Web(a) A negative feedback system has five basic parts. (b) Body temperature is regulated by negative feedback. In order to set the system in motion, a stimulus must drive a physiological parameter beyond its normal range (that is, beyond homeostasis). This stimulus is “heard” by a specific sensor.
