What is L2 and L5?
L2 is the lowest vertebral segment that contains spinal cord tissue. After that point, nerve roots exit each of the remaining lumbar levels beyond the spinal cord. Injuries below this level (at the L3, L4, and L5 vertebrae) affect the hips and legs and may cause numbness extending to the feet (sciatica).
What does L2 nerve control?
L2, L3 and L4 spinal nerves provide sensation to the front part of your thigh and inner side of your lower leg. These nerves also control hip and knee muscle movements.
Where is L2 L5 in the spine?
The lumbar spine makes up the the lower end of the spinal column. It consists of 5 lumbar vertebra that are numbered 1 through 5 from top to bottom i.e. L1, L2, L3, L4, and L5. The L5 vertebra is connected to the top of the sacrum (named the S1 segment) through an intervertebral disc.
What happens if the L5 nerve is damaged?
L5 NERVE ROOT DAMAGE A pinched L5 nerve root usually results in radiating pain in the foot. This pain can come in the form of numbness, tingling, weakness and shooting and is commonly felt in the big toe, inside of the foot, top of the foot and ankle.
Where does L2 cause pain?
L2-L3 Herniation: The L2 nerve root is responsible for the iliopsoas muscles. A disc herniation at this level may cause weakness in an iliopsoas muscle, which may cause difficulty while walking up the stairs and/or pain that radiates into the front of the thigh.
How does a neurologist determine if you have nerve damage?
By measuring the electrical activity they are able to determine if there is nerve damage, the extent of the damage and potentially the cause of the damage. Frequently the neurologist will recommend common, noninvasive neurological evaluations such as electromyography (EMG) and nerve conduction velocity (NCV) testing.
What pain does L2 cause?
L1 or L2 symptoms include pain in lower back and groin area and/or pain that radiate to upper front and inside of thigh. L3 or L4 symptoms include pain in lower back and /or pain that radiates to the quadriceps in the front of the thigh.
What is L2 L3 and L4?
L2 is the lowest vertebral segment that contains spinal cord tissue. After that point, nerve roots exit each of the remaining lumbar levels beyond the spinal cord. Injuries below this level (at the L3, L4, and L5 vertebrae) affect the hips and legs and may cause numbness extending to the feet (sciatica).
What is the difference between L2 and lumbar vertebrae?
It is also important to understand that the lumbar vertebrae are much different than the upper segments of the spine because the spinal cord does not extend the entire length of the lumbar spine. L2 is the lowest vertebral segment that contains spinal cord tissue.
What are L3 L4 and L5 vertebrae injuries?
Injuries below this level (at the L3, L4, and L5 vertebrae) affect the hips and legs and may cause numbness extending to the feet ( sciatica ). It may also harm the tip of the spinal cord known as the caudal equina, which is a bundle of spinal nerves and nerve roots that innervate the lower lumbar spine to the sacrum.
What is L5 lumbarization?
The L5 vertebra is the final section of the lumbar spine (at least, it is for most people). Injury to the L5 spinal nerve bundle can cause numbness and weakness in the legs, but the extent of these symptoms can vary from case to case. What is Lumbarization? The Rare Sixth Lumbar Vertebra
