elasto-, elast- +

(Greek > Latin: driven on, set in motion; driven, set in motion; ductile; elasticity, elastic)

aeroelastic, aeroelasticity
1. Pertaining to, or resulting from aerodynamic forces; such as, tests to determine the aeroelastic stress on a building.
2. Deformable by aerodynamic forces; such as, distortion (as from bending) in a structure (as an airplane wing or a building) caused by aerodynamic forces.
anelasticity
1. The property of a solid in which deformation depends on the time rate of change of stress as well as on the stress itself.
2. Relating to the property of a substance in which there is no definite relation between stress and strain.
elastance
The tendency of a material to return to its original form after having been deformed; the character or quality of such a material.
elastase
A pancreatic enzyme that cleaves amino acids from proteins in the presence of trypsin (enzyme of pancreatic juice that hydrolyzes proteins into smaller polypeptide, or amino acid, units).
elastic
1. Tending to resume its initial shape after being stretched or bent.
2. A rubber band used in dental appliances.
3. Easily resuming original shape after being stretched or expanded; flexible; springy; rebounding.
4. In physics, returning to or capable of returning to an initial form or state after deformation.
5. Quick to recover, as from disappointment: "The speaker had an elastic spirit."
6. Capable of adapting to change or a variety of circumstances.
7. Etymology: coined in French about 1651 as a scientific term to describe gases, from Greek elastos, "ductile, flexible".
elastic bandage
A bandage that can be stretched on application to exert continuous local pressure.
elastic cartilage
Yellow cartilage such as is found in the epiglottis, pharynx, external ears, and auditory tube.
elastic skin
A rare condition in which there is an unusual elasticity of the skin.
elastic stocking
A stocking worn to apply pressure to the extremity, aiding the return of blood from the extremity to the heart through the deep veins.
elastic tissue
Connective tissue supplied with elastic fibers, as found in the middle layer of arteries.
elasticity
The quality or condition of being elastic; that is, the quality of returning to an original size and shape after compression or stretching.
elastin, elasticin
1. The essential constituent of yellow elastic connective tissue which is brittle when dry, but when moist is flexible and elastic.
2. An extracellular connective tissue protein that is the principal component of elastic fibers in the middle layer of arteries.

Elastin functions in connective tissue together with collagen. Whereas elastin provides elasticity, collagen provides rigidity to connective tissue. Elastin is normally no longer made after puberty and aging begins.

elastinase
An enzyme that dissolves elastin.
elastoblast
A cell that is capable of forming elastic fibers.
elastofibroma
1. A benign soft tissue tumor containing fibrous and elastic tissues which usually occurs in the subscapular region in elderly people.
2. A rare, benign, firm, unencapsulated tumor consisting of abundant sclerotic collagen mixed with thick irregular elastic fibers, usually occurring in the subscapular region in older adults and believed to be a fibrous reaction to injury.
