| lens capsule | The capsule enclosing the lens of the eye. Synonym: capsula lentis, crystalline capsule, lenticular capsule, phacocyst. (05 Mar 2000) |
|---|---|
| lens capsule, crystalline | The noncellular outer covering of the crystalline lens, secreted by the embryonic anterior and posterior epithelium. The embryonic posterior epithelium later disappears. (12 Dec 1998) |
| posterior limb of internal capsule | That subdivision of the internal capsule caudal to the genu between the thalamus and lentiform nucleus. Synonym: crus posterius capsulae internae. (05 Mar 2000) |
| posterior pole of lens | The central point on the posterior surface of the lens. Synonym: polus posterior lentis. (05 Mar 2000) |
| posterior surface of lens | The posterior surface of the lens of the eye. Synonym: facies posterior lentis. (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) |
