What is the total number of cervical vertebrae in the human body?

The human body contains a total of seven cervical vertebrae. These vertebrae are found in the neck region and are designated as C1 through C7. The first vertebra, C1, is known as the atlas, which supports the skull and allows for the extension and rotation of the head. The second vertebra, C2, is called the axis and enables the head to pivot.

The cervical vertebrae are crucial for providing flexibility and support to the neck while also protecting the spinal cord as it passes through the vertebral foramen. Each cervical vertebra has distinct characteristics, such as uniquely shaped transverse foramina that allow for the passage of blood vessels.

Understanding the correct number of cervical vertebrae is essential not only for anatomical studies but also for clinical applications in medicine and healthcare, as variations or injuries in this area can significantly impact a person's health and mobility.
