Spinal column. Artwork of a frontal view of the human vertebral column. This column consists of blocks of bone called vertebrae, separated by intervertebral discs (blue-green). The spinal cord (not shown) runs down the space behind the vertebral bodies. Behind that are the vertebral processes, the bony protrusions to which back muscles and ligaments attach. There are 24 articulating vertebrae (cervical, thoracic and lumbar), extending from the base of the skull (top) to the pelvic region and the two fused structures of the sacrum and coccyx (bottom). Holes in the sacrum allow spinal nerves to branch out to the legs.
