| 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. (05 Mar 2000) |
| 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.

| administration, rectal | The insertion of drugs into the rectum, usually for confused or incompetent patients, like children, infants, and the very old or comatose. (12 Dec 1998) |
| cancer, rectal | A malignant tumour arising from the inner wall of the end (rectum) of the large intestine. The third leading cause of cancer in males, fourth in females in the U.S. Risk factors for cancer of the colon and rectum (colorectal cancer) include heredity, colon polyps, and long standing ulcerative colitis. most colorectal cancers develop from polyps. Removal of colon polyps can prevent colorectal cancer. Colon polyps and early cancer can have no symptoms. Therefore, regular screening is important. Diagnosis can be made by barium enema or by colonoscopy with biopsy confirmation of cancer tissue. Surgery is the most common treatment for colorectal cancer. (12 Dec 1998) |
| rectal | <anatomy> Pertaining to the rectum, the distal portion of the large intestine. (18 Nov 1997) |
| rectal ampulla | A dilated portion of the rectum just above the anal canal. Synonym: ampulla recti, ampulla of rectum. (05 Mar 2000) |
| rectal anaesthesia | General anaesthesia produced by instillation into the rectum of a solution containing a central nervous system depressant. (05 Mar 2000) |
| rectal cancer | A malignant tumour arising from the inner wall of the large intestine. The third leading cause of cancer in males, fourth in females in the u.s. Risk factors include heredity (family history), colon polyps, and long-standing ulcerative colitis. most colorectal cancers develop from polyps. Colon polyp removal can prevent colorectal cancer. Colon polyps and early cancer can have no symptoms so regular screening is important. Diagnosis of colorectal cancer can be made by barium enema or by colonoscopy with biopsy confirmation of cancer.

| rectal columns | A number of vertical ridges in the mucous membrane of the upper half of the anal canal formed as the caliber of the canal is sharply reduced from that of the rectal ampulla. Synonym: columnae anales, Morgagni's columns, rectal columns. (05 Mar 2000) |
| rectal fistula | Abnormal passage communicating with the rectum. (12 Dec 1998) |
