Which part of the brain is affected first in a drunk person :[Bihar-2004]a)Cerebrumb)Olfactory lobec)Cerebellumd)Medulla oblongataCorrect answer is option 'C'. Can you explain this answer?

Question

Answer

When a person gets addicted to alcohol, many serious health problems can occur due to consumption of alcohol. The first part of brain to be affected first is Cerebellum. The will power and self control of the person gets reduced. Control over emotions and moral sense also gets reduced. Loss of muscle coordination also occurs as cerebellum is affected. As a result, speech becomes incoherent. Inflammation of axons also occur which causes neuritis.

Answer

Answer

The correct answer is option 'C' - the cerebellum.

Explanation:
The cerebellum is the part of the brain that is affected first in a drunk person. The cerebellum is located at the back of the brain, just above the brainstem. It is responsible for coordinating movement, balance, and posture.

When a person consumes alcohol, it enters the bloodstream and eventually reaches the brain. Alcohol affects the central nervous system and has a depressant effect on the brain. It affects various parts of the brain, but the cerebellum is particularly sensitive to the effects of alcohol.

The cerebellum is responsible for coordinating the movements of the muscles in the body. It receives signals from the sensory systems and sends signals to the muscles to control movement. When a person is drunk, the cerebellum's ability to coordinate movement is impaired.

Alcohol affects the cerebellum by interfering with the communication between the nerve cells (neurons) in this region. It inhibits the release of certain neurotransmitters, such as gamma-aminobutyric acid (GABA), which is involved in inhibiting brain activity. This leads to a decrease in the functioning of the cerebellum, resulting in impaired coordination and balance.

Drunk individuals often have difficulty walking in a straight line, maintaining balance, or performing fine motor tasks. They may stumble, have slurred speech, and have poor coordination. These symptoms are indicative of cerebellar dysfunction due to alcohol's effects on this brain region.

In summary, the cerebellum is the part of the brain that is affected first in a drunk person. Alcohol impairs its functioning, leading to coordination and balance problems. Understanding the effects of alcohol on the brain can help in the prevention and treatment of alcohol-related problems.
