Lumbar Plexus

The lumbar plexus is a network of nerves located in the lower back, specifically in the lumbar region of the spinal cord. It is formed by the merging of nerve roots from the first to the fourth lumbar vertebrae. This plexus gives rise to important nerves that control movement and sensation in the lower body, including the thigh and parts of the leg. Key nerves from the lumbar plexus include the femoral nerve, which helps with leg movement, and the obturator nerve, which aids in inner thigh movement. Overall, it plays a crucial role in lower body function.
