The parasympathetic fibers of the nerves innervate smooth muscles of the eye that cause the lenses to bulge to accommodate close vision.

Solution:

The parasympathetic fibers of the nerves innervate smooth muscles of the eye that cause the lenses to bulge to accommodate close vision is oculomotor.

The oculomotor nerve is the third of 12 pairs of cranial nerves in the brain. This nerve is responsible for eyeball and eyelid movement. It follows the olfactory and optic nerves in terms of order.

Thus the required right answer is oculomotor.

Chemical digestion reduces large complex molecules to simpler compounds by the process of catabolism. Catabolism is the set of metabolic pathways that breaks down molecules into smaller units that are either oxidized to release energy, or used in other anabolic reactions.
