Question

Posture and balance of the body is controlled by

• A. cerebrum
• B. cerebellum
• C. medulla
• D. pons

Answer 1

The correct option is B

cerebellum

The correct option is B

Explanation for correct answer:

1. The brain is one of the human body's largest and most complicated organs.
2. Its root word means "small brain," as it is located near the brainstem.
3. The area of the brain responsible for coordinating postures and voluntary movements of skeletal muscles has a latin origin that means "small brain," although it actually plays an important role in the hindbrain.
4. Any irregularity or damage in this area can lead to problems with posture, balance, and uncoordinated voluntary motor muscles.
5. The cerebrum is the most significant and largest region of the human brain.
6. There are three regions of the cerebral cortex: sensory, motor, and limbic.
7. Sensory regions are in charge of sensory information perception, whereas motor areas are in charge of voluntary movement execution.
8. The cerebellum accounts for only 10% of the total volume of the brain, yet it contains 50-80% of the brain's neurons.

Explanation for incorrect answer:

Option A:

1. Few significant integrative processes, such as memory, personality traits, and intelligence, rely on cerebral cortical association areas.
2. As a result, the cerebrum collaborates with other areas of the brain to improve brain function.

Option C:

1. The limbic system promotes a variety of emotions such as anger, affection, joy, fear, pain, and so on.
2. The medulla oblongata is made up of ascending sensory and descending motor tracts.
3. The cardiovascular central regulator regulates pulse and blood vessel diameter.

Option D:

1. This area also regulates breathing rhythms and other important processes.
2. The cerebellum appears to be a small, distinct region of the brain.
3. However, it is considerably larger and is separated into two cortex, comparable to the cerebrum, namely the cerebellar cortex and cerebellar nuclei.

Final answer:

The posture and balance of the body are controlled by the cerebellum.
