Final answer:
The cervical spine is made up of seven vertebrae, which are the topmost part of the vertebral column that includes 24 vertebrae.
Step-by-step explanation:
The cervical spine is composed of seven vertebrae, which are designated as C1-C7. These are part of the vertebral column that in total consists of 24 vertebrae, plus the sacrum and coccyx. The cervical vertebrae are located in the neck and are the uppermost segment of the vertebral column. Of note, the vertebral column's primary curvatures include the thoracic and sacrococcygeal curves, which are present at birth, while the secondary curvatures, cervical and lumbar, develop later.
