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

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.

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'.

The part of human brain that is responsible for hand-eye coordination is

  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'.

Spinal cord originates from cerebellum.

  1. True

  2. False
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

The spinal cord is a long bundle of nervous tissue that originates from the medulla oblongata to the lumbar region of the vertebral column. It connects brain to peripheral nerves in the body. It acts as means of communication. 

Thus, the correct answer is option B.
