Which of the following regions of the brain is incorrectly paired with it’s function? A. Cerebellum- language comprehension B. Corpus callosum- communication between the left and right cerebral hemispheres C. Cerebrum- calculation and contemplation D. Medulla oblangata- homeostatic control
Option A. 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.
