Identify the INCORRECT match of brain region with its general function. A. Limbic system – balance & posture B. Medulla Oblongata – visceral control center C. Insula – taste D. Temporal lobe – hearing E. Wernicke’s area – understanding language
The correct answer and explanation is:
Correct Answer: A. Limbic system – balance & posture
Explanation:
The limbic system is incorrectly matched with the function of balance and posture. The limbic system is a complex set of brain structures that includes the hippocampus, amygdala, thalamus, hypothalamus, and parts of the cerebral cortex. Its primary roles include emotion regulation, memory processing, motivation, and aspects of behavior. It is not involved in balance or posture.
Balance and posture are primarily controlled by the cerebellum, which is located at the back of the brain beneath the occipital lobe. The cerebellum receives sensory input from the inner ear, eyes, and muscles to help coordinate movement and maintain equilibrium. Therefore, linking balance and posture with the limbic system is incorrect.
On the other hand, the other options are correctly matched:
- B. Medulla Oblongata – visceral control center: The medulla oblongata, part of the brainstem, regulates vital autonomic functions such as heart rate, respiration, and digestion. It serves as a control center for visceral (internal organ) activities.
- C. Insula – taste: The insular cortex, or insula, is involved in processing taste information. It also plays roles in emotional responses and awareness of bodily states.
- D. Temporal lobe – hearing: The temporal lobe contains the primary auditory cortex, which processes sound information. It is essential for hearing, language comprehension, and memory formation.
- E. Wernicke’s area – understanding language: Wernicke’s area, typically located in the left hemisphere of the brain, is crucial for language comprehension. Damage to this area can lead to Wernicke’s aphasia, where individuals may produce fluent but nonsensical speech and have difficulty understanding language.
In conclusion, option A is incorrect because the limbic system is not involved in balance and posture. That function is instead carried out by the cerebellum.
