| lymphopenic thymic dysplasia | An obsolete term for thymic alymphoplasia. (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.

| 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) |
| perivascular fibrous capsule | A layer of connective tissue ensheathing the hepatic artery, portal vein, and bile ducts as these ramify within the liver. Synonym: capsula fibrosa perivascularis, perivascular fibrous capsule. Connective tissue capsule surrounding the outer surface of the liver, but continuous with septae of some animals which divide parenchyme into lobule, and with the perivascular fibrous capsule at the porta hepatis. Synonym: tunica fibrosa hepatis, Glisson's capsule. (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) |
