Anatomy of the spine and spinal nerves

A simple description of the neck bone (cervical spine) and the hip bone (lumbar spine) is as follows.

 The block-shaped bone (vertebral body) and the cartilage (intervertebral disc) that serves as a cushion overlap to form a pillar. Behind it is a ring of bones (spinal canal), which contains a bundle of nerves (spinal cord). Two nerve branches (nerve roots) grow from the bundle of nerves on each side of each bone.

Neck bones (cervical spine) and nerves

The basic structure of the neck and hips is the same.

But there are differences such as the bones of the lumbar spine are thicker than the neck because the hips are lower than the neck and there is a burden.

Hip bones( lumbar spine) and nerves

When nerve bundles (spinal cord) or nerve branches (nerve roots) are compressed beyond a certain level due to various causes,

Symptoms such as pain, numbness, or difficulty in exerting force may appear from the arms to the hands or from the waist to the legs.
