The receptor senses changes in the environment and responds by sending information to the control center along nerve impulses or chemical signals.
receptor
The structure that receives output from the control center in a feedback system is typically the effector. The effector is responsible for carrying out the response dictated by the control center to maintain homeostasis or achieve the desired outcome.

The correct order of a homeostatic control system is: Stimulus - a change occurs in the internal or external environment. Receptor - sensors detect the change in the environment. Control center - processes the information and determines the appropriate response. Effector - carries out the necessary response to restore homeostasis.
In a feedback system, the sequence of events typically involves the initial stimulus activating a sensor, which then sends a signal to the control center. The control center receives the signal, processes the information, and initiates a response by sending signals to effector organs. The effector organs then carry out the necessary actions to counteract the initial stimulus, ultimately restoring balance to the system.
The nervous system starts in the brain, which is the main control center of the body. From the brain, messages are sent through the spinal cord, which acts as a pathway to relay information between the brain and the rest of the body.
The three basic components of every feedback control system are: the sensor (or detector) which measures the system's output, the controller which processes this information and generates a control signal, and the actuator (or final control element) which takes the control signal and adjusts the system's input to achieve the desired output.
