Nervous System Quiz

What is the ultimate control center of the body that oversees all communication among the organ systems?

• The heart

• The liver

• The brain

• The lungs

What is the role of sensory input in the body's control system?

• It activates effector organs to cause a response.

• It processes the input stimuli and decides what should be done.

• It receives stimuli via millions of sensory receptors throughout the body.

• It oversees all communication among the organ systems.
