lumbar nerve
Noun: A lumbar nerve is any one of the five pairs of spinal nerves that originate from the lumbar segment of the spinal cord. These nerves are part of the peripheral nervous system and are responsible for transmitting motor, sensory, and autonomic signals between the spinal cord and the lower back, abdomen, pelvis, and legs.
The term "lumbar nerve" is used in anatomical, medical, and clinical contexts to refer to these specific nerves. It is typically used with a number (e.g., first lumbar nerve) or collectively to describe the group. - The lumbar nerves exit the spinal column through openings between the lumbar vertebrae. - Compression of a lumbar nerve, such as the L5 nerve, can cause sciatica. - The surgeon carefully avoided the lumbar nerve during the procedure.
- Lumbar nerve root: Refers specifically to the initial segment of the nerve as it branches off from the spinal cord. Pathology here is often termed "lumbar radiculopathy."
- The MRI showed a herniated disc impinging on the L4 lumbar nerve root.
- Lumbar nerve plexus: Refers to the network where lumbar nerves (along with others) interconnect to form larger nerves like the femoral nerve.
- The lumbar nerve plexus is formed primarily from the anterior rami of the L1-L4 nerves.
- Lumbar (adjective): Pertaining to the lower part of the back between the ribs and the pelvis.
- She has lumbar pain.
- Lumbosacral (adjective): Pertaining to both the lumbar and sacral regions.
- The lumbosacral plexus is a major nerve network.
- Spinal nerve (noun): A more general term for any of the 31 pairs of nerves arising from the spinal cord. Lumbar nerves are a subset of spinal nerves.
- Each spinal nerve carries both sensory and motor information.
- Lumbar spinal nerve: A more precise, full anatomical term.
- The lumbar spinal nerves are designated L1 to L5.
- Lumbar nerve compression: A clinical condition where a nerve is pinched, often by a herniated disc or bone spur.
- Symptoms of lumbar nerve compression include pain, numbness, and weakness.
- Lumbar nerve block: A medical procedure involving the injection of anesthetic near a lumbar nerve to relieve pain.
- The patient received a lumbar nerve block for diagnostic purposes.
