FEMORAL NERVE

 

ORIGIN: Ventral rami of L2-4 nerves

COURSE/DISTRIBUTION: It emerges from its ventral rami and immediately enters the belly of the psoas major to emerge at the lateral border of  that muscle,  passing between it (psoas major) and the iliacus posterior to the fascia iliaca to reach a position behind the inguinal ligament. It immediately enters the thigh and splits into numerous branches, some of which are muscular, while others are cutaneous or articular.
