A lesion to which brain region would result in a lack of coordinated movement?
Correct answer: D. The cerebellum
- A. The left temporal lobe
- B. The hypothalamus
- C. The medulla oblongata
- D. The cerebellum
Explanation
The correct answer is D) The cerebellum, because its primary function is to regulate motor movements, coordination, posture, and balance, so a lesion here directly results in a lack of coordinated movement (ataxia) . The other options are incorrect: The left temporal lobe is mainly involved in hearing, memory, and language comprehension; the hypothalamus controls vital functions like hunger, thirst, and body temperature; and the medulla oblongata regulates autonomic functions such as breathing, heart rate, and blood pressure.
