Which cranial nerve is known as the Vagus Nerve?

The Vagus Nerve is indeed the 10th cranial nerve, and it plays a critical role in the parasympathetic nervous system. Its name, "vagus," comes from the Latin word for "wandering," which reflects its extensive distribution throughout the body. The Vagus Nerve is responsible for a wide range of functions, including control of heart rate, gastrointestinal peristalsis, sweating, and many muscle movements in the voice box (larynx). Its broad effects on various organs make it essential for maintaining homeostasis in the body.

Understanding the functions of the Vagus Nerve is important in the context of dental anesthesia, as its influence on heart rate and bodily functions can affect patient management during procedures and anesthesia.
