If medulla oblongata is destroyed then which of the following functions will be affected?

  1. No thermoregulation

  2. No vision

  3. No response when prickled with needles

  4. No memory
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

The medulla oblongata controls vital autonomic functions. If destroyed, the body loses the ability to maintain these involuntary processes. The option regarding the prick reflex is the most commonly cited consequence in this context.

The posture and equilibrium is maintained by which part of the brain?

  1. Hypothalamus

  2. Medulla oblongata

  3. Cerebrum

  4. Cerebellum
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation
A. The function of the hypothalamus is to link the nervous system to the endocrine system via the pituitary gland.
B. The medulla oblongata is a part of the brain and it is a center for respiration and circulation. Sensory and motor neurons from the forebrain and midbrain travel through the medulla.
C. The cerebrum or cortex is the largest part of the human brain, associated with higher brain function such as thought and action.
D. The cerebellum (back of brain) is located at the back of the head. Its function is to coordinate voluntary muscle movements and to maintain posture, balance, and equilibrium.
So, the correct answer is "Cerebellum".

Motor learning is related to .............

  1. Cerebellum

  2. Cerebrum

  3. Pons

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

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.


So, the correct option is 'Cerebellum'.

Which of the following is not a structure in the hindbrain?

  1. Medulla oblongata

  2. Thalamus

  3. Cerebellum

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

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.

Which part of the brain control the posture and balance of the body?

  1. Cerebrum

  2. Medulla

  3. Cerebellum

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

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. 

b) Medulla oblongata consists of reflex centres that control heartbeat, blood vessel diameter and rhythm of breathing as well as other vital functions. 
c) Cerebellum serves to coordinate the voluntary movements of skeletal muscles as well as posture, balance and equilibrium. The vestibulocerebellum receives sensory input from vestibular apparatus and visual area and the output is sent to vestibular nuclei in the brain stem, thereby controlling posture and equilibrium. 

d) Pons serves as a connector between spinal cord and brain and between different parts of the brain, it also controls breathing.

So, the correct answer is option C.

Reflexes for maintaining vital functions like blood pressure are located in

  1. Hindbrain

  2. Midbrain

  3. Forebrain

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

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.

Part of the brain concerned with the muscular movement is 

  1. Cerebellum

  2. Thalamus

  3. Hippocampus

  4. Temporal lobe of cerebrum
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

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.

Part of mammalian brain controlling muscular coordination, equilibrium and posture is

  1. Cerebrum

  2. Corpus callosum

  3. Medulla oblongata

  4. Cerebellum
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

The cerebellum is the region of the brain responsible for fine-tuning motor movements, maintaining equilibrium, and regulating posture. The cerebrum handles higher cognitive functions, while the medulla oblongata controls autonomic functions like breathing.

Part of brain controlling balance and coordination is

  1. Cerebrum

  2. Medulla oblongata

  3. Hypothalamus

  4. Cerebellum

  5. Corpora quadrigemina
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

The cerebellum is the primary brain structure responsible for coordinating voluntary movements and maintaining balance. Other options like the hypothalamus and medulla have different primary functions.

Coordination of hand-eye or voluntary muscle activity is connected with

  1. Cerebrum

  2. Cerebellum

  3. Medulla oblongata

  4. Crura cerebri
