Solution

The parasympathetic nervous system is part of the autonomic nervous system that is responsible for rest and digest activities. When the parasympathetic nerve is stimulated, it leads to various physiological responses such as:

  1. Increased saliva secretion: The parasympathetic nervous system stimulates the salivary glands to secrete more saliva. This is part of the body's preparation for digestion.

  2. Increase in digestive activity: The parasympathetic nervous system also stimulates the digestive system, increasing peristalsis and the production of digestive enzymes.

  3. Reduction in heart rate: The parasympathetic nervous system slows the heart rate. This is part of the body's return to a state of rest after a stressful situation.

However, the parasympathetic nervous system does not typically stimulate sweat gland secretion. This is usually a function of the sympathetic nervous system, which is responsible for the body's fight or flight response. Therefore, the answer to the question "Which is not an expected effect of stimulation of the parasympathetic nerve?" is "Increased sweat gland secretion".
