Vagus nerve – dissection

Upon leaving the medulla oblongata between the olive and the inferior cerebellar peduncle, the vagus nerve extends through the jugular foramen, then passes into the carotid sheath between the internal carotid artery and the internal jugular vein down to the neck, chest, and abdomen, where it contributes to the innervation of the viscera, reaching all the way to the colon.

- Vagus nerve

Higher up, it is separated from the external carotid by the styloglossus and stylopharyngeus muscles, the tip of the styloid process and the stylohyoid ligament, the glossopharyngeal nerve and the pharyngeal branch of the vagus nerve.

This vein runs in the carotid sheath with the common carotid artery and vagus nerve.

It runs down the side of the neck in a vertical direction, being at one end lateral to the internal carotid artery, and then lateral to the common carotid artery, and at the root of the neck, it unites with the subclavian vein to form the brachiocephalic vein (innominate vein); a little above its termination is a second dilation, the inferior bulb.

The common carotid artery arises directly from the aorta on the left and as a branch of the brachiocephalic trunk on the right.

In anatomy, the left and right common carotid arteries (carotids) are arteries that supply the head and neck with oxygenated blood; they divide in the neck to form the external and internal carotid arteries.

To its right side below is the brachiocephalic trunk, and above, the trachea, the inferior thyroid veins, and the remains of the thymus; to its left side are the left vagus and phrenic nerves, left pleura, and lung.

Vascular compartment is paired and consists of the two carotid sheaths found on each side of the trachea. Each carotid sheath contains the vagus nerve, common carotid artery and internal jugular vein.

Arteries which supply the neck are common carotid arteries which bifurcate into the internal carotid artery and the external carotid artery.

The superior laryngeal nerve is a branch of the vagus nerve.

The superior laryngeal nerve descends, by the side of the pharynx, behind the internal carotid artery, and divides into two branches —the external laryngeal nerve and the internal laryngeal nerve.
