===The human spine is arguably one of the most important structures in the entire human body! It is aslo one of the most complex. In human anatomy the spine (also known as the backbone or vertebral column) houses and protects the spinal cord, which controls the nerves of the body. The spine consists of thirty-three vertebrae, a sacrum, intervertebral discs, and the coccyx. A Verta-What?!! These names can sound really intimidating, but they are actually quite easy to understand. Let's break it down.=== ===A vertebra is a single individual bone that makes up the entire spinal column. It has a very odd and irregular shape which allows for great strength and flexibility. There are usually 33 vertebra, including those that are fused to the base of the sacrum.=== . **The spine is divided into four sections: Cervical, Thoracic, Lumbar, and Pelvic (which consists of sacrum and coccyx). These sections make up your entire spine! Now that you have the basic understanding of the spinal structure, let's get more in d****epth.** Joints of the Spine Curves of the Spine Abnormalities of the Spine //__All pictures and photographs provided by flickr.com__//
 * The sacrum is a large triangler bone located at the base of the spine and the upper section of the pelvic cavity. It is wedged** **between the two hip bones and its bottom part connects with the coccyx.**
 * The coccyx ( or the tailbone ) is the bottom end segment of the entire spine. Its odd structure provides for muscle attachment and a great amount of support, especially if your'e sitting down!**
