ganglionic neurons.
During sympathetic activation, ________ occurs.
 
elevated blood glucose, elevated blood pressure, sweating, and elevated heart rate
A person is confronted by a dangerous dog. His heart begins to race and beat strongly, his pupils dilate, and his hairs stand up. These signs are the result of
