Lumbrosacral plexus

The anterior divisions of the lumbar nerve, sacral nerve, and coccygeal nerves form the Lumbrosacral plexus or lumbosacral plexus, the first lumbar nerve being frequently joined by a branch from the twelfth thoracic. For descriptive purposes this plexus is usually divided into three parts:


 * Lumbar plexus
 * Sacral plexus
 * Pudendal plexus
