1.
The cerebellum is the largest part of the _________.
Correct Answer
C. Hindbrain
Explanation
The cerebellum constitutes the largest part of the hindbrain. (http://www.bartleby.com/107/187.html)
2.
The cerebellum originates from the dorsal aspect of the brain stem and overlies the ______ ventricle.
Correct Answer
D. Fourth ventricle
Explanation
The cerebellum constitutes the largest part of the hindbrain. It lies behind the pons and medulla oblongata; between its central portion and these structures is the cavity of the fourth ventricle. (http://www.bartleby.com/107/187.html)
3.
Three fiber bundles called peduncles connect the cerebellum to the brain stem. On these tracts, information runs in both directions, with all messages sent and received by the cerebellum traveling on these fibers. Which of the below is not one of the three cerebellar peduncles?
Correct Answer
D. Flocculonodular lobe
Explanation
The flocculonodular lobe is not one of the three cerebellar peduncles. The cerebellar peduncles are fiber bundles that connect the cerebellum to the brainstem, allowing for the transmission of information in both directions. The three cerebellar peduncles are the superior, middle, and inferior peduncles. The flocculonodular lobe, on the other hand, is a region of the cerebellum that is involved in balance and eye movement control, but it is not one of the peduncles.
4.
Damage to the cerebellum does not cause disorders of...
Correct Answer
E. Paralysis
Explanation
Because of this fine-tuning function, damage to the cerebellum does not cause paralysis, but instead produces disorders in fine movement, equilibrium, posture, and motor learning.[2] (http://en.wikipedia.org/wiki/Cerebellum)
5.
The functions of the cerebellum are entirely motor and it operates at an ___________ level.
Correct Answer
B. Unconscious
Explanation
The functions of the cerebellum are entirely motor and it operates at an unconscious level. It controls the maintenance of equilibrium (balance), influences posture and muscle tone, and coordinates movement.
6.
The vermis is...
Correct Answer
A. Thin structure that separates the two hemispheres of the cerebellum.
Explanation
The vermis is a midline structure within the cerebellum that runs longitudinally, dividing it into two symmetrical hemispheres. It plays a crucial role in coordinating and integrating motor movements and balance.
7.
The folds of the cerebellum are called...
Correct Answer
E. Folia
Explanation
The surface of the cerebellum is highly convoluted, the folds, or folia, being oriented approximately transversely.

8.
The fissures of the cerebellum are landmarks that are used to divide it anatomically into _____ lobes.
Correct Answer
C. Three
Explanation
Some of these fissures are landmarks that are used to divide the cerebellum anatomically into three lobes.
9.
Anatomically, the cerebellum is divided into what three lobes?
Correct Answer
A. Anterior, posterior and flocculonodular
Explanation
Anatomically, the cerebellum is divided into anterior, posterior and flocculonodular lobes.
10.
The flocculus and nodule together form the...
Correct Answer
D. Flocculonodular lobe
Explanation
On the superior surface, the deep primary fissure separates the relatively small anterior lobe from the much larger posterior lobe. On the underside, the conspicuous posterolateral fissure demarcates the location of small regions of the hemisphere (the flocculus) and vermis (the nodule), which together form the flocculonodular lobe.
11.
The cerebellum basically consists of an outer layer of grey matter called the __________ ______.
Correct Answer
cerebellar cortex
cerebellarcortex
cerebelar cortex
Explanation
The cerebellum basically consists of an outer layer of grey matter called the cerebellar cortex.
12.
The cerebellum possess an inner core comprised of _____ ______.
Correct Answer
white matter
whitematter
wite matter
Explanation
The correct answer is "white matter". The cerebellum is a region in the brain that contains an inner core made up of white matter. White matter refers to the bundles of nerve fibers that are coated in myelin, a fatty substance that helps in the transmission of signals between different regions of the brain. These nerve fibers allow for communication and coordination of movements within the cerebellum and between the cerebellum and other parts of the brain.
