Document Summary

Central nervous system (cns: brain, spinal cord. Between each pair of spinal vertebral a pair of nerves leave the spinal column. After leaving the spinal column the nerves reconnect and form new branchings. Types of nerves the peripheral nervous systems have two types of nerve really two directions by which information flows. Afferent nerves (also called sensory nerves: carry information to the central nervous system, bring information back to brain, sensory tells (cid:449)hat(cid:859)s goi(cid:374)g o(cid:374) arou(cid:374)d your (cid:271)ody. Efferent nerves (also called motor nerves: carry information from the central nervous system, away from the brain, voluntary movements. It is the motor nerves that carry commands from the brain to the muscles, causing voluntary movements. Motor nerves leave the brain and spinal column in pairs at distinct levels. The area of muscle controlled by a specific nerve pair is called a myotome. Myotomes differ slightly between people, but they can be mapped (look at slide)
