Core body temperature
Core Body Temperature
Core body temperature (pronunciation: /kɔːr bɒdi ˈtɛmprɪtʃər/) is the temperature of the internal organs, which is considered to be the most accurate representation of body temperature.
Etymology
The term "core body temperature" is derived from the Latin word "corpus" meaning body and the Latin word "temperatura" meaning temperature.
Definition
Core body temperature is the steady temperature of the human body's internal environment. It is maintained within a narrow range around 37°C (98.6°F) for optimal functioning of physiological processes.
Measurement
Core body temperature can be measured using a variety of methods, including rectal, esophageal, and tympanic membrane thermometers. However, these methods are invasive and may not be suitable for routine use. Non-invasive methods such as temporal artery thermometers and infrared thermometers are also used.
Related Terms
