An effector is a response for a particular stimulus. Effector can either oppose a particular stimulus or enhance it. This process can be useful for maintaining homeostasis. Homeostasis involves the maintainence of internal body temperature by the organism for sustainence of life. For example, while regulating body temperature, the heat or cold stimuli are detected by receptors in skin, which transfer information to brain and then to effectors, the effectors generates response in the form of bodily action. Effectors in the brain will activate those in blood vessels and sweat glands in response to heat and cold stimuli in regulating body heat or temperature.
