Which section of the vertebral column contains 7 cranial vertebrae?

• A. Cervical
• B. Thoracic
• C. Lumbar
• D. Sacral

Answer: (A)

The section of the vertebral column that contains 7 cranial vertebrae is the cervical region. This area is located at the top of the vertebral column and consists of seven vertebrae, labeled C1 through C7. The cervical vertebrae are unique due to their smaller size and the presence of specific features, such as transverse foramina, which allow for the passage of the vertebral arteries and veins. This region supports the head, facilitates a wide range of motion (such as rotation, flexion, and extension), and provides the necessary structural support for the skull. The first two cervical vertebrae, known as the atlas and axis, allow for the nodding and rotating movements of the head, respectively. Understanding the composition and function of the cervical vertebrae is crucial for studying the overall anatomy of the spine and its role in the nervous system and musculoskeletal functions.
