Following statements are regarding to the heat production by the activation of sympathetic nervous system.

A. Activation is stimulation of β receptors in brown fat, which increases metabolic rate and heat production.

B. Activation is stimulation of α2 receptors in brown fat, which increases metabolic rate and heat production.

C. Stimulation of α1 receptors in vascular smooth muscle of skin blood vessels, producing vasoconstriction. Vasoconstriction reduces blood flow to the surface of the skin.

D. Stimulation of α1 receptors in vascular smooth muscle of skin blood vessels, producing vasodilation. Vasodilation reduces blood flow to the surface of the skin.

The temperature of the body is regulated almost entirely by nervous feedback mechanisms, and almost all these mechanisms operate through temperature regulating centers located in the hypothalamus. Following statements are as follows:

A. The anterior hypothalamic-preoptic area contains large numbers of heat-sensitive neurons, as well as about one third as many cold-sensitive neurons. These neurons are believed to function as temperature sensors for controlling body temperature.

B. The heat-sensitive neurons increase their firing rate 2- to 10-fold in response to a 10°C increase in body temperature. 

C. The cold-sensitive neurons, by contrast, increase their firing rate when the body temperature increases.

D. Anterior hypothalamus integrates the central and peripheral temperature sensory signals.
