The coccyx and sacrum are fused together and allow no movement at all.
Describe the lumbar vertebrae?
The lumbar is the largest vertebrae as it absorbs most amount of shock throughout the spine.
Allows limited rotation, lateral flexion and extension.
Describe the thoracic vertebrae?
Lower thoracic allows rotation, lateral flexion and extension. The upper thoracic is limited to flexion and extension.
