Which of the following events occurs during Phase B to raise body
temperature to hypothalamus set point?
A. Shivering
B. Sweating
C. Decrease in thermogenesis
D. Cutaneous vasodilation
Answer. A
Solution. Shivering is an event that occurs during Phase B to raise body temperature to the
hypothalamus set point. Shivering is a physiological response that increases heat production by
generating muscle contractions, which in turn leads to an increase in body temperature. The
hypothalamus set point is the temperature at which the hypothalamus, the part of the brain
responsible for regulating body temperature, is set to maintain the body temperature. When the
body temperature drops below the set point, the hypothalamus triggers mechanisms such as
shivering to raise the body temperature back to the set point.
