Your spine is a complex structure, made up of 33 individual bones (known as vertebra) stacked one on top of each other. These are supported and connected together by ligaments and muscles, giving them the stability and flexibility it needs to function and move.
The lumbar spine typically has a slight inward curve known as lordosis. The lower back region contains large muscles that support the back and allow for movement in the trunk of the body. These muscles can spasm or become strained, which is a common cause of lower back pain.
Stretching down the midline of the trunk from the base of the skull to the coccyx, the spine plays an extremely important role in our bodies as it supports the upper body’s weight; provides posture while allowing for movement and flexibility; and protects the spinal cord.This diagram with labels depicts and explains the details of Picture Of The Spine.
