More Information
The glossopharyngeal nerve, also known as the 9th cranial nerve, is a mixed nerve that carries afferent sensory and efferent motor information. Its function in the salivary glands highlights the integration of nerve function and salivation, underscoring the complex interplay in autonomic control of the body's secretory systems.
Tips
A common mistake is confusing the glossopharyngeal nerve with the facial nerve, which innervates other salivary glands like the submandibular and sublingual glands.
