Document Summary

The control center allowing the body to react to the environment. Comprised of: brain, spinal cord, nerves and ganglia. There are three different ways it is classified: Functional (central and peripheral) (sensory and motor) (somatic and autonomic) Central nervous system (cns) the control center. Peripheral nervous system (pns) all the nerve processes connecting to the cns. Takes into account the activities that are directed by the nervous system. Somatic nervous system (sns) conscious, voluntary information from the cns to the skeletal muscles. Autonomic nervous system (ans) carries involuntary information (sensory and motor) to smooth muscle, cardiac muscle and glands of the body. Involves 2 nerve cells to reach the target. Takes into account the impulses (sensory or motor) carried by the nerves and the direction they travel. Afferent system (sensory) conducts information from the periphery to the central nervous system. Efferent system (motor) nerves traveling from the central nervous system to a peripheral structure produces a motor activity.
