Major Regions of the Back
Cervical spine (neck)
The cervical spine begins at the base of the skull. It consists of seven vertebrae and eight pairs of cervical nerves.
Cervical pain can result from a slipped disc, osteoporosis, scoliosis and, in rare cases, structural damage due to tumors or infection. Trauma or injury, such as whiplash, can cause neck pain that takes months to improve.
Thoracic spine
The thoracic spine is the long middle portion of the back and the longest portion of the spinal column. It consists of 12 vertebrae. The ribs of the chest connect to the thoracic spine, protecting vital organs in the torso.
Thoracic pain is often caused by fractures, especially in athletes and the elderly, osteoporosis, automobile accidents, falls or other trauma.
Lumbar spine
The lumbar spine, or low back, includes the five largest and strongest vertebrae. Between each vertebra is a gel-like disc that helps absorb pressure, distribute stress and keep the vertebrae from grinding against each other.
The low back is vulnerable to many pain-provoking disorders, ranging from simple strains to a herniated disc, degenerative disc disease, spondylolisthesis or spinal stenosis.
