Carolyn was enjoying an evening walk around her neighborhood pond. As she walked over the wooden bridge, she heard a loud splash. She noticed a 4-foot alligator right under the bridge. Immediately, her pupils dilated, she began to perspire, and her heart rate accelerated. These changes are most closely related to the function of the
cerebellum
hippocampus
parasympathetic nervous system
parietal lobe
sympathetic nervous system
The sympathetic nervous system is used to excite the body during stressful or dangerous situations. It will increase heart rate, dilate lungs and pupils, and sends oxygen to major muscle groups.
