B. He will not be able to swallow food properly
C. He will be unable to coordinate and stand properly
D. He will lose his power of vision and hearing

Answer 1

Hint: The brain has three parts, cerebrum, cerebellum and medulla oblongata. Thus, the cerebellum is the part of the brain that is located in the hindbrain region. The cerebellum controls the posture and the balance of the body.

Complete step by step answer: Functions of the cerebellum –
-The cerebellum modulates and reorganizes the motor commands. However, the cerebellum does not initiate the movements of the body. The most important function of the cerebellum is to coordinate the locomotor activity of the body. These activities are actually initiated by the impulses that arise from the motor area which is present in the forebrain.
-The cerebrum and cerebellum coordinate together to cause movement. The cerebellum produces unconscious directions and the cerebrum produces conscious instructions to determine how and when to move the body parts. The cerebellum is very important for controlling rapid muscular activities. The cerebellum controls all the involuntary actions of the body directly.
-Thus, based on the above information, if the cerebellum of a person is damaged then he will be unable to coordinate and stand properly.
Hence, the correct answer is option (C).
Note: The second largest part of the brain is the cerebellum. It is a part of the hindbrain of the rhombencephalon. The hindbrain consists of two parts, the metencephalon, and the myelencephalon. The cerebellum is the part of the metencephalon. The cerebellum has two hemispheres. The outermost layer of the cerebellum is the foliage of grey matter, whereas, the inner layer is a white layer of arborvitae.
