The neck is a complex part of the human anatomy. In addition to supporting the head, it serves as a conduit of blood flow and nerve impulses between the brain and the rest of the body. In spite of this essential function, it’s highly vulnerable to injury, particularly the carotid and vertebral arteries. The carotid artery is close to the surface of the neck and can be injured by blunt trauma. Both the carotid and vertebral arteries can be injured by rapid or violent motions of the neck or when.
