Signal outflow in the foreroot of the 3rd lumbar spinal cord segment

Radix ventralis L3; signal outflow.

The foreroot filaments L3 run out into the spinal nerve L3 which participates in the formation of the lumbar-pelvic braid (lumbo-sacralis plexus). The foreroot threads from the spinal cord segment L3 affect, among other things, the hip, thigh and gluteal muscles.
