Members of the family include: aequorin, _ actinin, calbindin, calcineurin, calcyphosin, calmodulin, calpain, calcyclin, iacylglycerol kinase, fimbrin, myosin regulatory light chains, oncomodulin, osteonectin, spectrin, troponin C.

| trench hand | An obsolete term for frostbite of the hand. (05 Mar 2000) |
| trident hand | A hand in which the fingers are of nearly equal length and deflected at the first interphalangeal joint, so as to give a forklike shape; seen in achondroplasia. (05 Mar 2000) |
| two-hand | Employing two hangs; as, the two-hand alphabet. See Dactylology. Source: Websters Dictionary (01 Mar 1998) |

| 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.

| 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.

| 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) |
