Question

Quizplus · Accepted Answer

Nonshivering thermogenesis is a mechanism by which the body generates heat without shivering. It is stimulated by epinephrine and thyroid hormone, as they increase metabolic rate and heat production in brown adipose tissue. Shivering thermogenesis, on the other hand, is the involuntary muscle contractions that generate heat.
