| 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) |
| elastica | 1. The elastic layer in the wall of an artery. Synonym: elastic tissue. (05 Mar 2000) |
| elasticin | <protein> Glycoprotein (70 kD) randomly coiled and cross linked to form elastic fibres that are found in connective tissue. Like collagen, the amino acid composition is unusual with 30% of residues being glycine and with a high proline content. Cross linking depends upon formation of desmosine from four lysine side groups. The mechanical properties of elastin are poorer in old animals. (18 Nov 1997) |
| elasticity | 1. The quality of being elastic; the inherent property in bodies by which they recover their former figure or dimensions, after the removal of external pressure or altering force; springiness; tendency to rebound; as, the elasticity of caoutchouc; the elasticity of the air. 2. Power of resistance to, or recovery from, depression or overwork. Coefficient of elasticity, the quotient of a stress (of a given kind), by the strain (of a given kind) which it produces; called also coefficient of resistance. <geometry> Surface of elasticity, the pedal surface of an ellipsoid (see Pedal); a surface used in explaining the phenomena of double refraction and their relation to the elastic force of the luminous ether in crystalline media. Origin: Cf. F. Elasticite. Source: Websters Dictionary (01 Mar 1998) |
| elasticoviscous | Alternate form of the commoner term viscoelastic. (18 Nov 1997) |

| elastofibroma | <tumour> A nonencapsulated slow-growing mass of poorly cellular, collagenous, fibrous tissue and elastic tissue; occurs usually in subscapular adipose tissue of old persons. Origin: G. Elastos, beaten, + L. Fibra, -oma tumour (05 Mar 2000) |
| elastoid degeneration | 1. Degenerative change in elastic tissue. 2. Degeneration of collagen fibres, with altered staining properties resembling elastic tissue, or formation by fibroblast-activated ultraviolet or mast cell mediators of abnormal fibres. Synonym: elastoid degeneration, elastotic degeneration. (05 Mar 2000) |
| elastoidin | A complex collagen. (05 Mar 2000) |
| elastolysis | Dissolution of elastic fibres. Origin: elasto-+ G. Lysis, loosening, fr. Luo, to loosen (05 Mar 2000) |
| elastoma | A tumour-like deposit of elastic tissue. (05 Mar 2000) |
| elastometer | A device for measuring the elasticity of any body or of the animal tissues. (05 Mar 2000) |
| elastomucin | The mucoprotein of connective tissue; e.g., elastin. (05 Mar 2000) |
