The Lumbar Spine consist of 5 vertebrae numbered L1 - L5. Each Vertebrae is stacked on top of the other between each vertebrae is a gel like cushion called intervertebral disc. The disc helps to absorb pressure, distribute stress and keep the vertebrae from damaging. The vertebrate and disc are held together by group of ligaments. The ligaments and tendons helps to stabilize the spine and guard against excessive movements in any one direction. The spine also had joints like knees, elbows and other joints. The spinal joints are called Facet joints. The Facet joints helps to make the spine flexible and enable you to bend forward, backward side to side. The lumbar spine is designed to be incredibly strong, protective, the highly sensitive spinal cord and spinal nerve roots. At the same time it is highly flexible , providing mobility in many different planes including flexion, extension, side bending and rotation.
