The carotid artery, internal jugular vein and vagus nerve are enwrapped by the loose areolar carotid sheath. The sheath is related to the prevertebral fascia posteriorly and to the visceral fascia medially. It provides a good plane of dissection to mobilize the vessels.

The majority of the carotid sheath is covered by the sternocleidomastoid muscle. The external jugular vein passes across the outer surface of the muscle communicating with the deeper veins above and below.
