Veins To The Head And Neck
Every story ever made about vampires have all educated people think about the existence of the external jugular veins. They are the veins used to drain some part of the facial area, the superficial neck regions and the scalp. They are situated near the sternocleidomastoid muscles and they connect with the platysma muscle. Following that same path, they run into the right and left subclavian veins which are found immediately below the clavicle.
The internal jugular veins are instrumental in the venous drainage of the brain and the meninges. The neck and the more internally-located regions of the face are affected, too. The internal jugular veins are more exposed to the internal body, and they are bigger compared to external jugular veins. Located between the dura mater layers, they are placed near the cranial venous sinuses. These venous sinuses facilitate the reception of the blood coming from the opthalmic, cerebellar and meningeal veins. The internal jugular veins run down the vagus nerve and the common carotid artery, situated near the inferior regions of the neck.
The carotid sheath protects all the veins located beneath the sternocleidomastoid muscles . The brachiocephalic vein is formed by the connection of the subclavian veins and the internal jugular veins. This is true for both sides of the body. The two brachiocephalic veins combine to join the superior vena cava and the blood gets deposited into the right atrium.
