| extreme capsule | The layer of white matter separating the claustrum from the cortex of the insula, probably representing largely corticopetal and corticofugal fibres of the insular cortex. Synonym: capsula extrema. (05 Mar 2000) |
|---|---|
| eye capsule | A condensation of connective tissue on the outer aspect of the sclera from which it is separated by a narrow cleftlike episcleral space; the sheath is attached to the sclera near the sclerocorneal junction and blends with the fascia of the extraocular muscles. Synonym: vagina bulbi, capsula bulbi, eye capsule, fascia bulbi, sheath of eyeball, Tenon's capsule, vagina oculi. (05 Mar 2000) |
| fatty renal capsule | The perirenal fat. Synonym: capsula adiposa renis, adipose capsule. (05 Mar 2000) |
| 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) |
| lenticular capsule | The capsule enclosing the lens of the eye. Synonym: capsula lentis, crystalline capsule, lenticular capsule, phacocyst. (05 Mar 2000) |
| annular part of fibrous digital sheath | One of the two circular fibrous bands of the fibrous sheaths of the fingers and toes attached to the shaft of the proximal and middle phalanges. Synonym: pars annularis vaginae fibrosae, annular pulley, annulus of fibrous sheath, ligamentum annulare digitorum. (05 Mar 2000) |
| annulus of fibrous sheath | One of the two circular fibrous bands of the fibrous sheaths of the fingers and toes attached to the shaft of the proximal and middle phalanges. Synonym: pars annularis vaginae fibrosae, annular pulley, annulus of fibrous sheath, ligamentum annulare digitorum. (05 Mar 2000) |
| cardiac fibrous skeleton | A complex framework of dense collagen forming four fibrous rings (annuli fibrosi), which surround the ostia of the valves, a right and left fibrous trigone, formed by connecting the rings, and the membranous portions of the interatrial and interventricular septa; it is found in association with the base of the ventricles, i.e., at the level of the coronary sulcus; its functions include: 1) contributing reinforcement of the valvular ostia while providing attachment for the leaflets and cusps of the valves; 2) providing origin and insertion for the myocardium; and 3) serving as a sort of electrical "insulator," separating the electrically conducted impulses of the atria and ventricles and providing passage for the common atrioventricular bundle of conductive tissue through the right fibrous trigone and membranous interventricular septum. Synonym: cardiac fibrous skeleton, cardiac skeleton, skeleton of heart. (05 Mar 2000) |
| malignant fibrous histiocytoma | <tumour> A deeply situated tumour, especially on the extremities of adults, frequently recurring after surgery and metastasizing to the lungs; shows partial fibroblastic and histiocytic differentiation with a variable storiform pattern, myxoid areas, and giant cells. (05 Mar 2000) |
| central fibrous body | <anatomy, cardiology> The fibrous area where the leaflets of the aortic, mitral, and tricuspid valves meet in the heart. (05 Mar 2000) |
| right fibrous trigone | Part of the fibrous skeleton of the heart located between the aortic fibrous ring and rings surrounding the right and left atrioventricular ostia. Synonym: trigonum fibrosum dextrum. (05 Mar 2000) |
| metaphysial fibrous cortical defect | A small (less than 2 to 3 cm in diameter) fibrous cortical d. (05 Mar 2000) |
| chronic fibrous thyroiditis | A rare fibrous induration of the thyroid gland, with adhesion to adjacent structures, which may cause tracheal compression. Synonym: chronic fibrous thyroiditis, ligneous struma, ligneous thyroiditis, Riedel's disease, Riedel's struma. (05 Mar 2000) |
| monostotic fibrous dysplasia | Fibrous dysplasia of a single bone. Synonym: localised osteitis fibrosa, osteitis fibrosa circumscripta. (05 Mar 2000) |
