How does the parasympathetic nervous system affect the eyes?

Via multineuronal pathways, it activates specific parasympathetic pathways arising from the ciliary ganglion. This pathway causes the ciliary muscle to contract, thereby reducing tension on the lens and allowing it to become more rounded so the image of the near object can be focused on the central part of the retina.

Is skin part of the nervous system?
