Question

What happens to the CNS with each drinking session?

1) It becomes more active
2) It becomes less active
3) It remains the same
4) Cannot be determined

Answer 1

During each drinking session, the Central Nervous System becomes less active, with alcohol acting as a depressant leading to reduced reaction time, alertness, and behavioral control.

Step-by-step explanation:

The Central Nervous System (CNS) becomes less active with each drinking session. Acute alcohol administration causes a variety of changes to consciousness, often starting with feelings of euphoria at low doses. However, as the dose increases, individuals tend to feel more sedated. Alcohol consumption leads to decreased reaction time, visual acuity, alertness, and behavioral control. In severe cases, excessive alcohol use may result in complete loss of consciousness and difficulty in remembering events, signs of physical dependency, and withdrawal symptoms. This illustrates that alcohol acts as a central nervous system depressant, slowing down brain function and bodily reactions.
