(e.g. muscles and glands) negative feedback - When receptors measure deviations from the set point, effectors are activated and conditions are returned toward the set point and effectors gradually shut off. This movement toward homeostasis and balance is called ......... positive feedback - Homeostatic mechanisms that function when changes byeffectors move the body away from normal conditions, causing more changes, is called......
