Cervical. The first seven vertebrae, all in the neck. These are smaller and lightly built. Thoracic. Twelve vertebrae, each articulating with the twelve pairs of ribs. Lumbar. The lower five vertebrae, between the ribs and the sacrum.These have the largest vertebral bodies. Each of the three segments of the spine has a curve. The cervical spine and the lumbar curve both are convex anteriorly, while the thoracic spine curves the opposite way, convex posteriorly.Each vertebra is shaped a bit like a wedge to support these curves, especially noticeable with the five lumbar vertebrae.he first seven vertebrae, all in the neck.
