What is the role of a receptor in the stimulus response model?

• To adjust output or secretions

• To process and relay information

• To detect and register a change

• To remove the initial stimulus

What does a modulator do in the stimulus response model?

• Detects and registers changes

• Adjusts output or secretions

• Processes the change and relays information

• Removes the initial stimulus

What is the function of an effector in the stimulus response model?

• To detect environmental changes

• To process and relay information

• To cause an effect by adjusting output or secretions

• To register a change

What is the outcome of the adjustments made in response to a stimulus called?

• Stimulus

• Receptor

• Modulator

• Response

What role does the effector play in the stimulus response process shown?

• It sends signals to the brain

• It receives the initial stimulus

• It responds to signals from the motor neuron

• It relays signals within the spinal cord

What is the primary function of the nervous system as described in the image?

• To pump blood throughout the body

• To use nerves to receive and send messages quickly

• To filter blood through the kidneys

• To absorb nutrients from food

Which receptors are responsible for detecting stimuli like pressure, touch, and sound?

• Pain receptors

• Thermoreceptors

• Mechanoreceptors

• Photoreceptors

Negative feedback is the process where to maintain homeostasis the body responds by counteracting the stimulus. For example if body temperature increases then the body will do something to cool the body down bringing the body temperature back to normal. If body temperature decreases, what would be an appropriate negative feedback?

• Body starting to sweat.

• Muscles being used to turn on the air conditioning to cool down further.

• Muscles being used to remove clothing to cool down further.

• The body shivering to produce metabolic heat to warm the body up.
