Ilioinguinal nerve

The nerve is a nerve ilioinguinal, which rose from the lumbar part ( lumbar plexus ) of the lumbar cross - braid ( lumbosacral plexus ). It innervates parts of the abdominal muscles and the skin of the scrotum or labia.

Course

The nerve passes initially focus on forward of the musculus psoas major musculus quadratus lumborum on the. Something cranial to the iliac crest, he pierced the musculus transversus abdominis and then draws between this muscle and the musculus obliquus internus abdominis after ventral. As the nerve iliohypogastricus he pulls parallel to the inguinal ligament, but within the inguinal canal medially.

Coverage area

With its motor branches ( rami musculares ) it supplies the caudal portions of the musculus transversus abdominis and the internal oblique muscle.

With the front scrotum nerves ( Nervi scrotales anterior ) it supplies the man's skin on the abdomen and the scrotum ( scrotum ). The corresponding nerve branches in the female are called anterior labial nerves ( Nervi labial anterior ) and supply the labia majora. These sensory branches also supply the skin on the lower abdomen.

Clinic

Through its close topographic relationship to the kidneys, it may, for operations on this organ come to damage of the nerve. Irritation of the nerve ilioinguinal in the groin may spread to the kidneys.
