In homeostasis, what is it that produces the response that moves the physiological variable back towards the middle of its healthy range?

effector

Explanation:If the value is not at the set point or is outside the normal range, the control center sends a signal to the effector. The effector is an organ, gland, muscle, or other structure that acts on the signal from the control center to move the variable back toward the set point.
