The L2-L4 spinal nerves are part of the lumbar region of the spinal cord, specifically the second to fourth lumbar nerves. These nerves emerge from the spinal cord and exit the vertebral column through openings called foramina. They play a crucial role in transmitting signals between the brain and the lower body, including the legs and feet. These spinal nerves are responsible for motor and sensory functions in the lower limbs. They innervate muscles that control movement and provide sensation to the skin in areas such as the thighs and calves. Proper functioning of the L2-L4 spinal nerves is essential for mobility and coordination.
