Effector

Definition

An effector is a component in a feedback system that receives signals from the control center and produces a response to maintain homeostasis. It can be a muscle, gland, or organ that acts to restore equilibrium.

5 Must Know Facts For Your Next Test

1. Effectors are part of the feedback loop in maintaining homeostasis.
2. They receive instructions from the control center to counteract changes detected by sensors.
3. Common effectors include muscles (which can contract) and glands (which can secrete hormones).
4. The action of an effector is crucial for processes such as temperature regulation and glucose levels.
5. Effectors help bring physiological parameters back to their set points after deviation.
