The hypothalamus functions as the control center in this homeostatic control system. In a warm environment, thermoreceptors on the skin detect heat and activate nerve cells that send the message to the hypothalamus. The hypothalamus sends nerve impulses to the sweat glands (effectors), prompting them to increase their activity. Once sweat evaporates, the body cools, and signals from the brain to the sweat glands cease.
