Thelumboinguinal nerve, also known as thefemoral orcrural branch of genitofemoral, is a nerve in theabdomen. The lumboinguinal nerve is a branch of thegenitofemoral nerve. The "femoral" part supplies skin to thefemoral triangle area.
The lumboinguinal nerve arises from the genitofemoral nerve. It descends alongside theexternal iliac artery, sending a few filaments around it, and, passing beneath theinguinal ligament, enters the sheath of the femoral vessels, lying superficial and lateral to thefemoral artery. Here, it pierces the anterior layer of the sheath of the vessels and thefascia lata, and supplies the skin of the anterior surface of the upper part of thethigh.[1]: 343
On the front of the thigh it communicates with the anterior cutaneous branches of thefemoral nerve.
A few filaments from the lumboinguinal nerve may be traced to the femoral artery.
