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

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'

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

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.

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

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.

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

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'.

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

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'.
