Functions of the Nervous System. Sensory input – gathering information. To monitor changes occurring inside and outside the body. Changes = stimuli. Integration. To process and interpret sensory input and decide if action is needed. NERVOUS SYSTEM. NERVOUS SYSTEMS RECEIVE SENSORY INPUT, INTEPRET IT, AND SENT OUT APPROPRIATE COMMANDS. NERVOUS SYSTEMS.
