The vagus nerve (cranial nerve X) carries most of the parasympathetic fibers in the body. It innervates various organs, including the heart, lungs, and digestive tract, helping to regulate functions such as heart rate, respiratory rate, and gastrointestinal activity. The vagus nerve plays a crucial role in the body's rest-and-digest response, promoting relaxation and energy conservation.

Are most innervated blood vessels receive only sympathetic nerve fibers?
No, most blood vessels are innervated by both sympathetic and parasympathetic nerve fibers. However, sympathetic nerve fibers typically have a more pronounced effect on blood vessel activity compared to parasympathetic fibers.
Is the vagus nerve sympathetic or parasympathetic?
The vagus nerve is parasympathetic.
The greater petrosal nerve is a branch of what cranial nerve?
The greater petrosal nerve is a branch of the facial nerve (cranial nerve VII). It carries parasympathetic fibers that innervate the lacrimal gland and nasal mucosa.
