<P> The lateral cutaneous nerve of the thigh is a nerve of the lumbar plexus . It arises from the dorsal divisions of the second and third lumbar nerves ( L2 - L3 ) . It emerges from the lateral border of the psoas major at about its middle , and crosses the iliacus muscle obliquely , toward the anterior superior iliac spine ( ASIS ) . It then passes under the inguinal ligament , through the lacuna musculorum and then over the sartorius muscle into the thigh , where it divides into an anterior and a posterior branch . </P>
