Definition and anatomy of the vertebral body
Before talking about the vertebral laminae, it is worth briefly explaining the anatomy of the spine, And vertebrae that compose it.
La spine consists of the juxtaposition of bones called vertebrae. Also called rachis, it is separated as follows:
7 cervical vertebrae
12 thoracic (or dorsal) vertebrae
5 lumbar vertebrae
5 sacral vertebrae (forming the sacrum)
4 coccygeal vertebrae (fused)
Here is a visual diagram of the spine:
In general, each vertebrate is composed of a vertebral body in its front part, and of a posterior arch at the back formed by the pedicles and the vertebral laminae.
The lamina is therefore the part of the vertebra which connects the spinous process (often called spinous process) and the transverse process (or transverse process). There are two blades per vertebra, located on either side of thespinous process. They are present at the cervical spine, dorsal and lumbar.
The spinal lamina is often the site of surgery to relieve symptoms caused by pressure on the nerve roots. This can happen in the case of a narrow lumbar canal, or a herniated disc.
