Mucus vs. Mucin

Published:

Mucusnoun

(physiology) A slippery secretion from the lining of the mucous membranes.

Mucinnoun

(biochemistry) Any of several glycoproteins found in mucus

Mucusnoun

A viscid fluid secreted by mucous membranes, which it serves to moisten and protect. It covers the lining membranes of all the cavities which open externally, such as those of the mouth, nose, lungs, intestinal canal, urinary passages, etc.

Mucinnoun

See Mucedin.

Mucusnoun

Any other animal fluid of a viscid quality, as the synovial fluid, which lubricates the cavities of the joints; - improperly so used.

Mucinnoun

Any of a class of high molecular weight glycoproteins which are contained in mucus, and give to the latter secretion its peculiar ropy character. They are found in all the secretions from mucous glands, and also between the fibers of connective tissue, as in tendons. They form viscous solutions and serve to provide lubrication for movement within body cavities, and some protection of surfaces. See Illust. of Demilune.

Mucusnoun

A gelatinous or slimy substance found in certain algæ and other plants.

Mucinnoun

a nitrogenous substance found in mucous secretions; a lubricant that protects body surfaces

Mucusnoun

protective secretion of the mucous membranes; in the gut it lubricates the passage of food and protects the epithelial cells; in the nose and throat and lungs it can make it difficult for bacteria to penetrate the body through the epithelium

Mucin

Mucins () are a family of high molecular weight, heavily glycosylated proteins (glycoconjugates) produced by epithelial tissues in most animals. Mucins' key characteristic is their ability to form gels; therefore they are a key component in most gel-like secretions, serving functions from lubrication to cell signalling to forming chemical barriers.

Mucus

Mucus ( MEW-kəs) is a slippery aqueous secretion produced by, and covering, mucous membranes. It is typically produced from cells found in mucous glands, although it may also originate from mixed glands, which contain both serous and mucous cells.
