What division of the ans is affected by the anesthesia?

Anesthesia primarily affects the central nervous system (CNS), specifically the brain and spinal cord, by altering neural activity to induce a reversible state of unconsciousness, analgesia, and muscle relaxation. Depending on the type of anesthesia used (general, regional, or local), it can also influence peripheral nervous system functions. General anesthesia affects the entire body, while regional and local anesthesia target specific areas. Overall, the division affected depends on the anesthesia type and its intended purpose.
