Which physiological outcome occurs when a mammal's core body temperature acutely drops and shivering commences?

💡 Explanation

When core temperature drops, shivering—rapid muscle contractions—begins via the hypothalamus activating motor neurons, causing muscles to expend energy, increasing metabolic heat via muscle contraction. Therefore, elevated heat occurs, rather than vasodilation, depressed brown fat oxidative metabolism, or lessened glucose uptake, which generate different adaptive responses.
