Homeostasis Maintaining internal balance whoaa! Mechanisms of homeostasis moderate changes in the internal environment Any homeostatic control system has 3 functional components: a receptor, a control center and an effector Regulators & Conformers regulators try to maintain the parameter at a constant level even with varying environmental variations. (ex: ectothermic animals? almost all other organisms?exhibit wide body temperature variation. (ex: endothermic mammals and birds maintain a constant body temperature) conformers allow the environment to determine the parameter. Negative feedback A change in an internal variable will stimulate a response that counteracts the initial fluctuation until the system goes back to its normal state Negative feedback Negative feedback
