The cerebellum is an area of the mind that assumes an imperative job in engine control. It might likewise be associated with some intellectual capacities, for example, consideration and dialect, and in controlling trepidation and joy reactions, however, its development related capacities are the most firmly settled.

Hindbrain has 3 parts - (1) pons, (2) cerebellum, (3) medulla oblongata. Diencephalon is a small and posterior part of forebrain. It is covered by cerebrum. It consists of thalamus, hypothalamus, epithalamus and metathalamus.

a) Cerebrum serves to receive sensory inputs, to bring about integration before commanding voluntary motor responses, to coordinate the activities of another part of the brain, and to carry out higher thought processes for learning, memory, language and speech. 

The hindbrain includes the cerebellum, the pons and the medulla oblongata, which function collectively to support vital bodily processes. The medulla is joined to the spinal cord and controls unconscious, essential body functions such as breathing, swallowing, blood circulation and muscle tone. Located above the medulla is the pons, which receives information from visual areas to control eye and body movements and also plays a role in controlling patterns of sleep and arousal. Information is relayed from the pons to the cerebellum to control the coordination of muscular movements and maintain equilibrium.

The cerebellum receives information from the sensory systems, the spinal cord, and other parts of the brain and then regulates motor movements. The cerebellum coordinates voluntary movements such as posture, balance, coordination, and speech, resulting in smooth, balanced muscular activity.

The cerebellum is the region of the hind brain. The cortex of cerebellum is made up of grey matter which is external to the white matter. The white matter projects outside and forms a branching pattern of a tree, which is called the Arbor Vitae or the tree of life. It is required for the coordination of various movements of the body. It also allows the cerebellum to communicate with the parts of the brain. 

The cerebellum controls the timing and pattern of the muscle activation during movement. The main function of the cerebellum receives information from the sensory system, the spinal cord, and other parts of the brain and then regulates motor movements. The cerebellum coordinates voluntary movements such as posture, balance, coordination, and speech, resulting in smooth and balanced muscular activity.

The cerebellum controls the posture and balance in the body because it receives the information from the inner ear, eyes, muscles etc which estimates the axis of the body and send signals to corresponding muscles for postural correction.

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.

The cerebellum is made up of two lateral lobe and a large vermis lobe which is divided into nine segments. It is associated with the fastigial nucleus. It is concerned with the regulation of the regulation of the muscle tone for posture and locomotion. 

The ventricles are the hollow spaces in the brain that are lined with the choroid plexus and is filled with the cerebrospinal fluid. The lateral ventricles are located in the hemispheres of the telencephalon (cerebrum). The 3rd ventricle is located in the centre of the diencephalon. The 4th ventricle is located in the centre of the metencephalon (between pons and cerebellum). The cerebral aqueduct connects the 3rd and 4th ventricle and it is located in the centre of the mesencephalon (midbrain). The cerebellum does not have any ventricle.

Cerebellum is the  part of the brain which is responsible for balancing the body. It helps in coordination of right and left interpretation done by the central nervous system. When the cerebellum, gets damage the coordination between several movements is lost.

So, the correct answer is 'He will be unable to coordinate and stand properly'

The cerebellum is a small region at the back of the brain. It is the largest part of hind brain. The cerebellum controls smooth, coordinated movements, helps to maintain muscle tone, posture, and balance.

The region of the brain that connects the cerebrum to the spinal cord is called as brainstem. It is made up of midbrain, medulla oblongata and pons. It is a site where many cranial nerves are located. The brainstem is involved in te relay of signals between the spinal cord and brain. It also controls the working of the PNS. Thus the correct answer is option B.
