The neck, also called the cervical spine, is a well-engineered structure of bones, nerves, muscles, ligaments, and tendons. The cervical spine is delicate housing the spinal cord that sends messages from the brain to control all aspects of the body while also remarkably strong and flexible, allowing the neck to move in all directions. The neck is connected to the upper back through a series of seven vertebral segments. The cervical spine has 7 stacked bones called vertebrae, labelled C1 through C7. The top of the cervical spine connects to the skull, and the bottom connects to the upper back at about shoulder level.
