What would happen to the person if cerebellum of his brain is damaged?

  1. He will lose his memory power

  2. He will not be able to swallow food properly

  3. He will be unable to coordinate and stand properly

  4. He will lose his power of vision and hearing
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

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.

If a person cannot walk in a straight line or cannot balance a ride on bicycle, probably which part of his brain is not working

  1. Cerebrum

  2. Cranium

  3. Cerebellum

  4. Hypothalamus

C Correct answer
Explanation

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.

If cerebellum of man gets damaged, his movement becomes

  1. Shaky and speech becomes defective

  2. Unbalanced walk, uncontrolled and defective speech, intention tremor

  3. Jerky and defective speech

  4. Jerky and walked uncontrolled

B Correct answer
Explanation

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.

Which of the following nerve helps in maintaining the equilibrium of body?

  1. Trochlear

  2. Abducens

  3. Auditory

  4. Facial
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

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

The static head position is sensed by the vestibule, specifically, its utricle and saccule, which contain the hair cells. 
Different head positions produce different gravity effects on these hair cells. The hair cells for both position and movement create nerve impulses. These impulses travel over the vestibulocochlear nerve (auditory nerve) to synapse in the brain stem, cerebellum, and spinal cord.

If a person cannot walk in a straight line or cannot balance a ride on bicycle, probably which part of his brain is not working properly? 

  1. Cerebrum

  2. Cranium

  3. Cerebellum

  4. Hypothalamus
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

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.

Vermis is

  1. A tiny worm

  2. Cavity of medulla

  3. The large median lobe of cerebellum in mammals

  4. A portion of mid brain
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

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. 

Hence, the correct answer is 'The large median lobe of cerebellum in mammals'

The part of brain without its ventricle is

  1. Cerebrum

  2. Cerebellum

  3. Medulla

  4. Diencephalon
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

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.

Hence, the correct answer is 'Cerebellum'

What would happen to the person if cerebellum of his brain is damaged?

  1. He will lose his memory power

  2. He will not be able to swallow food properly

  3. He will be unable to coordinate and stand properly

  4. He will lose his powers ofvision and hearing
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

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'

Which part of the human brain controls balance, posture and coordination?

  1. Cerebrum

  2. Cerebellum

  3. Medulla oblongata

  4. Thalamus

  5. Hypothalamus
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

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 brainstem is made up of

  1. Midbrain, Pons, Cerebellum

  2. Midbrain, Pons, Medulla oblongata

  3. Forebrain, Pons, Cerebellum

  4. Cerebellum, Cerebrum, Medulla oblongata
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

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.
