Verified step by step guidance1
Begin by understanding the basic structure of the nervous system, which is divided into two main parts: the central nervous system (CNS) and the peripheral nervous system (PNS).
The central nervous system consists of the brain and spinal cord. It is responsible for processing information and controlling most functions of the body and mind.
The peripheral nervous system is composed of nerves and ganglia outside of the brain and spinal cord. It connects the CNS to limbs and organs, essentially serving as a communication relay.
Recognize that the peripheral nervous system is further divided into the autonomic nervous system and the somatic nervous system. The autonomic system controls involuntary actions, while the somatic system manages voluntary movements.
Understand that the autonomic nervous system itself is divided into the sympathetic and parasympathetic nervous systems, which regulate the body's unconscious actions and maintain homeostasis.
