WebK.C. Mendoza, J.D. Griffin, in Encyclopedia of Behavioral Neuroscience, 2010. Thermoregulation is a dynamic, homeostatic interaction between an organism’s internal processes and its external environment, to maintain a stable, physiological temperature. Among mammals, thermoregulatory heat loss behavior includes vasodilation, panting, … WebHow metabolic rate varies with body size and activity level. Key points: Metabolism is inefficient and produces heat. Endotherms use metabolic heat to keep a stable body temperature, while ectotherms do not.

A previous study showed that the size of the nasal cavity in ectotherms and endotherms correlates with body size. “But its physiological role has been controversial,” said Seishiro Tada, a graduate student at the University of …

WebThermoregulation is coordinated by the nervous system (Figure 16.2). The processes of temperature control are centered in the hypothalamus of the advanced animal brain. The hypothalamus maintains the set point for body temperature through reflexes that cause vasodilation or vasoconstriction and shivering or sweating. WebBody size and shape fundamentally determine organismal energy requirements by modulating heat and mass exchange with the environment and the costs of locomotion, thermoregulation, and maintenance.
