Lumbar spine anatomy

16.04.2019

The lumbar spine (low back) is the third major region of the spine; it is below the cervical spine and thoracic spine (Figure 1). Most people have five bones (vertebrae) in the lumbar spine, although it is not unusual to have six. Each vertebra is stacked on top of the other and between each vertebra is a gel-like cushion called an intervertebral disc. The discs help to absorb pressure, distribute stress, and keep the vertebrae from grinding against each other.

"If you would seek health, look first to the spine." -Socrates

The spine is one of the most important parts of the body. It provides structure and support, and without it, you would not be able to stand up, let alone keep yourself upright.
