How many cervical vertebrae are there in the human spine?

The human spine consists of seven cervical vertebrae, which are designated as C1 through C7. These vertebrae are located in the neck region and are crucial for supporting the skull, allowing for a range of head movements, and providing protection for the spinal cord as it runs down through the vertebral column. Each cervical vertebra has a unique structure that accommodates the attachment of muscles and ligaments while facilitating motion.

The cervical spine plays a vital role in maintaining the overall balance and flexibility of the spine, contributing to the functional anatomy of the upper body. Understanding the number and function of these vertebrae is essential for anyone entering the medical field, as it relates to both anatomy and the assessment of potential spinal injuries.
