Ilioinguinal Nerve

  • Amgad S. Hanna

Abstract

The ilioinguinal nerve arises from the ventral ramus of L1. It emerges from the lateral aspect of the psoas muscle cranial to the lateral femoral cutaneous nerve. It courses in the retroperitoneum and then pierces the transversus abdominis at the lateral part of the iliac crest to course between the transversus abdominis and internal oblique muscles. More anteriorly, it pierces the internal oblique to lie between this muscle and the external oblique , below the spermatic cord (or round ligament of the uterus). It supplies the skin of the medial groin, medial upper thigh, upper scrotum, and root of the penis (mons pubis and labium majus in females) as well as the abdominal wall muscles.
