Final answer:
The vertebral column consists of seven cervical vertebrae in the cervical region, which support the head and neck and protect the spinal cord.
Step-by-step explanation:
The vertebral column, also known as the spine, includes several regions, each with a specific number of vertebrae. Specifically, in the cervical region of the vertebral column, there are seven cervical vertebrae (C1-C7). This region of the vertebral column provides support and mobility to the head and neck, and the cervical vertebrae also protect the spinal cord that runs through them. The primary curvatures of the vertebral column, which are present from birth, include the thoracic and sacrococcygeal curves, while the cervical region develops a secondary curvature as infants begin to lift their heads.
