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 left and right external jugular veins drain into the subclavian veins. The internal jugular veins join with the subclavian veins more medially to form the brachiocephalic veins. Finally, the left and right brachiocephalic veins join to form the superior vena cava, which delivers deoxygenated blood to the right atrium of the heart. [2] The ...
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]
On the left side, however, the left internal jugular vein approaches and often overlaps the lower part of the artery. Behind the angle of bifurcation of the common carotid artery is a reddish-brown oval body known as the carotid body. It is similar in structure to the coccygeal body which is situated on the median sacral artery. The relations ...
The left brachiocephalic vein is about 6cm, more than twice the length of the right brachiocephalic vein. [3] and is formed by the confluence of the left subclavian and left internal jugular veins. In addition the left vein receives drainage from the following tributaries:
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 first sign of a malignancy, especially an intra-abdominal one, may be an enlarged Virchow's node, a lymph node in the left supraclavicular area, in the vicinity where the thoracic duct empties into the left brachiocephalic vein, right between where the left subclavian vein and left internal jugular join (i.e., the left Pirogoff angle).
Each inferior petrosal sinus drains the cavernous sinus into the internal jugular vein. ... in the public domain from page 659 of the 20th edition of Gray's Anatomy ...
