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 , pharylingual, the thyroid , and sometimes the occipital vein .
The jugular veins are relatively superficial and not protected by tissues such as bone or cartilage.This makes them susceptible to damage. Due to the large volumes of blood that flow through the jugular veins, damage to the jugulars can quickly cause significant blood loss, which can lead to hypovolæmic shock and then death if not treated.
The external jugular vein receives the greater part of the blood from the exterior of the cranium and the deep parts of the face, being formed by the junction of the posterior division of the retromandibular vein with the posterior auricular vein.
vena jugularis anterior [1] TA98: A12.3.05.047: TA2: 4959: FMA: 13318: Anatomical terminology [edit on Wikidata] The anterior jugular vein is a vein in the neck ...
The posterior external jugular vein begins in the occipital region and returns the blood from the skin and superficial muscles in the upper and back part of the neck, lying between the splenius and trapezius.
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.
The term "hepatojugular reflux" was previously used as it was thought that compression of the liver resulted in "reflux" of blood out of the hepatic sinusoids into the inferior vena cava, thereby elevating right atrial pressure and visualized as jugular venous distention. The exact physiologic mechanism of jugular venous distention with a ...
Yellow circle indicates the left venous angle. The venous angle (also known as Pirogoff's angle and in Latin as angulus venosus) is the junction where the ipsilateral internal jugular vein and subclavian vein unite to form the ipsilateral brachiocephalic vein.
