| lenticular process of incus | A knob at the tip of the long limb of the incus which articulates with the stapes. Synonym: processus lenticularis incudis, lenticular apophysis, lenticular bone, orbicular bone, orbicular process, orbiculare, os orbiculare, os sylvii. (05 Mar 2000) |

| lenticular progressive degeneration | <gastroenterology, neurology> An inherited (autosomal recessive) disorder where there is excessive quantities of copper in the tissues, particularly the liver and central nervous system. Wilson's disease causes the body to absorb and retain copper. The copper deposits in the liver, brain, kidneys and eyes. Complications include dementia and liver failure. Symptoms include jaundice, vomiting, tremors, weakness and slow stiff movements. Blood tests show serum ceruloplasmin is low. Medications are given to remove the excess copper from the body. Even with life-long treatment, disabling (and life-threatening) side effects are common. Inheritance: autosomal recessive. (27 Sep 1997) |
| lenticular syphilid | Eruption of flattened, dull reddish papules, 5 mm to 1 cm in diameter, occurring in secondary syphilis. Synonym: flat papular syphilid. (05 Mar 2000) |
| lenticular vesicle | In the embryo, the ectodermal invagination that forms opposite the optic cup; it is the primordium of the lens of the eye. Synonym: lenticular vesicle. (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) |
