Vertebrae Anatomy

Overview
The vertebral column or spine consists of 7 cervical vertebrae, 12 thoracic vertebrae, 5 lumbar vertebrae, the sacrum and the coccyx.  Each individual vertebrae shares some uniform structural characteristics, although each type has specific features relevant to its location and purpose in the spine.  Each vertebra has a body in the front that connects to the vertebral arch, which then creates the space in which the spinal cord travels through.  From the vertebral arch there is the spinous process, a tail of bone projecting along the center line of the spine, as well as the transverse processes which extend out from either side of the vertebral arch.  Both the spinous and transverse processes act as levers during movement.  Please note the only exception is the C1 vertebrae, also known as the “atlas”, which does not have a body or spinous process.
