Uses new and existing information to send out messages to muscles and glands, allowing for production of behaviours and produces movement. It creates conscious experience (awareness, perceptions, feelings, etc. ) Everything psychological is physiological: neurons, basic function and structure of the neuron. Neurons are the basic unit of communication in the nervous system. There are 10 000 types of neurons in the body, all categorized into 3 major types.
