What does the nervous system do? Primitive organisms respond to threats by reflex withdrawal and explore their environment through goal-directed activities. They sense and respond to their internal environment in order to maintain homeostasis. From these origins emerge more sophisticated forms of discriminative sensation and the acquisition of special senses; precision in the efficiency of movement and coordination between separate elements of motor skills; and cognitive behaviours that anticipate, conceptualize, and enrich physical and social interactions with the environment.
