Sep 23, 2023 · The vagus nerve, also known as the tenth cranial nerve (CN X), is one of the most complex and multifunctional nerves in the body. It is primarily a mixed nerve, meaning it contains both motor and sensory fibers, and has a significant role in the autonomic nervous system.

The pharyngeal branches arise from the inferior ganglion of the vagus nerve and contain visceral afferent fibers and motor fibers. The motor efferent fibers are supplied by the accessory nerve (CN XI) which joins the pharyngeal nerve. The pharyngeal branch of the vagus nerve passes across the internal carotid artery to the middle pharyngeal constri...
It is a structure of IV branchial arch and thus innervates the pharyngeal and laryngeal derivatives of this arch. The afferent fibers of the superior laryngeal nerve arise from the inferior ganglion of the vagus nerve. This branch receives some sympathetic fibers from the superior cervical ganglion. At the level crossing of the hypoglossal nerve (C...
Also known as the inferior laryngeal nerves, there are two recurrent laryngeal nerves, one on the right side of the body and one on the left. They were appropriately given the name recurrent laryngeal nerves as they follow a recurrent course and travel in the opposite direction to the nerve they branched from. The recurrent laryngeal nerve contains...
The superior cardiac nerve branches off the vagus nerve at the upper (superior) and lower (inferior) parts of the neck. Therefore, there are two branches of the superior cardiac nerve on each side. The left superior branch descends lateral to the trachea, in front of the esophagus and deep to the aortic arch and merges with the deep part of the car...
1 day ago · The vagus nerve provides parasympathetic innervation to the majority of the abdominal organs. It sends branches to the oesophagus, stomach and most of the intestinal tract – up to the splenic flexure of the large colon.
