Elastase: An enzyme that digests and degrades a number of proteins including elastin, an elastic substance in the lungs and some other organs that supports their structural framework. Elastase is specifically inhibited by alpha-1 antitrypsin. See also: Alpha-1 antitrypsin deficiency....
Elastase 1: Pancreatic elastase, a member of the pancreatic family of serine proteases. Although termed elastase, this powerful protease can hydrolyze numerous proteins, including elastin. The gene ELA1 that encodes elastase 1 is on chromosome 12q13....
Elastase 2: Neutrophil elastase, an enzyme in neutrophils that digests elastin. The gene ELA2 encoding elastase 2 is on chromosome 19p13,3. Mutations in ELA2 cause cyclic neutropenia, a blood disease in which there are regular cyclic fluctuations in the numbers of neutrophils and other blood cells....
Elastase inhibitor: See: Antielastase....
Elastic fiber: A slender
fiber in connective tissue that is rich in the protein elastin and has an elastic quality....
Elasticin: See: Elastin....
Elastin: A protein that coil and recoils like a spring within the elastic fibers of connective tissue and accounts for the elasticity of structures such the skin, blood vessels, heart, lungs, intestines, tendons, and ligaments. Elastin functions in connective tissue together with collagen. Whereas e...

Elbow: The juncture of the long bones in the middle portion of the arm. The bone of the upper arm (humerus) meets both the ulna (the inner bone of the forearm) and radius (the outer bone of the forearm) to form a hinge joint at the elbow. The radius and ulna also meet one another in the elbow to per...
Elbow bursitis: At the tip of the elbow (the olecranon
area), there is a bursa, a fluid-filled sac that functions as a gliding surface to reduce
friction with motion. This bursa is known as the olecranon bursa. Because of its location,
the olecranon bursa is subject to trauma, ranging from simple re...
Elbow bursitis, treatment of
Elbow bursitis, treatment of: If non-infectious, elbow
bursitis treatment includes rest, ice, and medications for inflammation and pain.
Infectious bursitis is treated with antibiotics, aspiration, and surgery....
Elbow dislocation: See: Nursemaid's elbow....
Elbow joint: Three long bones meet in the middle portion of the arm at the elbow joint. The bone of the upper arm (humerus) meets both the ulna (the inner bone of the forearm) and radius (the outer bone of the forearm) to form a hinge joint. And the radius and ulna also meet one another in the elbow...
Elbow pain: Elbow pain is most often the result of
tendinitis, which can affect the inner or outer elbow. Treatment includes ice, rest, and medication for inflammation. Elbow pain has many other causes including arthritis and bursitis. Funny bone sensation is irritation of a nerve at the elbow that...
