#7. System Physiology – Animal
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.
