| 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 layers of arteries | elastic laminae of arteries |
| elastic layers of cornea | See: anterior limiting layer of cornea, posterior limiting layer of cornea. (05 Mar 2000) |
| 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) |
| active movement | Movement effected by the organism itself, unaided by external influences. (05 Mar 2000) |
| adversive movement | A rotation of the eyes, head, or trunk about the long axis of the body. (05 Mar 2000) |
| ameboid movement | The movement characteristic of leukocytes and protozoan organisms of the superclass Rhizopoda. See: streaming movement, filopodium, lobopodium. (05 Mar 2000) |
| amoeboid movement | <cell biology> Crawling movement of a cell brought about by the protrusion of pseudopods at the front of the cell (one or more may be seen in monopodial or polypodial amoebae, respectively). The pseudopods form distal anchorages with the surface. (05 Feb 1998) |
| assistive movement | In massage, a movement which the partially paralysed muscle of the patient would be unable to perform unaided but which is effected with the graduated assistance of the operator. (05 Mar 2000) |
