Ilioinguinal nerve - referred pain


Genitofemoral Nerve

  1. In human anatomy, the genitofemoral nerve originates from the upper part of the lumbar plexus of spinal nerves. Its roots are L1 and L2 (lumbar).
  2. The genitofemoral nerve is responsible for both the efferent and afferentlimbs of the cremasteric reflex. The ilioinguinal nerve (L1) is also involved in the afferent limb of the reflex.
  3. It emerges on the anterior surface of the psoas major muscle and divides into two branches:
    1. The femoral branch, or lumboinguinal nerve, supplies skin anterior to the upper part of the femoral triangle
    2. The genital branch:

Obturator nerve

It descends through the fibers of the Psoas major, and emerges from its medial border near the brim of the pelvis; it then passes behind the common iliac vessels, and on the lateral side of the hypogastric vessels and ureter, which separate it from the ureter, and runs along the lateral wall of the lesser pelvis, above and in front of the obturator vessels, to the upper part of the obturator foramen.

Here it enters the thigh, through the obturator canal, and divides into an anterior and a posterior branch, which are separated at first by some of the fibers of the Obturator externus, and lower down by the Adductor brevis.

Femoral Nerve
