Detailed explanation-1: -A sensor or receptor detects changes in the internal or external environment. An example is peripheral chemoreceptors, which detect changes in blood pH. The integrating center or control center receives information from the sensors and initiates the response to maintain homeostasis.

Detailed explanation-2: -Regardless of the system used, if communication flows toward the control center from the receptor, it is termed an afferent pathway. If information flows from the control center to the effector, it is termed an efferent pathway.

Detailed explanation-3: -Receptor-the site within the body that detects or receives the stimulus, senses the change from normal, and sends signals to the control center.
