Why is salivation after seeing tasty food a good example of control and coordination?
Answer and explanation
Correct answer: Because a sensory signal goes to the brain and causes a gland response
Seeing appetising food provides a visual stimulus. Receptors in the eye send nerve impulses to the brain, where the information is processed. The brain then sends signals that stimulate the salivary glands to secrete saliva, preparing the mouth for digestion. This pathway shows coordination among a sense organ, the nervous system, and an effector gland; the other options are incorrect.
