VERTEBRAL COLUMN

vertebral column

The portion of the axial skeleton consisting of vertebrae (7 cervical, 12 thoracic, 5 lumbar, the sacrum, and the coccyx) joined together by intervertebral disks and fibrous tissue. It forms the main supporting axis of the body, encloses and protects the spinal cord, and attaches the appendicular skeleton and muscles for moving the various body parts.
Synonym: spinal column See: illustration

vertebral column

The bony spine. A curved column of bones, called vertebrae, of the same general shape but increasing progressively in size from the top of the column to the bottom. Each vertebra has a stout, roughly circular body behind which is an arch that encloses an opening to accommodate the spinal cord. The arch bears bony protuberances on either side and at the back and facets for articulation with the vertebrae above and below. The vertebral bodies are fixed together by cushioning intervertebral discs and strong longitudinal ligaments. There are 7 neck vertebrae, 12 in the back and 5 in the lumbar region. The 5th lumbar vertebra sits on top of the sacrum, which is formed from the fusion of five vertebrae. The coccyx, hanging from the lower tip of the sacrum, is the fused remnant of the tail.

Vertebral column

The vertebral column, also called the spinal column or spine, consists of a series of vertebrae connected by ligaments. It provides a supporting axis for the body and protects the spinal cord. The vertebral column consists of seven cervical vertebrae in the neck, followed by 12 thoracic vertebrae that connect to the ribs, five lumbar vertebrae in the lower back, the sacrum, and the coccyx.

Patient discussion about vertebral column

Q. Anyone have knowledge of cancer in the spine? Doctors think my 40 year old brother has. My brother has been undergoing test and treatnment for back problems since a vehicle accident in August. The did a test last week and Monday said they saw 4 nodules they think are cancer, his doctor said everytime he had seen this it was cancer. I am devestated right now but trying to stay positive. I am sure you will notice it on the site b/c I know it is affecting me and the stress and worry has the fibromyalgia kicking in at full speed:-( PLEASE anything you can tell me would be a help!

A. Thank you for the answer and the prayers!

Q. I have hurt my cervical spine and shoulder in a rear end car crash in July. Why does it still hurt?

A. Spine and back injuries are known to to be causing a lot of pain and discomfort and for a long period of time. You should try and do some mellow exercise and physiotherapy that might help you a lot. If the pain is unbarable, you should consult your doctor about using pain medications.

Q. Has anyone had a spine fusion that failed? Or hardware that failed?

A. Haven't experienced it myself, but here (http://www.spine-health.com/forum/treatments/back-surgery-and-neck-surgery) you may find a discussion about it.
