The main function of the spine is to hold the weight of the body and to provide stability in movement. There are thirty or more bones in the spine, and they are made up of many smaller bones and components such as ligaments, nerves and muscles. These parts work together in a complex manner, and are responsible for holding and carrying the spine in an upright and balanced position. The spine can become sore and damaged if we do not take care of it and do not sit on a proper Operator Chair, like the ones from Bestbuy Office Chairs, during the day. There are two types of spinal column:
The first part of the spine is called the cervical spine, and it consists of the upper vertebrae and the fifteen or so smaller lumbar vertebrae. The cervical spine carries the neck vertebrae and the numerous joints that make up the shoulders and arms. The cervical spines are not involved in movement and are enclosed within the rib cage.
The next section of the spine is called the thoracic spine, and it is composed of the fifteen or so large bones of the upper back and the numerous joints that make up the arms and shoulders. It is important to note that these spines also contain the ribs, which are important stabilizers of the upper body. The third section of the spine is called the ulnar spinal column, which consists of only the ten or so small bones of the arm.
