What parts of the typical vertebra are included in the anterior portion of the vertebra? In the posterior portion?
What will be an ideal response?
ANS: The anterior portion of the typical vertebra is composed of the vertebral body. The body has
growth epiphyses (in the skeletally immature person) around the periphery of the superior and
inferior vertebral plateaus, with a cartilaginous end plate in the center. The intervertebral disc is
interposed between the bodies of most vertebrae. The posterior portion of the vertebral body is
composed of the vertebral arch. The arch is formed by the pedicles anteriorly (which are
sometimes considered part of the anterior vertebra) and the laminae posteriorly. The laminae begin
posterior to the transverse processes and join to form the spinous process of the vertebra. The
superior and inferior facets are part of the posterior portion of the vertebral arch.
