It pierces the anterior layer of the sheath of the vessels and the [[fascia lata]], and supplies the skin of the anterior surface of the upper part of the [[thigh]]. On the front of the thigh it communicates with the anterior cutaneous branches of the [[femoral nerve]]. A few filaments from the lumboinguinal nerve may be traced to the femoral artery. ==Additional images== <gallery> Image:Gray546.png|Structures passing behind the inguinal ligament. </gallery> ==External links== * {{WaynesburgAnatomicModel|nerves/lumboinguinalnerve}} {{Gray's}} {{Lumbosacral plexus}} [[Category:Nervous system]] {{neuroscience-stub}}
