Negative Feedback
A negative feedback system has three basic components (Figure 1.10a).
A sensor, also referred to a receptor, is a component of a feedback system that monitors a physiological value.
This value is reported to the control center. The control center is the component in a feedback system that compares the value to the normal range. If the value deviates too much from the set point, then the control center activates an effector.
An effector is the component in a feedback system that causes a change to reverse the situation and return the value to the normal range.
