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 operation encompasses removal of all the lymph nodes on one side of the neck, and includes removal of the spinal accessory nerve (SAN), internal jugular vein (IJV) and sternocleidomastoid muscle (SCM). 1957 – Hayes Martin describes routine use of the radical neck dissection for control of neck metastases.
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]
The jugular venous pressure (JVP, sometimes referred to as jugular venous pulse) is the indirectly observed pressure over the venous system via visualization of the internal jugular vein. It can be useful in the differentiation of different forms of heart and lung disease .
In over 95% of individuals, the thoracic duct ends by draining either at the venous angle, or into the internal jugular vein, or the subclavian vein, but - in the minority of cases - empties into either the brachiocephalic vein, external jugular vein, suprascapular vein, transverse cervical vein, or vertebral vein.

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 ...
It receives blood from the external palatine vein before it either joins the anterior branch of the retromandibular vein to form the common facial vein, or drains directly into the internal jugular vein. There are valves in the facial vein. [1] Its walls are not so flaccid as most superficial veins.
