Document Summary

Kinesiology 2241b lecture 7: neuromuscular aspects of movement ii. 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. The peripheral nervous system has two types of nerve two directions by which information flows. Afferent nerves (aka sensory nerves) carry information to the central nervous system. Efferent nerves (aka motor nerves) carry information from the central nervous system. 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, as shown to the right. Sensory nerves enter the brain and spinal column in pairs at distinct levels.
