| third peroneal muscle | <anatomy, muscle> Origin, in common with musculus extensor digitorum longus; insertion, dorsum of base of fifth metatarsal bone; nerve supply, deep branch of peroneal; action, assists in dorsiflexion and eversion of foot. Synonym: musculus fibularis tertius, musculus peroneus tertius, third peroneal muscle. (05 Mar 2000) |

| third sound | Occurs in early diastole and corresponds with the end of the first phase of rapid ventricular filling; normal in children and younger people but abnormal in others. Synonym: third sound. (05 Mar 2000) |
| third stage of labour | The part of labour from the birth of the baby until the placenta (afterbirth) and foetal membranes are delivered. The third stage of labour is also called the placental stage. (12 Dec 1998) |
| third temporal convolution | A sagittal convolution on the inferolateral border of the temporal lobe of the cerebrum, separated from the middle temporal gyrus by the inferior temporal sulcus. On the inferior surface of the temporal lobe it is separated from the medial occipitotemporal gyrus by the occipitotemporal sulcus. It includes the lateral occipitotemporal gyrus. Synonym: gyrus temporalis inferior, inferior temporal convolution, third temporal convolution. (05 Mar 2000) |
| third tonsil | A collection of more or less closely aggregated lymphoid nodules on the posterior wall and roof of the nasopharynx, the hypertrophy of which constitutes the morbid condition called adenoids. Synonym: tonsilla pharyngealis, tonsilla adenoidea, Luschka's gland, Luschka's tonsil, third tonsil. (05 Mar 2000) |
| third trochanter | An occasional process at the proximal end of the lateral lip of the linea aspera of the femur, about on a level with the lesser trochanter, giving insertion to the greater part of the gluteus maximus muscle. See: gluteal tuberosity. (05 Mar 2000) |
| third ventricle | A narrow, vertically oriented, irregularly quadrilateral cavity in the midplane, extending from the lamina terminalis to the rostral opening of the mesencephalic aqueduct. This ventricle communicates at its rostrodorsal corner with each of the two lateral ventricles through the left and right interventricular foramen of Monro. Its narrow roof is formed by the tela choroidea which is attached on either side to the tenia thalami; its lateral wall by the medial surface of the thalamus and, below the hypothalamic sulcus, by the hypothalamus which also forms its floor. In lateral profile, the third ventricle exhibits a number of recesses: in its floor, from before backward, 1) the preoptic recess in the acute angle between the base of the lamina terminalis and the dorsum of the optic chiasm, 2) the infundibular recess extending ventrally into the infundibulum but (in humans) not into the hypophysial stalk, and 3) the mamillary or inframamillary recess caused by the protrusion of the mamillary bodies into the ventricle. From its dorsocaudal corner, the pineal recess extends caudally into the pineal stalk. Synonym: ventriculus tertius, diacele, ventricle of diencephalon. (05 Mar 2000) |
| third ventriculostomy | An operation to establish an opening from the third ventricle to the prechiasmal and interpeduncular cisterns (Stookey-Scarff operation) or from the third ventricle to the interpeduncular cistern (Dandy operation). (05 Mar 2000) |
| third-order kinetics | <pharmacology> A term describing the reaction rate of a chemical reaction in which the rate is proportional to the product of the concentrations (in moles) of three of the reactants, the product of the molar concentration of one reactant and the square of the molar concentration of another reactant, or the cube of the molar concentration of one of the reactants. Such a reaction might have an equation like rate = k[A][B][C] or rate = [A][B]2 or rate = [A]3, where k is the reaction rate constant, [A] is the concentration of reactant A, [B] is the concentration of reactant B, and [C] is the concentration of reactant C.

| thirst fever | An elevation of temperature in infants after reduction of fluid intake, diarrhoea, or vomiting; probably caused by reduced available body water, with reduced heat loss by evaporation; an analogous condition in adults is seen when exertion is continued in the face of dehydration. Synonym: dehydration fever, exsiccation fever, inanition fever. (05 Mar 2000) |
| Thiry | Ludwig, Austrian physiologist, 1817-1897. See: Thiry's fistula, Thiry-Vella fistula. (05 Mar 2000) |
| Thiry's fistula | An artificial fistula for collecting the intestinal secretions of a dog or other animal for experimental purposes; a loop of intestine is isolated, its vascular and nervous connections are preserved, and the continuity of the intestinal tract is restored by anastomosis; one end of the isolated segment is closed, the other attached to the skin of the abdomen. (05 Mar 2000) |
| Thiry-Vella fistula | Experimental isolation of a segment of intestine in a dog or other animal; the mesenteric attachment is preserved, the divided intestine at each end of the segment is joined by anastomosis, and the ends of the segment are stitched to openings in the abdominal wall. Synonym: Vella's fistula. (05 Mar 2000) |
| this | Origin: OE. This, thes, AS. Oes, masc, oeos, fem, ois, neut.; akin to OS. These, D. Deze, G. Dieser, OHG. Diser, deser, Icel. Oessi; originally from the definite article + a particle -se, -si; cf. Goth. Sai behold. See The, That, and cf. These, Those. 1. As a demonstrative pronoun, this denotes something that is present or near in place or time, or something just mentioned, or that is just about to be mentioned. "When they heard this, they were pricked in their heart." (Acts II. 37) "But know this, that if the good man of the house had known in what watch the thief would come, he would have watched." (Matt. Xxiv. 43) 2. As an adjective, this has the same demonstrative force as the pronoun, but is followed by a noun; as, this book; this way to town. This may be used as opposed or correlative to that, and sometimes as opposed to other or to a second this. See the Note under That. "This way and that wavering sails they bend." (Pope) "A body of this or that denomination is produced." (Boyle) "Their judgment in this we may not, and in that we need not, follow." (Hooker) "Consider the arguments which the author had to write this, or to design the other, before you arraign him." (Dryden) "Thy crimes . . . Soon by this or this will end." (Addison) This, like a, every, that, etc, may refer to a number, as of years, persons, etc, taken collectively or as a whole. "This twenty years have I been with thee." (Gen. Xxxi. 38) "I have not wept this years; but now My mother comes afresh into my eyes." (Dryden) Source: Websters Dictionary (01 Mar 1998) |

| thimerosal |
A preservative which contains nearly 50% ethyl mercury by weight. The FDA estimates that throughout the 1990s it was used in more than thirty licensed vaccines and biologics marketed in the US. During this time the vaccine schedule for infants included as much as 187 mcg of mercury in the first six months of life--far exceeding levels accepted as safe. Many symptoms of ASD closely resemble those of mercury poisoning. It is no longer used in most vaccines.

| thixotropy |
tendency of grease or other material to soften or flow when subjected to shearing action. Grease will usually return to its normal consistency when the action stops. The phenomenon is the opposite of that which occurs with rheopectic grease. Thixotropy is also an important characteristic of drilling fluids, which must thicken when not in motion so that the cuttings in the fluid will remain in suspension.
