Flashcards in Vagus nerve (dave's notes) Deck (9):
1

What general rule of thumb does the course of the vagus nerves follow?

They try to reach the midline and move posteriorly (c.f. phrenic)

2

What is the right vagus nerve in contact with?

The trachea

3

What holds the left vagus nerve away from the midline?

The great arteries. Crosses the aortic arch MEDIAL to the superior intercostal vein c.f. phrenic.

4

In the thoracic cavity, each vagus nerve passes down behind what? Supplies what at this point?

Behind each lung root, and give off a large supply to the pulmonary plexus.

5

After contributing to the pulmonary plexus, where do the vagus nerves pass?

To the oesophageal plexus where they mix in the midline.

6

What nerves are branches of the vagus?

The right and left recurrent laryngeal nerves

7

Where is the right recurrent laryngeal nerve given off?

At the neck root around the right subclavian artery

8

Where is the left recurrent laryngeal nerve given off?

?Given off by hooking around the left atrium, then ascends in the trachea-oesophageal groove
