More specifically, the individual bones that form the spine are called vertebrae and link to each other at facet joints. The facet joints control the amount and direction of movement. Discs are located between the vertebrae and serve as shock absorbers and enhance flexibility. They are made up of a jelly-like center and tough bands surround that attach to the adjacent vertebrae. Ligaments are tough, non-elastic bands taht hold the bones together and muscles contract to provide additional support and movement.
Nerves allow control and provide sensation or feeling for our bodies.
Almost all back problems stem from improper body mechanics, poor posture, stressful work or life habits, decreased strength and flexibility, or general physical fitness decline. Injury prevention or treatment of a current back pain can make more sense if you understand the cause or source of the problem. Copyright Pella Regional Health Center 1998-2001. All rights reserved.
