First, I would like to say a few words on the spine! The spineor also called the backbone or spine consists of a series of bones called vertebrae stacked one on another. There are four regions of the spine: cervical (neck); thoracic (chest / trunk); lumbar (lower back) and sacral (pelvis). You should also know that the cervical spine is composed of seven cervical vertebrae. The main function of the cervical spine is to support the weight of the head is about 10 to 12 pounds. The cervical spine has the greatest range of motion, in part because of two specialized vertebrae that move with the skull.
cervical vertebrae are the smallest of the vertebrae. The first cervical vertebra is called the atlas and is significantly different from the other vertebrae. It is similar to a ring-shaped with two large bulges on the sides to support the weight of the head. The second cervical vertebra is called the axis. The shaft is also unique because it has a PEG-like bony protrusion, called the dens or odontoid on its upper surface that fits within the ring of the atlas. The curve of the neck is described as a lordosis curve, and looks like a “C” in reverse.
The main function of the thoracic spine is to protect the chest organs, especially the heart and lungs. There are 12 thoracic vertebrae with a rib attached on each side to create a rib cage that protects the internal organs of the chest. The thoracic spine has a normal kyphosis or curve “C”. The thoracic spine is less mobile than the cervical and lumbar spine due to the rib cage. And finally – the lumbar spine has five lumbar vertebrae, which are most vertebrae. These vertebrae are also aligned in a reverse “C” as the cervical spine, creating a normal lumbar lordosis. The five lumbar vertebrae are the portion of weight-bearing spine and are larger in diameter compared to the thoracic spine and cervical vertebral bodies
