| temperature sense | The sensation of cold, heat, coolness, and warmth. (12 Dec 1998) |

| temperature sensitive mutation | <genetics, molecular biology> A type of conditional mutation in organism, somatic cell or virus that makes it possible to study genes whose total inactivation would be lethal. Such ts mutations can also make possible studies of the effect of reversible switching by temperature changes) in expression of the mutated gene. The usual mechanism of temperature sensitivity is that the mutated gene codes for a protein with a temperature dependent conformational instability, so that it possesses normal activity at one temperature (the permissive temperature), but is inactive at a second (nonpermissive) temperature.

| temperature spot | One of a number of definitely arranged spot's on the skin sensitive to heat and cold, but not to ordinary pressure or pain stimuli. (05 Mar 2000) |
| temperature, plasma | <radiobiology> A measure of the random (thermal) kinetic energy of the ions or electrons in the plasma. The temperature of each component of a plasma depends on the mean kinetic energy of that component. An example of this is the fluorescent light bulb, which is an example of a weakly-ionised plasma where the electrons are at temperatures of tens of thousands of degrees, whereas the ions and neutrals are much cooler (so that you can touch the bulb without being burned). See: atomic temperature, electron temperature, ion temperature. (09 Oct 1997) |
| temperature-compensated vaporiser | A vaporiser of liquid anaesthetics with graduated settings calibrated to deliver a known constant concentration of a specific anaesthetic despite changes in inflow volume and despite cooling brought about by vaporization. (05 Mar 2000) |
| temperature-sensitive mutant | A viral mutant that is able to replicate at one portion of a temperature range but not at another, the parent (wild type) strain being able to replicate over the whole temperature range. Compare: cold-sensitive mutant, quick-stop mutant. (05 Mar 2000) |
| tempering | <chemistry> The process of giving the requisite degree of hardness or softness to a substance, as iron and steel; especially, the process of giving to steel the degree of hardness required for various purposes, consisting usually in first plunging the article, when heated to redness, in cold water or other liquid, to give an excess of hardness, and then reheating it gradually until the hardness is reduced or drawn down to the degree required, as indicated by the colour produced on a polished portion, or by the burning of oil. Tempering colour, the shade of colour that indicates the degree of temper in tempering steel, as pale straw yellow for lancets, razors, and tools for metal; dark straw yellow for penknives, screw taps, etc.; brown yellow for axes, chisels, and plane irons; yellow tinged with purple for table knives and shears; purple for swords and watch springs; blue for springs and saws; and very pale blue tinged with green, too soft for steel instruments.

| tempero-mandibular joint | The TMJ hinges the lower jaw (mandible) to the skull. (12 Dec 1998) |
| tempero-mandibular joint syndrome | <syndrome> Disorder of the temporo-mandibular joint(s) causing pain usually in front of the ear(s). Pain in the tmj can be due to trauma (such as a blow to the face), inflammatory or degenerative arthritis, or by the mandible being pushed back towards the ears whenever the patient chews or swallows. Sometimes, muscles around the tmj used for chewing can go into spasm, causing head and neck pain and difficulty opening the mouth normally. (12 Dec 1998) |
| template | 1. A structure that in some direct physical process can cause the patterning of a second structure, usually complementary to it in some sense. 2. <molecular biology> Almost exclusively used to refer to a nucleotide sequence that directs the synthesis of a sequence complementary to it by the rules of Watson Crick base pairing. (16 Dec 1997) |
| template RNA | mRNA |
| templates | Macromolecular moulds for the synthesis of complementary macromolecules, as in DNA replication, transcription of DNA to RNA, and translation of RNA into polypeptides. (12 Dec 1998) |
| temple | 1. <anatomy> The space, on either side of the head, back of the eye and forehead, above the zygomatic arch and in front of the ear. 2. One of the side bars of a pair of spectacles, jointed to the bows, and passing one on either side of the head to hold the spectacles in place. Origin: OF. Temple, F. Tempe, from L. Tempora, tempus; perhaps originally, the right place, the fatal spot, supposed to be the same word as tempus, temporis, the fitting or appointed time. See Temporal of time, and cf. Tempo, Tense.

| templed | Supplied with a temple or temples, or with churches; inclosed in a temple. "I love thy rocks and rills, Thy woods and templed hills." (S. F. Smith) Source: Websters Dictionary (01 Mar 1998) |
| templet | 1. A gauge, pattern, or mold, commonly a thin plate or board, used as a guide to the form of the work to be executed; as, a mason's or a wheelwright's templet. 2. A short piece of timber, iron, or stone, placed in a wall under a girder or other beam, to distribute the weight or pressure. Origin: LL. Templatus vaulted, from L. Templum a small timber. Spelt also template. Source: Websters Dictionary (01 Mar 1998) |
