunoglobulin to other of the same class, in contrast to constant sequence (C) regions. The V regions are associated with the antigen binding areas. They contain hypervariable regions of particularly high sequence diversity. (18 Nov 1997) |
