Easton's heart is beating rapidly, his pupils are dialated, and his mouth is dry. This response was triggered by which division of his nervous system?

• Sympathetic

• Parasympathetic

• Somatic

• Afferent

• Peripheral

division of the nervous system responsible for involuntary activity of cardiac muscle, smooth muscle, and glands

• Somatic

• Autonomic

Which of the following is NOT a function of the autonomic nervous system?

• regulating leg muscle contractions during walking

• controlling muscle movements in the stomach that push food through

• regulating heart rate and respiration rate

• controlling contraction of the arrector pili muscles (goosebumps) in the skin

Why do people get sleepy after eating a big meal?

• The sugar from food stimulates the sympathetic nervous system.

• Digestion is increased by the parasympathetic nervous system, which also relaxes the body.

• The body needs to maintain homeostasis of blood sugar concentration, so the body shuts down.

• The body switches over to the parasympathetic system because the sympathetic system has been active for too long.
