Body Temperature Regulation
The processes of heating and cooling that an organism uses to control its temperature.
Temperature
The property of objects that determines the direction of heat flow when they are placed in direct thermal contact. The temperature is the energy of microscopic motions (vibrational and translational) of the particles of atoms.
Skin Temperature
The TEMPERATURE at the outer surface of the body.
Sweating
Hypothermia
Lower than normal body temperature, especially in warm-blooded animals.
Cold Temperature
An absence of warmth or heat or a temperature notably below an accustomed norm.
Pyrogens
Substances capable of increasing BODY TEMPERATURE and cause FEVER and may be used for FEVER THERAPY. They may be of microbial origin, often POLYSACCHARIDES, and may contaminate distilled water.
Fever
An abnormal elevation of body temperature, usually as a result of a pathologic process.
Hypothalamus
Hot Temperature
Presence of warmth or heat or a temperature notably higher than an accustomed norm.
Hypothalamus, Anterior
The front portion of the HYPOTHALAMUS separated into the preoptic region and the supraoptic region. The preoptic region is made up of the periventricular GRAY MATTER of the rostral portion of the THIRD VENTRICLE and contains the preoptic ventricular nucleus and the medial preoptic nucleus. The supraoptic region contains the PARAVENTRICULAR HYPOTHALAMIC NUCLEUS, the SUPRAOPTIC NUCLEUS, the ANTERIOR HYPOTHALAMIC NUCLEUS, and the SUPRACHIASMATIC NUCLEUS.
