The internal jugular vein is a paired jugular vein that collects blood from the brain and the superficial parts of the face and neck. This vein runs in the carotid sheath with the common carotid artery and vagus nerve. It begins in the posterior compartment of the jugular foramen, at the base of the skull.
The jugular veins are veins that take blood from the head back to the heart via the superior vena cava. The internal jugular vein descends next to the internal carotid artery and continues posteriorly to the sternocleidomastoid muscle.
The carotid sheath is a condensation of the deep cervical fascia [1]: 578 enveloping multiple vital neurovascular structures of the neck, [2] including the common and internal carotid arteries, the internal jugular vein, the vagus nerve (CN X), and ansa cervicalis. [1]: 578 [2] The carotid sheath helps protects the structures contained therein. [2]
Lateral to the artery, inside the carotid sheath with the common carotid, are the internal jugular vein and vagus nerve. At the lower part of the neck, on the right side of the body, the right recurrent laryngeal nerve crosses obliquely behind the artery; the right internal jugular vein diverges from the artery. On the left side, however, the ...
The right lymphatic duct courses along the medial border of the anterior scalene at the root of the neck. The right lymphatic duct forms various combinations with the right subclavian vein and right internal jugular vein.
internal jugular vein and its tributaries (correspondng to the branches of the corresponding artery): Superior thyroid vein, Lingual veins, Common facial vein (draining into the internal jugular vein) Ascending pharyngeal vein, Occipital vein (sometimes).

The small veins merge to feed as tributaries into medium-sized veins. The medium veins feed into the large veins which include the internal jugular, and renal veins, and the venae cavae that carry the blood directly into the heart. [13] The venae cavae enter the right atrium of the heart from above and below.
