The carotid sheath is a deep neck compartment that houses the main vascular and neural structures traveling to and from the head. Within this sheath you find the common carotid artery, the internal jugular vein, and the vagus nerve. The facial nerve does not run inside this sheath; it travels in the face and parotid region. The external jugular vein sits outside the sheath, superficial to it. So the three structures typically enclosed together in the carotid sheath are the common carotid artery, the internal jugular vein, and the vagus nerve.
