What is the cervical section of the vertebral column composed of?

The cervical section of the vertebral column is composed of 7 vertebrae, commonly referred to as C1 through C7. These vertebrae are specifically structured to provide flexibility and support to the neck while protecting the spinal cord. Each cervical vertebra has unique characteristics, such as smaller bodies compared to other vertebrae and the presence of transverse foramen, which facilitate the passage of important blood vessels and nerves.

Having seven cervical vertebrae is crucial for distinguishing this section from other areas of the spine, such as the thoracic section, which has 12 vertebrae, and the lumbar section, which has 5. This anatomical knowledge is essential for fitness instructors, as an understanding of the vertebral column aids in safely designing exercises and understanding the implications of spinal alignment on overall movement and health.
