The cranial nerve that allows communication between the stomach and brain is called the ______________ nerve.

Explanation:
The main idea is that gut–brain communication is largely carried by the vagus nerve, the tenth cranial nerve. It provides the primary parasympathetic link between the brain and the stomach, sending sensory information about stomach distension and contents up to the brain and carrying motor signals from the brain to promote digestion. This bidirectional pathway explains how fullness, hunger, and digestive activity are coordinated. The optic nerve is involved in vision, the trigeminal nerve in facial sensation and chewing, and the hypoglossal nerve in tongue movement.
