The cervical spine is the upper part of the spine, located in the neck. It consists of seven small bones called vertebrae, labeled C1 to C7. These vertebrae support the head, allow for neck movement, and protect the spinal cord, which is a vital part of the nervous system. Each cervical vertebra has a unique shape and function. For example, the first vertebra, known as C1 or the atlas, supports the skull and allows for nodding. The second vertebra, C2 or the axis, enables the head to rotate. Together, they play a crucial role in our ability to move and maintain balance.
