What is the central nervous system?

• part of the nervous system composed of the brain and skin

• part of the nervous system composed of the brain and spinal cord

• part of the nervous system composed of the fingers and spinal cord

• part of the nervous system composed of the eyes and spinal cord

The peripheral nervous system involves nerve pathways that connect the spinal cord with all parts of the body; carries out the actions signaled by the brain not only for language but for movement as well.
