Later, as the baby begins to sit up, and later pulls up on the coffee table, the spine changes again. We develop a lumbar curvature in the low back that—like the cervical curvature—is posteriorly concave. So, the adult spine has a slight S shape when viewed from the side.
WebThis diagram shows the curvatures associated with the different regions of the human vertebral column. The primary vertebral curve (concave forwards) is retained in the thoracic and sacral regions. The secondary curvatures in the cervical and lumbar regions are convex anteriorly.
