The ilio-inguinal nerve appears in the field after perforating theinternal oblique at or near the internal ring and descends along thelower part of the inguinal canal; it terminates by distributing fibersto the side of the scrotum and thigh. This nerve is not constant, andoccasionally is found joined to the genital branch of the genitocruralto form the external spermatic nerve. The genitocrural nerve, its genital branch, appears at the internalring and passes down the back part of the spermatic cord into the HERNIA 349 Lateral cutane-ous branches,,fourth inter-costal nterior cutaneousbranch, secondintercostal.
