Alcohol primarily affects the central nervous system (CNS), which includes the brain and spinal cord. The CNS is essential for processing sensory information, coordinating movement, and managing bodily functions. Alcohol acts as a depressant, impacting neurotransmitter systems and altering brain function. This can lead to slowed reaction times, impaired judgment, and a decrease in motor coordination, all indicative of its significant influence on the central nervous system.

The fact that alcohol affects the CNS more than it impacts the peripheral or somatic nervous systems highlights its role in altering mental states and behavior, as well as affecting vital autonomic processes. The cerebellum, while it plays a role in coordination and balance, is a part of the CNS; therefore, its functions would also reflect the broader impact of alcohol on the central nervous system as a whole.
