The anterior jugular vein varies considerably in size, bearing usually an inverse proportion to the external jugular. [1] Most frequently, there are two anterior jugulars, a right and left. [1] [4] However, there is sometimes only one. [1] A duplicate anterior jugular vein may be present on one side, which may cross over the midline.
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 jugular vein has tributaries consisting of petrosal sinus, facial, lingual ...
Just above the sternum the two anterior jugular veins communicate by a transverse trunk, the jugular venous arch (or venous jugular arch), which receive tributaries from the inferior thyroid veins; each also communicates with the internal jugular. There are no valves in this vein.
It contains one or two lymph glands, the submental lymph nodes (three or four in number) and Submental veins and commencement of anterior jugular veins. (The contents of the triangle actually lie in the superficial fascia over the roof of submental triangle)

The external jugular vein can usually be seen through the skin; it runs in a line drawn from the angle of the jaw to the middle of the clavicle, and close to it are some small lymphatic glands. The anterior jugular vein is smaller and runs down about half an inch from the middle line of the neck. The clavicle or collarbone forms the lower limit ...
The facial vein usually unites with the anterior branch of the retromandibular vein to form the common facial vein, which crosses the external carotid artery and enters the internal jugular vein at a variable point below the hyoid bone.
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.
