The thermoregulatory mechanism consists of:

##'''Sensory Component''': neurones that possess nerve endings with thermoreceptors continuously monitor body temperature and transmit it to the integrating centre. These neurons may be within the skin or internal organs.

##'''Integrating Centre:''' the [[Endocrine System - Hypothalamus - Anatomy & Physiology|Hypothalamus]] is the control centre in the brain which compares the temperature information with an ''Internal Reference'' or ''Set point''.

##'''Motor Component''': neurons which send signals to alter the internal temperature - altering heat production or heat loss.
