Which cranial nerves are associated with parasympathetic reflexes of the stomach?

The correct answer pertains to the cranial nerves that play a crucial role in the parasympathetic innervation of the stomach. The vagus nerve, also known as cranial nerve X, is primarily responsible for supplying parasympathetic fibers to the gastrointestinal tract, including the stomach. It facilitates various digestive functions such as increasing motility and stimulating digestive secretions.

The accessory nerve is not primarily involved in parasympathetic functions; it mainly regulates muscle movement. While the glossopharyngeal nerve (cranial nerve IX) does have some parasympathetic roles, particularly in salivary glands, it does not innervate the stomach directly like the vagus does.

Understanding the role of these cranial nerves within the autonomic nervous system provides insight into how the body regulates internal processes such as digestion. Hence, the vagus nerve is the primary player in mediating parasympathetic reflexes related to the stomach, making the other answers less relevant in this context.
