  4. Cerebral hemispheres

  5. Telencephalon
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

The hindbrain (rhombencephalon) consists of the cerebellum, pons, and medulla oblongata. These structures are located at the base of the brain and control basic life functions.

The cerebellum is concerned with

  1. Memory

  2. Vision

  3. Perception

  4. Coordination of muscular movements
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

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.

So, the correct option is 'coordination of muscular movement'.

Which of the following part of the brain controls the posture and balance of the body?

  1. Cerebrum

  2. Cerebellum

  3. Medulla oblongata

  4. All of the above
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

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.

So, the correct option is 'Cerebellum'.

  1. cerebellum

  2. pons varolii

  3. medulla oblongata

  4. thalamus.
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The cerebellum is the part of the brain responsible for coordinating voluntary movements, including hand-eye coordination. It receives input from sensory systems and adjusts motor output accordingly.

Multiple choice zoology nervous system of man parts of the brain brain and its parts brain

Which of the following statements is correct regarding cerebellum?

  1. It is a part of hindbrain

  2. It consists of two cerebellar hemisphere and a vermis

  3. Arbor vitae is present in cerebellum

  4. All of these
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

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.

Thus, the correct option is 'All of these.'

........................... coordinates the activity of picking up pencil for writing.

  1. Cerebellum

  2. Cerebrum

  3. Medulla oblongata

  4. None of the above
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

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.

Multiple choice zoology nervous system of man parts of the brain brain and its parts brain

Cerebellum of brain is concerned with

  1. controlling rapid muscular activities

  2. learning in early stages

  3. maintaining posture, orientation and equilibrium of body

  4. all of these.
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation
The cerebellum is a vital part of the brain and is primarily responsible for motor control. This includes muscle tone, equilibrium, and balance as it relates to movement. Additionally, it seems the cerebellum may actually have additional functions, including some cognitive and emotional functionals. 
So, the correct answers are 'All of these'.
Multiple choice zoology nervous system of man parts of the brain brain and its parts brain

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
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 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.

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.

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'

Which of the following connects the cerebrum of brain and brain stem?

  1. Cerebral peduncles

  2. Corpora bigemina

  3. Corpora quadrigemina

  4. None of the above
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation
  • The cerebral peduncles (also known as the cerebral crus) are the part of the midbrain that links the brainstem and the cerebrum of the brain. 
  • They are the most anterior structure in the midbrain and contain the large ascending and descending tracts that run to and from the cerebrum. Hence, Cerebral peduncles connect the cerebrum of brain and brain stem.
    • So, the correct answer is 'Cerebral peduncles'.
