Verified step by step guidance
1
Understand the components of the nervous system, which is divided into the central nervous system (CNS) and the peripheral nervous system (PNS).
Recall that the central nervous system consists primarily of the brain and spinal cord, which are responsible for processing and integrating information.
Recognize that nerves and ganglia belong to the peripheral nervous system, as they transmit signals between the CNS and the rest of the body.
Identify that sensory receptors and muscles are part of the peripheral system's input and output mechanisms, not the CNS itself.
Note that the autonomic and somatic divisions are subdivisions of the peripheral nervous system, controlling involuntary and voluntary actions respectively, and are not part of the CNS.
