What Does the Backbone Do?

The vertebral column, most commonly known as the backbone, though also referred to as the spine or simply spine, is made up of the several bones called vertebrae. There are doughnut or disc shaped bones, called inter vertebral discs, that have a lot of cartilage in their structure along with a jelly-like substance in the middle. The curious design is so that these disc may be able to offer maximum shock and impact protection. The vertebral column contributes to or performs important functions in the human body. Some of these functions are movement, protection of vital nerves and organs, structure and support.

The vertebral column is the most important component in keeping human upright. Several other muscles and ligaments aid te vertebral column but main weight bearing component is still the vertebral column. Above the vertebral column is connected to the shoulders and below it is connected to the pelvic girdle.

The first two vertebrae of the vertebral column work together, forming a pivot joint, to allow the human head to rotate giving human the ability to “look around” without the need move the rest of their bodies while executing the act. These top two bones are called atlas and axis.

The spinal cord, a portion of the central nervous system, is protected by the vertebral column. This is one of the most import function of the vertebral column after that of hold the human body upright. Another function of the vertebral column is the protection of vital internal organs. The spine contributes to this role by serving as an anchoring point for each of the ribs that form the rib cage.
