Which component receives information from the control center and carries out the response?

• A. Receptor
• B. Control center
• C. Effector
• D. Afferent pathway

Answer: (C)

In body control systems, after the control center decides what needs to be done, the instruction is sent to the effector, which carries out the action. The effector is a muscle or gland that responds to restore normal conditions by producing a change in the body. It receives the signal from the control center through the efferent pathway and then executes the response, such as contracting a muscle or secreting a hormone. Receptors are the sensors that detect changes and send information to the control center via the afferent pathway, while the efferent pathway carries commands away from the control center to the effector. So, the component that receives information from the control center and performs the response is the effector.
