Shortly after a spinal nerve exits the intervertebral foramen, it branches into the dorsal ramus, ventral ramus, and rami communicantes.
The primary benefit is supposed to be the opening of the intervertebral foramen, the stretching of ligmentous structures, and the distraction of the apophyseal joints.
Researchers are investigating the possibility of growing new intervertebral structures through the use of injected human growth factors, implanted substances, cell therapy, and tissue engineering.
It is also abundant in corneas, cartilage, bones, blood vessels, the gut, intervertebral discs and the dentin in teeth.
The notochord disappears in the sclerotome (vertebral body) segments, but persists in the region of the intervertebral discs as the nucleus pulposus.
Posteriorly, it is separated from the lumbar vertebr and intervertebral fibrocartilages by the anterior longitudinal ligament and left lumbar veins.
The plexus is formed lateral to the intervertebral foramina and passes through psoas major.
In the thoracic region they are posterior to the pedicles, intervertebral foramina, and articular processes.
