Question

parasympathetic stimulation
increases sweating.
increases gastric motility.
dilates blood vessel to the skin.
dilates the pupil.
increases heart rate.

Explanation:

The parasympathetic nervous system is often referred to as the "rest - and - digest" system. When stimulated:

• Sweating is mainly regulated by the sympathetic nervous system, so parasympathetic stimulation does not increase sweating.
• It promotes digestive functions, and increasing gastric motility is part of the digestive - promoting role.
• Blood vessel dilation to the skin is more related to other factors (e.g., temperature regulation in some cases, but not a primary parasympathetic effect).
• Pupil dilation is a sympathetic effect (parasympathetic causes pupil constriction).
• Increasing heart rate is a sympathetic effect (parasympathetic decreases heart rate).

Answer:

increases gastric motility.
