Cerebellar hemispheres are the largest regions of the cerebellum. The cerebellar hemispheres are two divisions of the cerebellum on either side of the vermis. They are functionally subdivided into lateral and medial portions. It is a part of the hindbrain. The arbor vitae is the cerebellar white matter, so called for its branched, tree-like appearance. In resembles like a fern and is present in both cerebellar hemispheres. It brings sensory and motor information to and from the cerebellum.

Coordination between various muscles needed for picking up the pencil, orienting it correctly etc are controlled by the cerebellum of the brain, a part of the hind brain.

The spinal cord is a long bundle of nervous tissue that originates from the medulla oblongata to the lumbar region of the vertebral column. It connects brain to peripheral nerves in the body. It acts as means of communication. 

The cerebellum is located down to the occipital lobe of the cerebrum. The cerebellum is the vital part of the brain that controls the motor movements of the body. Its functions include coordinated movement, balance, posture, speech, etc. Thus in this case, if the cerebellum is damaged the person won't be able to stand or walk properly. So, the correct answer is option C.

The cerebellum is located down to the occipital lobe of the cerebrum. The cerebellum is the vital part of the brain that controls the motor movements of the body. Its functions include coordinated movement, balance, posture, speech, etc. Thus in this case of imbalance in riding a bicycle, or not walking is straight line can be caused by dizziness and improper functioning of the cerebellum. So, the correct answer is option C.

The cerebellum is located down to the occipital lobe of the cerebrum. The cerebellum is the vital part of the brain that controls the motor movements of the body. Its functions include coordinated movement, balance, posture, speech, etc. Thus his movement and speech becomes unbalanced and uncontrolled. Thus, the correct answer is option B.

Depending on the plane of movement, the endolymph flowing within the semicircular canals stimulates the appropriate movement hair cells. 

The cerebellum is a part of the brain. It controls the motor control. It receives information from the sensory systems, spinal cord and other parts of the brain and regulates the motor movements. It coordinates voluntary movements such as posture, balance, coordination and speech. So. if a person cannot walk in a straight line or cannot balance a ride on a bicycle, it means cerebellum is not working properly.
