Question

If a person cannot walk in a straight line or cannot balance a ride on a bicycle, probably which part of his brain is not working.
A. Cerebrum
B. Cranium
C. Cerebellum
D. Hypothalamus

Answer 1

Hint: Cerebellum part of the brain is not functioning properly if a person cannot maintain the balance of the body. The motor function such as spinal cord and sensory system that regulates the motor movement control by the Cerebellum part of the brain. It also helps in the speech, posture and balance coordination of the body.

Complete answer:
The location near the brainstem is located as a major structure of the hindbrain known as cerebellum. The Cerebellum responsible for the voluntary movements such as postures, balance and motor skills of the body. In the Cerebellum motor movements regulate in the part of the brain and spinal cord by receiving the information from the sensory system.
Cerebellum contains roughly half part of the neurons present in the brain and total 10% of the total weight also consists of the small portion of the brain. Tremors, slower movements and lack of balance rise up with the cause of Cerebellum damage. Damage also affects the unsteady and halting complex physical tasks of the body. The major part of the Cerebellum – vestibulocerebellum, cerebrocerebellum, spin cerebellum and vestibular cerebellum that’s present in the lateral hemisphere part of the largest division present in the brain.

Therefore the correct option is (C).

Note: The location of the Cerebellum located behind the upper part of the brain stem and made of two halves (where the spinal cord meets the brain). It plays a vital role in learning motor behaviors. Before existing the human cerebellum was also present in the animal’s too, also known as the older portion of the brain that helped the evolutionary speaking.
