GENERAL HISTOLOGY

Detailed explanation-1: -The average normal body temperature is generally accepted as 98.6°F (37°C). Some studies have shown that the “normal” body temperature can have a wide range, from 97°F (36.1°C) to 99°F (37.2°C). A temperature over 100.4°F (38°C) most often means you have a fever caused by an infection or illness.

Detailed explanation-2: -An adult probably has a fever when the temperature is above 99°F to 99.5°F (37.2°C to 37.5°C), depending on the time of day.

Detailed explanation-3: -A normal rectal body temperature ranges from 97.5°F (36.4°C) to 99.6°F (37.6°C), and for most people it is 98.6°F (37°C).
