Question

Which of the following regions of the brain is incorrectly paired with its function?
A. Corpus callosum- communication between the left and right cerebral cortices
B. Cerebrum- calculation, and contemplation
C. Medulla oblongata- homeostatic control
D. Cerebellum- language comprehension

Answer 1

Hint: The brain is the most complex and sensitive organ of the human body. The brain is composed of three main regions called cerebrum, cerebellum, and brainstem. The cerebrum controls emotions and movement. The cerebellum performs coordination and maintains body posture. The brainstem is majorly involved in involuntary functions.

Complete answer:
The brain is made up of several complex regions that work together to perform the activities which we are able to do in our daily life. The brain is divided into two hemispheres namely right and left cerebral cortices. Both of these cortices are connected by a thick band of nerve fibers called the corpus callosum. It assists in communication between the two cortices.

The cerebrum is the largest region of the brain and is the main functional center. It consists of ridges and grooves that form the gyri and sulci of the brain respectively. The cerebrum is involved in all the major activities of the brain such as controlling movement and cognitive processes. Memory, thinking, emotions, movement of limbs and body, language processing, etc. is regulated by the cerebrum.
The medulla oblongata is the base region of the brainstem. It consists of the cardio-regulatory center. This means that it controls the involuntary actions of the heart. The beating of the heart, pumping of blood, etc. is controlled by the medulla oblongata. The baroreceptors in the medulla oblongata regulate the blood pressure of the body which is a homeostatic mechanism.
The cerebellum is the posterior region of the brain. It is involved in the regulation of body posture. It helps maintain the balance of the body. Also, the cerebellum is the center for skill development. Language comprehension is not the function of the cerebellum.
So, the correct answer is option D.

Note: The Wernicke’s area and the Broca’s area are two regions of the temporal side of the cerebral cortex. Both hemispheres contain these regions. But the left side has a more pronounced effect on these regions. Wernicke’s area is involved in understanding language that is language comprehension. On the other hand, Broca’s area is involved in language production and processing.
