AP PSYCHOLOGY

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: -The receptor senses the change in the environment, then sends a signal to the control center (in most cases, the brain) which in turn generates a response that is signaled to an effector.

Detailed explanation-3: -Receptors (sensors) detect changes in the variable. Control centers (integrators) compare the variable in relation to a set point and signal the effectors to generate a response.

Detailed explanation-4: -Receptor-the site within the body that detects or receives the stimulus, senses the change from normal, and sends signals to the control center.

Detailed explanation-5: -In terms of temperature regulation, the control center is located in the hypothalamus, a small region in the brain, and the effectors would include skeletal muscle (shivering), sweat glands (sweating) and blood vessels. It is also interesting that the human body can change a set point for a particular variable.
