| flexor digiti minimi brevis muscle of hand | Origin, hamulus of hamate bone; insertion, medial side of proximal phalanx of little finger; action, flexes proximal phalanx of little finger; nerve supply, ulnar. Synonym: musculus flexor digiti minimi brevis manus, short flexor muscle of little finger. (05 Mar 2000) |

| free-hand knife | A manually operated knife or blade usually used to take split-thickness skin grafts; e.g., Blair-Brown knife, Humby knife, Theirsh knife. (05 Mar 2000) |
| lumbrical muscle of hand | Four intrinsic muscles of the hand; origin, the two lateral: from the radial side of the tendons of the flexor digitorum profundus going to the index and middle fingers; the two medial: from the adjacent sides of the second and third, and third and fourth tendons; insertion, radial side of extensor tendon on dorsum of each of the four fingers; action, flexes metacarpophalangeal joint and extends the proximal and distal interphalangeal joint; nerve supply, the two radial muscles by the median, the two ulnar muscles by the ulnar. Synonym: musculus lumbricalis manus. (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) |
| monostotic fibrous dysplasia | Fibrous dysplasia of a single bone. Synonym: localised osteitis fibrosa, osteitis fibrosa circumscripta. (05 Mar 2000) |
| polyostotic fibrous dysplasia | The occurrence of lesions of fibrous dysplasia in multiple bones, commonly on one side of the body; may occur with areas of pigmentation and endocrine dysfunction (McCune-Albright syndrome). Synonym: multifocal osteitis fibrosa, osteitis fibrosa disseminata. (05 Mar 2000) |
| histiocytoma, fibrous | A tumour composed, wholly or in part, of cells with the morphologic characteristics of histiocytes and with various fibroblastic components. There are many variants and many names. Superficially located histiocytic lesions behave benignly but deep, benign histiocytomas may invade locally into surrounding tissue. Fibrous histiocytomas can occur anywhere in the body. Superficial lesions are always cured by simple excision; a wider margin of tissue should be obtained for deep, benign types. Local recurrence is uncommon. (12 Dec 1998) |
| solitary fibrous tumour | A benign tumour of fibrous tissue which usually arises in the pleural space on other sites. Synonym: benign mesothelioma. (05 Mar 2000) |
| neoplasms, fibrous tissue | Neoplasms composed of fibrous tissue, the ordinary connective tissue of the body, made up largely of yellow or white fibres. The concept does not refer to neoplasms located in fibrous tissue. (12 Dec 1998) |
