The vertebrae support the body and provide the protective bony corridor ( the spinal or vertebral canal) through which the spinal cord passes. The superior articular surfaces are directed upward and backward; the spinous process is thick, long, and almost horizontal. The vertebral column, also known as the backbone or spine, is part of the axial skeleton. The basic configuration of a vertebra varies; the large part is the body, and the central part is the centrum. Auditory foramen, internal the passage for the auditory ( vestibulocochlear) and facial.

Vertebra osteochondrozei vertebrale. The cervical spine ( the neck) has seven vertebral bodies, also called segments. The vertebral column is the defining characteristic of a vertebrate in which the notochord ( a flexible rod of uniform composition) found in all chordates has been replaced by a segmented series of bone: vertebrae separated by intervertebral discs. The transverse processes are long, and the upper vertebral notches are deeper than those of the other thoracic vertebrae.
