A 30-year-old woman tells the nurse that she has been very unsteady and has had difficulty in maintaining her balance. Which area of the brain that is related to these findings would concern the nurse?
Brainstem
Cerebellum
Extrapyramidal tract
Thalamus
The Correct Answer is C
A. The brainstem controls basic life functions but is not primarily responsible for balance.
