Summary Introduction

To review:

The function of the control center in a negative feedback control system.

Introduction:

Homeostasis is the process that occurs in the body to maintain a constant, stable internal condition even when the external environment changes continuously. The homeostasis in the body is constantly being regulated by various positive and negative feedback mechanisms. Generally, the negative feedback mechanisms control the homeostatic mechanisms. In these systems, the net effect of the response is either reduced or shut off.

The automatic detection of any deviation of system activity from its normal state and the counteraction on the variables of the system activity to return back to its normal state occurs. The negative feedback loop involves three different components, namely, the receptors, control center, and effectors.
