Low Back Health Series Part 2: Lower Back Anatomy 101

Basic anatomy of the lower back or lumbar spine.

Your lower back is the area between your lowest rib and the upper part of the buttock. Your spine in this region has a natural inward curve. This curve is called Lordosis and it actually serves several purposes.

Firstly, the spine supports the weight of the upper body. It also aids in reducing the concentration of stress in the area.

The lower back has 3 major contributors. Vertebrae, discs, and facet joints. Your lumbar vertebrae are labelled L1 to L5 which increase in size allowing them to bear more weight.

Your discs sit in between your vertebrae, the discs provide cushioning & help with shock absorption.

Finally, the facet joints are connected to the spine. They provide stability and also allow movement in different directions. The joints are lined with cartilage which allows for smooth movement.

There are several nerves that run along the lumbar of the spine.

Your L1 spinal nerve provides sensation to your groin and genital regions and may contribute to the movement of your hip muscles.

Your L2, L3, and L4 spinal nerves provide sensation to the front part of your thigh and along the inner side of your lower leg. These nerves also control movements of your hip and knee muscles.

Your L5 spinal nerve provides sensation to the outer side of your lower leg, the upper part of your foot, and the web-space between your first and second toes.

The L4 and L5 nerves (along with other nerves) contribute to the formation of the largest nerve in your body, the sciatic nerve, which runs down from your rear pelvis, into the back of your leg, and terminates in your foot.
