Which of the following best describes the nervous system function of integration? The nervous system processes and interprets sensory input and decides what should be done at each moment. The nervous system causes a response by activating effector organs, such as the muscles and glands. The nervous system generates neurons in order to replace or repair damaged neurons; this permits optimal communication between the CNS and the body's effector organs. The nervous system uses its millions of sensory receptors to monitor changes occurring both inside and outside the body.
