Anatomy of the Spine


Transcript

The spine consists of a series of interconnected bones, called vertebrae, extending from the base of the skull to the tailbone.

Each vertebra connects with the one above and below at the facet joints, allowing them to move relative to one another.

In between each bony vertebra lies a shock-absorbing intervertebral disc.

The facet joints and intervertebral discs work together to permit the bending and twisting motions of the back and neck.

Protected within the vertebral column is the spinal cord, which connects the brain to the rest of the body.

Spinal nerves emanate from the spinal cord at regular intervals.
