Stimulus-Response Model

What is the correct order of the stimulus-response model?

• A) Stimulus, Effector, Receptor, Control centre, Response

• B) Stimulus, Receptor, Control centre, Effector, Response

• C) Receptor, Stimulus, Control centre, Effector, Response

• D) Stimulus, Control centre, Receptor, Effector, Response

Fill in the blank: In the stimulus-response model, a stimulus is a ______ (either increase or decrease) in the level of an internal variable.

• either increase or decrease

• constant change

• random fluctuation

• sudden spike

Fill in the blank: In the stimulus-response model, a receptor is a structure that detects the change and sends information to the ______.

• the effector.

• the brain.

• the spinal cord.

• the muscle.

What is the role of the Control (Coordination) Centre in the stimulus-response model?

• It sends signals to the effector about the correction needed.

• It adjusts its output to make the required correction.

• It takes the corrective action.

What does the Effector do in the stimulus-response model?

• Evaluates the changes against the set point for that variable.

• Sends signals to the effector about the correction needed.

• Adjusts its output to make the required correction.

Fill in the blank: In the stimulus-response model, the Response is the _________.

• corrective action taken.

• stimulus detected.

• initial trigger.

• external factor.
