Which part of the brain is affected first in a drunk person:

Options

A. Cerebrum
B. Olfactory lobe
C. Cerebellum
D. Medulla oblongata

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks which part of the brain is affected first when a person consumes alcohol.

2. **Identifying the Brain Regions**: The brain is divided into several parts, but for this question, we focus on the cerebellum, which is responsible for coordination, balance, and motor control.

3. **Effects of Alcohol on the Brain**: When alcohol is consumed, it primarily affects the central nervous system. The cerebellum is one of the first areas impacted due to its role in motor control and coordination.

4. **Consequences of Cerebellum Impairment**: As alcohol consumption increases, the cerebellum’s function deteriorates. This leads to reduced self-control, impaired coordination, and emotional instability.

5. **Observing Behavioral Changes**: A person under the influence of alcohol may exhibit incoherent speech, lack of coordination, and diminished moral judgment, all of which are linked to cerebellum impairment.

6. **Conclusion**: Based on the understanding of the effects of alcohol on the brain, we conclude that the cerebellum is the first part of the brain to be affected in a drunk person.

**Final Answer**: The cerebellum.
