At the normal set point, the body temperature, as measured with an oral thermometer, will be approximately 37Â°C (98.6Â°F). If body temperature rises above 37.2Â°C, activity in the control center targets two effectors: (1) muscle tissue in the walls of blood vessels supplying the skin and (2) sweat glands.
Normal body temperature varies by person, age, activity, and time of day. The average normal body temperature is generally accepted as 98.6Â°F (37Â°C). Some studies have shown that the normal body temperature can have a wide range, from 97Â°F (36.1Â°C) to 99Â°F (37.2Â°C).
