The femoral nerve is the chief nerve of the anterior compartment of the thigh. It is the largest branch of the lumbar plexus and arises from the dorsal divisions of the anterior primary rami of L2, L3, L4 nerves.
It enters the thigh posterior to the inguinal ligament just lateral to the femoral artery. About 2 cm below the inguinal ligament it divides into anterior and posterior divisions which are separated by the lateral circumflex femoral artery. Before passing posterior to the inguinal ligament gives of a branche to iliacus muscle and a branch to pectineus muscle.
