Basic Functions Of Cerebellum! Trivia Quiz!
The cerebellum is a part of the brain located in a region called hindbrain. The cerebellum is concerned with the control of movement and posture. It coordinates balance, speech and also maintain smooth and skeletal muscle activity. Evolutionarily, the cerebellum is regarded as a old part of the body. Take this quiz about the cerebellum now!

Which of these is not at the front of the cerebellum?
- A.
Medulla
- B.
Third ventricle
- C.
Pons
- D.
Fourth ventricle
Correct Answer
B. Third ventricleExplanation
The cerebellum is a part of the brain located at the back of the head, below the cerebrum. It is responsible for coordinating voluntary movements, balance, and posture. The medulla, pons, and fourth ventricle are all structures that are located at the front of the cerebellum. However, the third ventricle is not located at the front of the cerebellum. The third ventricle is a fluid-filled cavity in the brain that is located between the two halves of the thalamus.Rate this question:

Which of these strusctures is located at the base of the cerebellum?
- A.
Ventricles
- B.
White matter
- C.
Arteries
- D.
Cerebellar nuclei
Correct Answer
C. ArteriesExplanation
The correct answer is "Arteries." The arteries are located at the base of the cerebellum. They supply blood to the cerebellum, which is responsible for coordinating movement and maintaining balance.Rate this question:

What are the numerous functioning modules in the cerebellum called?
- A.
Foramen
- B.
Channels
- C.
Ridges
- D.
Microzones
Correct Answer
D. MicrozonesExplanation
The numerous functioning modules in the cerebellum are called microzones. These microzones are small regions within the cerebellum that are responsible for specific functions such as motor control, coordination, and balance. Each microzone consists of a group of neurons that work together to process and integrate sensory information and coordinate movements. These microzones play a crucial role in maintaining proper motor function and ensuring smooth and coordinated movements.Rate this question:

Where is the cerebellum located?
- A.
Inferior lobe
- B.
Anterior thorax
- C.
Superior lobe
- D.
Posterior cranial fossa
Correct Answer
D. Posterior cranial fossaExplanation
The cerebellum is located in the posterior cranial fossa. It is a part of the brain that is responsible for coordinating voluntary movements, maintaining balance, and controlling posture. It is situated below the occipital lobes of the cerebral cortex and behind the brainstem. The posterior cranial fossa provides protection and support to the cerebellum, along with other structures such as the brainstem and the fourth ventricle.Rate this question:

Which of these brain imaging procedures can be used to research the function of cerebellum?
- A.
Functional magnetic resonance imaging
- B.
Commuted tomography
- C.
Positron emission tomography
- D.
Magnetic resonance imaging
Correct Answer
A. Functional magnetic resonance imagingExplanation
Functional magnetic resonance imaging (fMRI) is a brain imaging procedure that can be used to research the function of the cerebellum. fMRI measures changes in blood flow and oxygenation levels in the brain, which can indicate neural activity. By analyzing these changes, researchers can study how the cerebellum is involved in various cognitive processes and motor functions. This makes fMRI a valuable tool for investigating the role of the cerebellum in different tasks and behaviors.Rate this question:

Which of these is not a function of cerebellum?
- A.
Feedforward processing
- B.
Divergence and convergence
- C.
Plasticity
- D.
Illustrative learning
Correct Answer
D. Illustrative learningExplanation
The cerebellum is responsible for coordinating voluntary movements, maintaining posture and balance, and motor learning. It is involved in feedforward processing, where it predicts and prepares for upcoming movements. It also plays a role in divergence and convergence, which refers to the integration of sensory information from different sources. Plasticity is the ability of the cerebellum to adapt and change in response to experience. However, illustrative learning is not a recognized function of the cerebellum.Rate this question:

Which of these refers to the synapse between parallel fibers and purkinje cells?
- A.
Convergence
- B.
Plasticity
- C.
Modularity
- D.
Divergence
Correct Answer
B. PlasticityExplanation
Plasticity refers to the ability of the synapse between parallel fibers and Purkinje cells to change and adapt over time. This can include changes in the strength of the synapse, the number of synapses, or the overall structure of the synapse. Plasticity is important for learning, memory, and the overall function of the cerebellum, where parallel fibers and Purkinje cells are found.Rate this question:

Which of these diseases affects the cerebellum the most?
- A.
Parkinson's disease
- B.
Alzheimer's disease
- C.
Prion disease
- D.
Hughtington's disease
Correct Answer
C. Prion diseaseExplanation
Prion disease affects the cerebellum the most. Prion diseases are a group of rare, progressive, and fatal neurodegenerative disorders that are caused by abnormal proteins called prions. These abnormal proteins accumulate in the brain and cause damage to nerve cells, particularly in the cerebellum. The cerebellum is responsible for controlling coordination and balance, so when it is affected by prion disease, it can lead to problems with movement, coordination, and balance. Parkinson's disease, Alzheimer's disease, and Huntington's disease primarily affect other areas of the brain and have different symptoms.Rate this question:

Which of these refers to the cerebellum?
- A.
Rhombencephalon
- B.
Diancephalon
- C.
Metencephalon
- D.
Mesencephalon
Correct Answer
C. MetencepHalonExplanation
Metencephalon - This is a more specific part of the brain development structure and it includes the pons and the cerebellum itself. Therefore, it directly refers to the cerebellum as part of its composition.Rate this question:

Which of these is not a type of axon in the cerebellum?
- A.
Mossy fibers
- B.
Climbing fibers
- C.
Agranular fibers
- D.
Parallel fibers
Correct Answer
C. Agranular fibersExplanation
The cerebellum consists of different types of axons, including mossy fibers, climbing fibers, and parallel fibers. Agranular fibers, however, are not a type of axon found in the cerebellum. Therefore, the correct answer is Agranular fibers.Rate this question:
