Summary Introduction

To review:

The cranial nerve pathway along which postganglionic fibers are carried to the target organs.

Introduction:

The autonomic nervous system innervates the internal organs by two divisions, namely sympathetic and parasympathetic divisions. Both divisions show antagonistic (opposite) effects on the organs that are innervated by them. The neuron that releases the neurotransmitter into the synapse is known as preganglionic neurons while the other that receives the neurotransmitter is called postganglionic neurons.
