What Nerves Are Found in the Third and Fourth Lumbar Vertebrae?
The nerve roots for the L3 and L4 nerves pass through and leave the spinal column under the third and fourth lumbar vertebrae, respectively.

What is the third vertebra?
The third lumbar spine vertebra (L3) is located in the middle of the lumbar spine, making it particularly susceptible to wear and tear. It is one of the most common sites for causes of chronic lower back pain. Vertebrae, along with the discs in between them, provide protection for the spinal cord and nerves that run through them.
What are the problems with L3?
Age and posture may aggravate common problems with the L3, such as ligament or muscle strain. Less common problems are osteoarthritis or disc hernias. While many symptoms can be alleviated with medication or physiotherapy, surgery or other endoscopic techniques may be an option for chronic back pain.
What is the function of the vertebrae?
Vertebrae, along with the discs in between them, provide protection for the spinal cord and nerves that run through them. At L1 level, the true spinal cord ends, dividing into nerves called the cauda equina, which run to the lower body and extremities.

How to treat lumbar nerve compression?
The goal of lumbar spine surgery is typically aimed at relieving compression of a nerve root and/or the cauda equina. Surgical options may include: 1 Microdiscectomy. A small part of the disc material near the nerve root is taken out. A portion of the bone adjacent to the nerve root may also be trimmed to relieve compression.#N#See Microdiscectomy (Microdecompression) Spine Surgery 2 Laminectomy. The lamina (area of bone at the back of the vertebra) is removed in order to provide more room for the cauda equina.#N#See Lumbar Laminectomy Surgery for Spinal Stenosis (Open Decompression) 3 Foraminotomy. The opening for the spinal nerve root (intervertebral foramen) is enlarged by trimming bony overgrowth, relieving nerve compression. 4 Facetectomy. Trimming and/or removing a part of the facet joints and/or bony overgrowths to relieve nerve root compression. 5 Fusion of L3-L4. Depending on the extensiveness of the surgery and the amount of bone removed, the surgical segment may be fused with the adjacent motion segment to provide stability.#N#See Lumbar Spinal Fusion Surgery 6 Lumbar artificial disc replacement. This surgery is not very common and includes a complete replacement of the lumbar intervertebral disc to relieve nerve root compression and replace it with an artificial implant.#N#See Lumbar Artificial Disc Replacement for Chronic Back Pain

What is the role of the L3-L4 spinal segment?
The L3-L4 spinal motion segment, positioned in the middle of the lumbar spine, plays an important role in supporting the weight of the torso and protecting the cauda equina (nerves that descend from the spinal cord). While the L3-L4 motion segment is less likely to be injured compared to its lower counterparts, it may be subject to degeneration, trauma, and disc-related problems.

What is the region between the transverse process and the vertebral body called?
The region between the transverse process and the vertebral body is called the pedicle. The L3 and L4 vertebrae are connected at the back by a pair of facet joints (zygapophyseal joints), which are covered by articulating cartilage to provide smooth movements between the joint surfaces. L3-L4 intervertebral disc.
Why is the L3 L4 herniated?
Disc problems. The L3-L4 disc may degenerate or herniate due to age-related changes or from trauma. When subject to acute trauma, the L3-L4 motion segment may rarely undergo facet joint dislocation, fracture, and/or damage to the cauda equina. Rarely, tumors and infections may affect the L3-L4 motion segment.
