Correct Option: C

The cerebellum is concerned with

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

  1. Memory

  2. Vision

  3. Perception

  4. Coordination of muscular movements

Show answer
Correct Option: D
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?

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

  1. Cerebrum

  2. Cerebellum

  3. Medulla oblongata

  4. All of the above

Show answer
Correct Option: B
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

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

  1. cerebellum

  2. pons varolii

  3. medulla oblongata

  4. thalamus.

Show answer
Correct Option: A

Which of the following statements is correct regarding cerebellum?

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

  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

Show answer
Correct Option: D
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.

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

  1. Cerebellum

  2. Cerebrum

  3. Medulla oblongata

  4. None of the above

Show answer
Correct Option: A
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.

Cerebellum of brain is concerned with

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

  1. controlling rapid muscular activities

  2. learning in early stages

  3. maintaining posture, orientation and equilibrium of body

  4. all of these.

Show answer
Correct Option: D
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.

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

  1. True

  2. False

Show answer
Correct Option: B
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.
