| gas thermometer | A thermometer filled with dry air or a gas, the expansion or increased pressure of which indicates the degree of heat; used to measure high temperatures. (05 Mar 2000) |

| resistance thermometer | A device measuring temperature by the change of the electrical resistance of a metal wire. Synonym: resistance pyrometer. (05 Mar 2000) |
| clinical thermometer | A small, self-registering thermometer, consisting of a simple scaled glass tube containing mercury, used for taking the temperature of the body. (05 Mar 2000) |
| water thermometer | <physics> A thermometer filled with water instead of mercury, for ascertaining the precise temperature at which water attains its maximum density. This is about 39 deg Fahr, or 4 deg Centigrade; and from that point down to 32 deg Fahr, or 0 deg Centigrade, or the freezing point, it expands. Source: Websters Dictionary (01 Mar 1998) |
| wet and dry bulb thermometer | An instrument for measuring the tension of the aqueous vapor in the atmosphere, being essentially a wet and dry bulb hygrometer. Origin: Gr. Psychros cold: cf. F. Psychrometre. Source: Websters Dictionary (01 Mar 1998) |
| self-registering thermometer | A thermometer in which the maximum or minimum temperature, during the period of observation, is registered by means of a special appliance; in the clinical thermometer only the highest temperature is registered, usually by a steel bar above the column of mercury or by a segment of the mercury separated from the main column by a bubble of air; after the maximum temperature is registered, the bar or segment of mercury remains in place as the column of mercury contracts.

| spirit thermometer | A thermometer filled with alcohol, used to measure extreme degrees of cold. (05 Mar 2000) |
| surface thermometer | A thermometer in the form of a disk or strip that indicates the temperature of the portion of the skin to which it is applied. (05 Mar 2000) |
| differential thermometer | <instrument, physics> An instrument for indicating changes of temperature without indicating the degree of heat by which it is affected; especially, an instrument contrived by Count Rumford which, as modified by Professor Leslie, was afterward called the differential thermometer. Origin: Thermo- + -scope. Source: Websters Dictionary (01 Mar 1998) |
| thermometer | <physics> An instrument for measuring temperature, founded on the principle that changes of temperature in bodies are accompained by proportional changes in their volumes or dimensions. The thermometer usually consists of a glass tube of capillary bore, terminating in a bulb, and containing mercury or alcohol, which expanding or contracting according to the temperature to which it is exposed, indicates the degree of heat or cold by the amount of space occupied, as shown by the position of the top of the liquid column on a graduated scale. See Centigrade, Fahrenheit, and Reaumur. To reduce degrees Fahrenheit to degrees Centigrade, substract 32 deg and multiply by 5/9; to reduce degrees Centigrade to degrees Fahrenheit, multiply by 9/5 and add 32 deg . Air thermometer, Balance thermometer, etc. See Air, Balance, etc. Metallic thermometer, a form of thermometer indicating changes of temperature by the expansion or contraction of rods or strips of metal. Register thermometer, or Self-registering thermometer, a thermometer that registers the maximum and minimum of temperature occurring in the interval of time between two consecutive settings of the instrument. A common form contains a bit of steel wire to be pushed before the column and left at the point of maximum temperature, or a slide of enamel, which is drawn back by the liquid, and left within it at the point of minimum temperature.

| anterior recess of tympanic membrane | A slitlike space on the tympanic wall between the anterior malleolar fold and the tympanic membrane. Synonym: recessus membranae tympani anterior, Troltsch's pockets, Troltsch's recesses. (05 Mar 2000) |
| anterior tympanic artery | <anatomy, artery> Origin, maxillary; distribution, middle ear; anastomoses, tympanic branches of internal carotid and ascending pharyngeal and stylomastoid. Synonym: arteria tympanica anterior, glaserian artery. (05 Mar 2000) |
| anterior wall of tympanic cavity | It contains the carotid canal and the opening of the auditory tube. Synonym: paries caroticus cavi tympani, anterior wall of middle ear, carotid wall of middle ear. (05 Mar 2000) |
| branch of auriculotemporal nerve to tympanic membrane | Sensory branch of the auriculotemporal nerve supplying the external surface of the tympanic membrane. Synonym: ramus membranae tympani nervi auriculotemporalis, nerve of tympanic membrane. (05 Mar 2000) |
| radiate layer of tympanic membrane | The connective tissue layer of the tympanic membrane beneath the stratum cutaneum, the fibres of which radiate from the manubrium of the malleus to the peripheral fibrocartilaginous ring of the membrane; absent from the pars flaccida. Synonym: radiate layer of tympanic membrane. (05 Mar 2000) |
