| addition polymer | <chemistry> A polymer which is formed from the fusion of two monomers which join completely without losing any small molecules. (15 Jan 1998) |
|---|---|
| condensation polymer | <chemistry> The kind of polymer that is formed by the combination of monomers and the release of a small molecules at the point where monomers are joined. (05 Jan 1998) |
| polymer | <chemistry> A macromolecule made of repeating (monomer) units or protomers. (18 Nov 1997) |
| polymer fume fever | An occupational disease marked by fever, pain in the chest, and cough caused by the inhalation of fumes given off by a plastic, polytetrafluorethylene, when heated. (05 Mar 2000) |
| adipose capsule | The perirenal fat. Synonym: capsula adiposa renis, adipose capsule. (05 Mar 2000) |
| adrenal capsule | See adrenal gland. (12 Dec 1998) |
| anterior limb of internal capsule | The portion of the internal capsule between the head of the caudate nucleus and the putamen; it lies anterior to the genu of the internal capsule. Synonym: crus anterius capsulae internae. (05 Mar 2000) |
| articular capsule | A sac enclosing a joint, formed by an outer fibrous articular capsule and an inner synovial membrane. Synonym: capsula articularis, joint capsule. (05 Mar 2000) |
| atrabiliary capsule | See adrenal gland. (12 Dec 1998) |
| auditory capsule | The cartilage that, in the embryo, surrounds the developing auditory vesicle and develops into the bony labyrinth of the inner ear. (05 Mar 2000) |
| bacterial capsule | A layer of slime of variable composition which covers the surface of some bacteria; capsulated cells of pathogenic bacteria are usually more virulent than cells without capsules because the former are more resistant to phagocytic action. (05 Mar 2000) |
| Bonnet's capsule | The anterior part of the vagina bulbi. (05 Mar 2000) |
| Bowman's capsule | The expanded beginning of a nephron composed of an inner and outer layer: the visceral layer consists of podocytes which surround a tuft of capillaries (glomerulus); the parietal layer is simple squamous epithelium which becomes cuboidal at the tubular pole. Synonym: capsula glomeruli, Bowman's capsule, malpighian capsule, Muller's capsule. (05 Mar 2000) |
| capsule | <microbiology> Thick gel like material attached to the wall of gram-positive or gram-negative bacteria, giving colonies a smooth appearance. May contribute to pathogenicity by inhibiting phagocytosis. Mostly composed of very hydrophilic acidic polysaccharide, but considerable diversity exists. <pathology> Cellular response in invertebrate animals to a foreign body too large to be phagocytosed. A multicellular aggregate of haemocytes or coelomocytes isolates the foreign object. In some insects the capsule is apparently acellular and composed of melanin. (08 Oct 1997) |
| capsule cell | One of the cells located around the bodies of the cerebrospinal and sympathetic ganglionic neurons. Synonym: capsule cell. Origin: amphi-+ G. Kytos, cell (05 Mar 2000) |
