parasympathetic stimulation are conservation and restoration of energy.
The parasympathetic nervous system does not have alpha and beta receptor

6-12. EFFECTS PRODUCED BY THE PARASYMPATHETIC NERVOUS SYSTEM
The parasympathetic physiological activity on the organs is generally the opposite
of the sympathetic with a few exceptions. The effect of the parasympathetic nervous
system effects on some areas of the body are listed below:
a. Eye (Pupil). Contraction of the pupil (miosis) is produced by parasympathetic
b. Heart. The parasympathetic nervous system produces a decrease in heart
rate and a slight decrease in the contraction strength of the heart.
Bronchi. The bronchi are contracted by parasympathetic stimulation.
