How many cervical vertebrae are there in the human body?

The human body contains a total of seven cervical vertebrae, which are identified as C1 through C7. These vertebrae are located in the neck region and play a crucial role in supporting the skull, providing mobility and flexibility to the head and neck, and protecting the spinal cord as it passes through the vertebral foramen of each vertebra. The structure of the cervical vertebrae allows for a wide range of motion, enabling activities such as nodding and rotation of the head. Understanding the number and function of these vertebrae is important for both anatomical knowledge and for health professionals involved in diagnosing and treating spinal conditions.
