Question

Quizplus · Accepted Answer

An effector is a cell or organ that responds to commands of the control center in negative feedback, producing a response that opposes the initial stimulus. A receptor detects changes in the internal or external environment and communicates this information to the control center, which then sends out commands to effectors. The hypothalamus is a region of the brain that serves as a control center for many homeostatic processes, including temperature regulation. Thermoregulators are organisms or devices that maintain a constant temperature, but this term does not apply to a cell or organ in negative feedback. Stimulus refers to any change in the internal or external environment that activates a receptor.
