The Scapula And Pelvis
The spine is the axis of the body that extends from the base of the skull to the pelvis and articulates two belts: the scapula and pelvis. And she must reconcile two mechanical constraints: rigidity-strength of the bone pieces, which are the vertebrae and flexibility, which in turn bring up the numerous pieces of bone and disks that are joined together by muscles and ligaments.
Two vertebrae, which are a motion segment, are linked through three joints: An earlier, formed by the vertebral bodies and intervertebral disc, two posterior. These make up the spinal joints. The intervertebral disc is composed of an annulus and a nucleus pulposus.
The annulus is composed primarily of collagen and the nucleus pulposus mainly of water. This structure is to absorb and withstand the pressures that are placed on the spine and is designed, specifically, to support different compression forces.
Whenever there is proper alignment, vertebral bodies can become fractured by compressive forces without any damage to the intervertebral disc. But before this we have to reflect what we do today to that before injuring the vertebral body is injured the disk itself? The answer is unanimous: the sedentary lifestyle. And, hypokinesia, with bad posture habits, accelerates the process of degeneration of this tissue.
