What is vagal triangle?
What is vagal triangle?
Vagal triangle (Trigonum vagi or ala cineria), is a triangular dark area bounded laterally by the vestibular area, medially by the hypoglossal triangle and above by the inferior fovea. It overlies the nuclei of glossopharyngeal, vagus and cranial accessory nerves.
What does the dorsal motor nuclei do?
The dorsal vagal nucleus, also known as the vagal nucleus, dorsal nucleus of the vagus nerve or the dorsal motor nucleus of the vagus nerve, is a elongated nucleus within the medulla oblongata that provides parasympathetic motor innervation to the viscera of the thorax and abdomen.
Where is hypoglossal trigone located?
medulla oblongata
Anatomical terms of neuroanatomy In the upper part of the medulla oblongata, the hypoglossal nucleus approaches the rhomboid fossa, where it lies close to the middle line, under an eminence named the hypoglossal trigone.
Where is the dorsal nucleus of vagus?
dorsal medulla
The dorsal vagal nuclei are paired nuclei located in the medial aspect of the dorsal medulla either side of the midline. They are the most dorsal of the medullary nuclei, forming the vagal trigone in the floor of the fourth ventricle at its most rostral extent.
What side is vagus nerve on?
Although we refer to the vagus nerve as singular, it’s actually a pair of nerves that emerge from the left and right side of the medulla oblongata portion of the brain stem.
Which other cranial nerve is also distributed to the tongue?

What is the path of the vagus nerve?
Course. The vagus nerve runs from the brain through the face and thorax to the abdomen. Exits the brain from the medulla oblongata of the brainstem and travels laterally exiting the skull through the jugular foramen.

- Probiotics.
- Meditation.
- Omega-3 Fatty Acids.

Where is the trigone located in the vagus nerve?
