  • Answer
ANS: C
Arousal is mediated by the reticular activating system, which regulates aspects of attention and information processing and maintains consciousness. The cerebral cortex affects movement. The medulla oblongata controls things such as hiccups and vomiting. The cingulate gyrus plays other roles in response.
