| elastic cone | Thicker lower portion of the elastic membrane of the larynx, extending between the cricoid cartilage and the vocal ligaments, the latter actually being a thickening of the free, superior margin of the conus elasticus. Synonym: cricovocal membrane, elastic cone. Synonym: cricothyroid ligament. (05 Mar 2000) |

| elastic fibres | Fibre's that are 0.2 to 2 um in diameter but may be larger in some ligaments; they branch and anastomose to form networks and fuse to form fenestrated membranes; the fibre's and membranes consist of microfibrils about 10 nm wide and an amorphous substance containing elastin. Synonym: yellow fibres. (05 Mar 2000) |
| elastic lamella | A thin sheet or membrane composed of elastic fibres; distinguished from elastic membrane, which usually refers to a condensed mass of fibres, as in an artery, whereas an elastic lamella may be a looser elastic layer such as found in a vein or the respiratory tract.

| elastic ligature | A rubber ligature that slowly constricts, in orthodontics, a stretchable threadlike material that may be tied from a tooth to an archwire or from tooth to tooth to gain movement of these units. (05 Mar 2000) |
| elastic limit | The greatest stress to which a material may be subjected and still be capable of returning to its original dimensions when the forces are released. (05 Mar 2000) |
| elastic membrane | A membrane formed of elastic connective tissue, present as fenestrated lamellae in the coats of the arteries and elsewhere. (05 Mar 2000) |
| elastic skin | |
| elastic tissue | A form of connective tissue in which the elastic fibres predominate; it constitutes the ligamenta flava of the vertebrae and the ligamentum nuchae, especially of quadrupeds; it occurs also in the walls of the arteries and of the bronchial tree, and connects the cartilages of the larynx. Synonym: elastica, tela elastica. (05 Mar 2000) |
| amphoteric element | An element one or more of whose oxides unite with water to form hydroxides that may act as acids or as bases (e.g., aluminum). (05 Mar 2000) |
| anatomical element | Any anatomical unit, such as a cell. Synonym: morphologic element. (05 Mar 2000) |
| vessel element | Part of a xylem vessel in a higher plant, arising from a single cell. The end walls are perforated and may completely disappear, giving rise to a continuous tube. The remaining walls are thickened and lignified and there is no protoplast. (18 Nov 1997) |
| volume element | See: voxel. (05 Mar 2000) |
| P element | <molecular biology> A class of Drosophila transposon, widely used as a vector for reporter genes, for efficient germ line transformation and for enhancer trap or insertional mutagenesis studies. (18 Nov 1997) |
