Which part of the brain is typically affected first by alcohol consumption?

• A. The cerebral cortex
• B. The medulla oblongata
• C. The cerebellum
• D. The hypothalamus

Answer: (A)

Verified step by step guidance

1. Understand that alcohol affects different parts of the brain in a sequence based on their sensitivity and function.
2. Recall that the cerebral cortex is responsible for higher-order functions such as judgment, reasoning, and inhibition, which are often impaired early during alcohol consumption.
3. Recognize that the medulla oblongata controls vital functions like breathing and heart rate, and is affected later at higher levels of intoxication.
4. Note that the cerebellum, which manages coordination and balance, is also affected after the cerebral cortex.
5. Conclude that the cerebral cortex is typically the first part of the brain to be affected by alcohol, leading to impaired judgment and lowered inhibitions.
