The diagram shows the effects of changing the set point of the hypothalamic temperature controller. Which set of changes occurs at point W compared with point V?
When the set point of the hypothalamic temperature-control centre is suddenly changed from the normal level to higher than normal it produces chilly sensations and shivering. To counteract the cold as perceived by hypothalamus, heat generating and heat preserving mechanism gets activated. One such mechanism of heat preservation is vasoconstriction. It is characteristics of febrile conditions.
