Peripheral nervous system: nerves outside the brain and spinal cord, connects it to rest of the body somatic nervous system: consists of axons conveying messages from the sense organs to the cns and from cns to the muscles. Autonomic nervous system: controls the heart, intestines, and other organs sympathetic: expends energy. Ex; in a four-legged animal, the top of brain is doral (on same side as the ventral: toward the stomach animal"s back) and bottom of the brain is ventral (on stomach side) Part of the cns within the spinal column, communicates with all the sense organs and muscles except those of the head, segmented with sensory and a motor nerve on each. Each segments sends sensory info. to the brain and receives motor commands from the brain.
