Fig. 25-8. Structure of the inguinal and femoral regions in relation to hernia. A. Horizontal section through the inguinal region. The broad orange arrow represents the course of the spermatic cord. B and C. The course of indirect and direct inguinal hernias. Note that indirect inguinal hernias follow the course of the spermatic cord and that direct inguinal hernias exit medial to the inferior epigastric artery. C. Sagittal section through the inguinal region. D. Note that femoral hernias pass ventral to the inguinal ligament to enter the thigh. T.= Transversus abdominis; I.O.= internal oblique m.; E.O.= external oblique m. The small black arrow indicates the median plane. (After Maisonnet and Coudane. The sagittal sections are based largely on Lytle.) Click for high resolution image.
