Document Summary
The central nervous system is the brain and spinal cord. The peripheral nervous system connects the brain and spinal cord to the rest of the body. The somatic nervous system: axons that send messages from the sense organs to the central nervous system and from the central nervous system to the muscles. The autonomic nervous system controls the heart, intestines and other organs, has some cells in the brain or spinal cord and some clusters along the sides of the spinal cord, controls involuntary muscles. Terms for anatomical directions in the nervous system. The spinal cord communicates with all the sense organs and muscles except the ones of the head. The spinal cord is made up of segments and each segment has a sensory nerve and a motor nerve. Dorsal roots carry sensory information to the spinal cord. Ventral roots carry motor information to the muscles.
