Vein Jugular External

The external jugular vein, also known as the descending pharyngeal vein and angular thoracic vein, is one of four major veins that drain blood from the head and neck. It runs along the side of the neck, crossing the collarbone and chest, and drains into the left innominate vein.

The jugular vein originates from the jugular vein in the neck, which connects to the superior jugular duct. It then passes through the sternocleidomastoid muscle upward and to the left, where it divides into a posterior group and an anterior group.

The posterior group of internal veins flows along the back of the neck and passes into the base of the skull. This group includes the occipital vein and one of the two paramedian veins. The anterior group passes under the anterior surface of the neck and drains into the internal jugular vein at the angle of the mandible.

The vein is the most important structure when it comes to transporting oxygen and nutrients from the neck to the brain and the rest of the body.
