Lumbar Spine Anatomy Nerves. Below this level, the remaining nerves form the cauda equina, a bundle of nerves resembling a horse’s tail. Outside the vertebral column), the spinal nerves divide into their branches:

The complex anatomy of the lumbar region is a remarkable combination of these strong vertebrae (with their multiple bony elements) linked by joint capsules, and flexible ligaments/tendons, large muscles, and highly sensitive. It also receives contributions from thoracic spinal nerve 12. The lumbar plexus is an essential collection of nerves that arise from mostly the lumbar spinal cord.

The cervical spinal nerves differ from this pattern. There are many nerves that serve the lumbar region. The l4 spinal nerve roots exit the spinal cord through small bony openings (intervertebral foramina) on the left and right sides of the spinal canal. The intervertebral discs, along with the laminae, pedicles and articular processes of adjacent vertebrae, create a space through which spinal nerves exit.
