19.3.7. Core and Shell Body Temperature

When referring to an animal's body Temperature, reference is usually made to the temperature of the deep body regions, i.e., Tissues lying more than 2.5 cm beneath the Skin surface. Such a "core" temperature is typically measured in the rectum. In other PARTS OF THE body, the temperature can vary considerably depending on their Location and the ambient temperature (Fig. 19.8).

Fig. 19.8. Human skin temperature at various distances from point X, located near the upper margin of the pelvic region. Throughout the study period, the air temperature was 19 °C. The low skin temperature in the patellar region presumably reflects a poorer Blood supply to this area.
