What does L2 and L3 control?
L2, L3, and L4 spinal nerves provide sensation to the front part of the thigh and inner side of the lower leg. These nerves also control movements of the hip and knee muscles.
What nerves are affected by L2-L3 L4?
If a nerve is trapped at L2 or L3 or L4 this will affect the femoral nerve (as seen below) and we suffer from femoral nerve impingement which provides both feeling and power to the front of the thigh. Therefore we experience pain in this specific anatomy.
Where is the L2 and L3 located in the spine?
TheFacet L2-L3 disc is about 2 inches above the waist. Problems at the L2-L3 segment of the lumbar spine commonly refer to pain in the spine’s mid or lower portions.
What part of the body does L3 affect?
The L3 dermatome is an area of skin that receives sensations through the L3 spinal nerve and includes the front part of the thigh and inner part of the leg. The L3 myotome is a group of muscles controlled by the L3 spinal nerve and includes parts of specific muscles in the hip, thigh, and leg.
Where is L2 located in the spine?
The L2 vertebra is located in the lower curvature of the spine, and the portion of the spinal cord that it protects is known as the lumbar cord.
What are the symptoms of L3 disc bulge?
When the L3 spinal nerve is involved, the following symptoms may occur: Sharp pain , typically felt as a shooting and/or burning feeling that may occur in the thigh and/or inner part of the leg. 3 Abnormal sensations, such as a feeling of pins-and-needles and/or tingling. These symptoms are typically experienced in one leg.
What is L3 in the spine?
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 is L2 nerve?
The second lumbar spinal nerve (L2) originates from the spinal column from below the lumbar vertebra 2 (L2). L2 supplies many muscles, either directly or through nerves originating from L2. They may be innervated with L2 as single origin, or be innervated partly by L2 and partly by other spinal nerves.
