Document Summary
The veins of the head and neck collect deoxygenated blood and return it to the heart. Anatomically, the venous drainage can be divided into three parts: Venous drainage of the brain and meninges: supplied by the dural venous sinuses. Venous drainage of the scalp and face: drained by veins synonymous with the arteries of the face and scalp. These empty into the internal and external jugular veins. Venous drainage of the neck: carried out by the anterior jugular veins. In this article, we shall look at the veins mentioned above, their anatomical course, and any clinical correlations. There are three main jugular veins external, internal and anterior. They are ultimately responsible for the venous drainage of the whole head and neck. The external jugular vein and its tributaries supply the majority of the external face. It is formed by the union of two veins: Posterior auricular vein drains the area of scalp superior and posterior to the outer ear.
