Negative Feedback Loop• Stimulus- produces a change to a variable (the factor

being regulated).• Receptor- detects the change. The receptor monitors

the environment and responds to change (stimuli).• Input- information travels along the (afferent)

pathway to the control center. The control center determines the appropriate response and course of action.

• Output- information sent from the control center travels down the (efferent) pathway to the effector.

• Response- a response from the effector balances out the original stimulus to maintain homeostasis.
