Types of Spine

The spine, also known as the vertebrae or backbone is the structure which encloses and defends the spinal cord, and is the package of nerve fibers that sends signals from brain to whole body. It includes a collection of bone fragments around 33 vertebrae, the sacrum, and the coccyx and the intervertebral disks splitting the bone fragments. The spine is divided into areas known as the cervical, thoracic, and lower back, with the pelvic area containing the sacrum and coccyx, each considered as an individual entity.

Cervical spine is the most versatile anatomic area in the axial bones.  Segments of the cervical spine give us the ability to perform complicated throat actions like head switching and to carry weight or process the effect while defending the sensitive vertebrae and nerve roots origins that successfully go through the cervical vertebra. Vital components of the cervical spine, such as the disks, aspect joint parts, and around structures, are subject to recurring injury and degeneration from normal actions, such as work or sports, and from ageing, stress.
·      Thoracic spine represents the upper and middle-back. It joins the cervical spine at the end of the returning of the neck and expands down about five inches past the end of the shoulder muscles, where it joins with the lower back backbone.
·        Lumbar spine represents the back, where the spine curves inward towards the stomach. It starts about five to six inches wide below the neck muscles, and joins with the thoracic backbone at the top and expands downwards to the sacral spine.
·    Spinal degenerative disease represents any illness of the spinal that results from the ageing and damage that happens to the bone and soft cells of the spine. People who put increased stress on their neck and backs can increase the rate at which this damage happens. Some of them are:
  • Herniated disk is an outcropping of a disk that happens between each vetebral cuboid of the spine.
  • Spinal stenosis is the reduction of the spinal canal, due to narrowing of the spinal canals.
