However, they are not divisions of the autonomic nervous system itself; rather, they are parts of the central nervous system that help regulate autonomic processes.

The somatic nervous system is responsible for voluntary muscle movements and sensory information, while the endocrine system involves the regulation of hormones. These terms refer to different systems in the body and do not accurately describe the components of the autonomic nervous system.
