The cervical section is very flexible, allowing Flexion, Extension, Lateral Bending and Rotation. 50% of flexion and extension is at the Atlanto-occipital joint and 50% of rotation is at the Atlanto-axial joint.
The thoracic section is primarily responsible for Rotation. Lateral Bending, Flexion and Extension are very limited because of the vertebral structure. For example notice how the spinous processes of the thoracic vertebrae point down, locking together in a fish scale pattern to prevent extension.
The Lumbar section has the largest and strongest vertebrae of the spine since it holds all the weight of the upper body. It’s also very flexible, allowing Flexion, Extension and Lateral Bending. However it is limited in its ability to Rotate.
Combined together, the three sections allow the spine to be incredibly flexible, with significant Flexion, Extension and Lateral Bending, as well as being able to Rotate nearly 180 degrees.
