To review:

The parasympathetic pathways to the smooth muscle of the eye, bladder, and the small intestine.

Introduction:

The motor division of the autonomous nervous system has two branches, namely sympathetic and parasympathetic. The parasympathetic branch is responsible for routine body functions and the sympathetic branch is activated in response to extra metabolic requirements. Both the branches follow the two motor neuron arrangements and generally innervate the same organ but have opposing effects.
