Runaway reaction, a chemical reaction releasing more heat than what can be removed and becoming uncontrollable; Thermal runaway, self-increase of the reaction rate of an exothermic process while temperature increases with the heat released and giving rise to an explosion
Simplified control circuit of human thermoregulation. [8]The core temperature of a human is regulated and stabilized primarily by the hypothalamus, a region of the brain linking the endocrine system to the nervous system, [9] and more specifically by the anterior hypothalamic nucleus and the adjacent preoptic area regions of the hypothalamus.
