Apr 26, 2021 · Vagus nerve: topography, branches, innervation territories, fiber spectrum. The rootlets of the vagus exit the medulla oblongata in the retro- olivary sulcus together with the root of the glossopharyngeal nerve and the cranial root of the accessory nerve.
Nov 7, 2022 · The vagus nerve (cranial nerve [CN] X) is the longest in the body, containing both motor and sensory functions in afferent and efferent regards. The nerve travels widely throughout the body, affecting several organ systems and regions of the body, such as the tongue, pharynx, heart, and gastrointestinal 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...
The vagus nerve is an indispensable body-brain connection that controls vital aspects of autonomic physi-ology like breathing, heart rate, blood pressure, and gut motility, reflexes like coughing and swallowing, and survival behaviors like feeding, drinking, and sickness responses.
Vagus Nerve (X) 391 Apparent Origin of Vagus Nerve, Posterolateral Sulcus of Medulla Oblongata Anatomy The vagus nerve (X) is composed of parasympathetic, sensory and motor fibers. It arises via six to eight rootlets from the pos terolateral sulcus of the medulla oblongata (Fig. 10.1 0; 11.6 a). Rootlets merge together, forming a single trunk.

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.

Jan 19, 2022 · Prescott and Liberles review sensory biology of the vagus nerve, a major arm of the interoceptive nervous system and vital body-brain relay. Vagal sensory neuron functions, anatomical projections, responses, and sensory receptors are discussed across physiological systems.
