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.

The branched tree-like structure/tree of life present in the cerebellum is

  1. Arbor vitae

  2. Arborial

  3. Archenteron

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

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. 

Hence, the correct answer is 'Arbor vitae'

Arbor vitae is

  1. Tree-like structure in cerebrum

  2. Tree of life in cerebellum

  3. End part of spinal cord

  4. Branched dendrites of a neuron
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Arbor vitae, meaning 'tree of life', refers to the branching white matter pattern seen in a cross-section of the cerebellum. It is named for its resemblance to a tree.

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
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

The cerebellum is essential for the coordination of voluntary muscle activity, including complex tasks like hand-eye coordination. It ensures movements are smooth and precise.

Arbor vitae is

  1. Grooves and sulci of cerebral hemispheres

  2. Rounded elevation behind in- fundibulum

  3. Thick nerve tracts linking cerebrum with medulla oblongata

  4. Branched white matter inside cerebellum
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Arbor vitae is the specific term for the white matter tracts within the cerebellum that branch out like a tree. It is distinct from the gray matter of the cerebral cortex.

Pons, cerebellum and medulla constitute

  1. Fore brain

  2. Mid brain

  3. Hind brain

  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.
