Negative feedback is a regulatory mechanism in which an initial change in a system is detected and then reversed, returning the system to its ideal state or set point. The prevention of change and the shutdown of an overactive organ are examples of negative feedback because they are aimed at maintaining or restoring homeostasis, which is the state of steady internal conditions necessary for optimal functioning. Positive feedback, on the other hand, amplifies and reinforces a change, leading to instability rather than stability. Effector control refers to the action of an effector, such as a muscle or gland, that produces a response to a stimulus. However, effector control is not a mechanism of feedback regulation in and of itself.
