Final answer:
The parasympathetic component of CN III is located peripherally.
Step-by-step explanation:
The parasympathetic component of CN III is located peripherally. The parasympathetic division of the autonomic nervous system has central neurons located in nuclei of the brain stem and the lateral horn of the sacral spinal cord. In the case of CN III, the preganglionic parasympathetic fibers terminate in the ciliary ganglion, which is located in the posterior orbit.
