In humans, there are twelve thoracic vertebrae and they are intermediate in size between the cervical and lumbar vertebrae; they increase in size going towards the lumbar vertebrae, with the lower ones being a lot larger than the upper.
Fig. 1: Sagittal view of the cervical spine. (larger view). The cervical spine is comprised of seven vertebrae-C1, C2, C3, C4, C5, C6, C7 (often noted as C1-C7) - that begin at the base of the skull and extend down to the thoracic spine.he first cervical vertebra is unique in that it is a ring that rotates around the second vertebral body (the odontoid). The cervical vertebrae closest to the skull are the smallest. All of the cervical vertebrae are smaller than the vertebrae in the thoracic spine (upper back) and the lumbar spine (lower back).
