| problem area wetland | <ecology> A wetland that is difficult to identify because it may lack indicators of wetland hydrology and/or hydric soils, or its dominant plant species are more common of nonwetlands. (09 Oct 1997) |

| secondary aortic area | Region of the chest at the mid-left sternal bases where aortic diastolic murmurs are often best heard. (05 Mar 2000) |
| secondary visual area | Area of the occipital lobe concerned with vision. (12 Dec 1998) |
| pulmonary area | The region of the chest at the second left intercostal space, where sounds produced at the pulmonary valve of the right ventricle are heard most distinctly. (05 Mar 2000) |
| Selected Area Electron Diffraction | <technique> In this diffraction mode an aperture is used to define the area from which a diffraction pattern is to be recorded from a thin sample. This aperture is typically located in an image plane below the sample. Selected Area Electron Diffraction patterns are simple spot patterns and are of use in phase determination (lattice spacing measurement) and defect analysis (sample orientation). Acronym: SAED (05 Aug 1998) |
| sensorimotor area | The precentral and postcentral gyri of the cerebral cortex. (05 Mar 2000) |
| septal area | The region of the cerebral hemisphere that stretches as a thin sheet of brain tissue between the fornix bundle and the ventral surface of the corpus callosum, forming the medial wall of the lateral ventricle's frontal horn; it extends ventrally through the narrow interval between the anterior commissure and the rostrum of corpus collosum as the precommissural septum or subcallosal gyrus, which is continuous caudally with the preoptic area and hypothalamus, as well as more laterally with the innominate substance; its major functional connections are with the hippocampus and hypothalamus. (05 Mar 2000) |
| silent area | Any area of the cerebrum or cerebellum in which lesions cause no definite sensory or motor symptoms. (05 Mar 2000) |
| hypothalamic area, anterior | Loose heterogeneous collection of cells in the anterior hypothalamus, continuous rostrally with the medial and lateral preoptic areas and caudally with the tuber cinereum. (12 Dec 1998) |
| hypothalamic area, lateral | An area in the middle hypothalamus continuous rostrally with the lateral preoptic area and caudally with the tegmentum mesencephali. It contains the tuberomammillary and lateral tuberal nuclei. (12 Dec 1998) |
| small-area analysis | A method of analyzing the variation in utilization of health care in small geographic or demographic areas. It often studies, for example, the usage rates for a given service or procedure in several small areas, documenting the variation among the areas. By comparing high- and low-use areas, the analysis attempts to determine whether there is a pattern to such use and to identify variables that are associated with and contribute to the variation. (12 Dec 1998) |
| somesthetic area | Somatosensory cortex, the region of the cerebral cortex receiving the somatic sensory radiation from the ventrobasal nucleus of the thalamus; it represents the primary cortical processing mechanism for sensory information originating at the body surfaces (touch) and in deeper tissues such as muscle, tendons, and joint capsules (position sense); it corresponds approximately to Brodmann's areas 1, 2, 3 on the postcentral gyrus. Synonym: somesthetic area. (05 Mar 2000) |
| species area curve | The curve on a graph produced when plotting the cumulative number of plant species found in a series of quadrats against the cumulative number or area of those quadrats, it is used to determine the number of quadrats sufficient to adequately survey the herbaceous understory. (09 Oct 1997) |
| stress-bearing area | Surfaces of structures that resist forces, strains, or pressures brought upon them during function. (05 Mar 2000) |
| striate area | Area of the occipital lobe concerned with vision. (12 Dec 1998) |
