Page 4: Research news on Body Temperature Regulation

Body temperature regulation, or thermoregulation, is the biological process by which organisms maintain internal body temperature within a physiologically optimal range despite external or internal thermal perturbations. In homeothermic animals, this involves coordinated neural, endocrine, and autonomic mechanisms centered primarily in the hypothalamus, which integrates thermal sensory input from peripheral and core thermoreceptors. Effectors include changes in blood flow (vasodilation and vasoconstriction), sweating or panting, shivering thermogenesis, non-shivering thermogenesis (e.g., brown adipose tissue activity), and behavioral responses such as seeking shade or warmth. Thermoregulation is critical for enzymatic function, metabolic homeostasis, and overall organismal survival.
