: Answers to Questions for the Inguinal Canal : True/False - August 26, 2011 : 1. The external oblique contributes fibers to the formation of the linea alba, inguinal ligament, and the posterior wall of the rectus sheath. : False : linea alba-yes : inguinal ligament-yes : rectus sheath-no, only contributes fibers to the anterior border of the rectus sheath : 2. The external oblique contributes fibers to the formation of the superficial inguinal ring, the reflected inguinal ligament, and the cremasteric fascia. : False : Superficial inguinal ring—yes, triangular opening in aponeurosis of external oblique : Reflected inguinal ligament-yes : Cremasteric fascia—no, derived from the internal oblique : 3. The external oblique contributes fibers to the formation of the pectineal ligament, lacunar ligament and the conjoint tendon. : False : pectineal ligament—yes, extension of lacunar ligament, which is an extension of inguinal ligament, which is the lower border of the external oblique : lacunar ligament—yes, extension of the inguinal ligament which is the lower border of the external oblique : conjoint tendon—no, combination of transversus abdominis and internal oblique muscles : 4. The external oblique contributes fibers to the boundaries of the superficial ring, femoral ring, and the deep ring. : False : Superficial ring-yes, triangular opening in aponeurosis of external oblique : Femoral ring-yes, the inguinal ligament : Deep ring-no,opening in the transversalis fascia : 5. The external oblique contributes fibers that define three of the four boundaries of the femoral ring. : False-only the inguinal ligament borders the femoral ring : 6. The intercrural fibers secure the aponeuronsis of the external oblique to the conjoint tendon of the internal oblique. : False-intercrural fibers prevent the widening of the superficial ring : 7. The internal oblique and the transversus abdominis arise, in part, from the external oblique. : True : Internal oblique—yes, originates, in part, from the lateral half of the inguinal ligament : Transversus abdominis-yes, originates, in part, from lateral 1/3 of inguinal ligament : 8. The transversus abdominis muscle contributes a layer of transversalis fascia to the layers of the spermatic cord. : False : 9. The cremasteric muscle/fascia shares an innervation with the internal oblique muscle. : True-they share innervation since the cremasteric muscle/fascia arises from the internal oblique muscle : 10. The conjoint tendon has origins partly from the inguinal ligament. : False—unsure of reasoning : 11. The transversalis fascia refers to the investing fascia of the transversus abdominis muscle. : True : 12. An extended hip tightens the anterior abdominal wall and may cause strangulation of an inguinal hernia. : True-superficial and deep inguinal rings would tighten : 13. The artery of the ductus deferens is of the pelvic cavity. : True-the inferior vesical artery is an artery of the pelvis : 14. The testicular artery is of the abdominal cavity. : True-the testicular artery comes from the abdominal aorta : 15. When residing inside the abdominal cavity, the testis is retroperitoneal, but has a peritonealized surface. : True-since they are still within peritoneum : 16. The vascular supply to the non-descended testis is retroperitoneal. : True-since they are retroperitoneal : 17. The processes vaginalis is a diverticulum of transversalis fascia. : False-it is a diverticulum of peritoneum : 18. A patent processes vaginalis invites an indirect inguinal hernia. : True : 19. The transversus abdominis muscle contributes the layer of internal spermatic fascia to the spermatic cord. : True : 20. Scarpa's fascia takes on smooth muscle as it transitions into Dartos fascia. : True-Camper’s looses its fat, combines with Scarpa’s, and takes on smooth muscle fibers : 21. The processes vaginalis of the spermatic cord is deep to the internal spermatic fascia. : True : 22. The cremasteric fascia, but not the external spermatic fascia, makes up part of the spermatic cord within the inguinal canal. : False-both make up cord within inguinal canal : 23. The deep ring is located medial to the inferiorepigastic artery. : False-lateral to the inferiorepigastric artery : 24. The obliterated umbilical artery creates a fold of visceral peritoneum named the medial umbilical fold. : True : 25. The urachus obliterates to form the median abdominal ligament. : False-obliterates to form median umbilical ligament : 26. The median umbilical folds define the medial inguinal fossa between them. : False-medial inguinal fossa is between the lateral and medial umbilical fold : 27. The cremasteric artery is deep to the internal spermatic fascia and deep to the processes vaginalis. : False : Cremasteric artery is superficial to the internal spermatic fascia and processes vaginalis : 28. A patent processes vaginalis may transmit a direct inguinal hernia. : False : 29. The external spermatic fascia is in contact with Dartos fascia. : True : 30. Lymphatic drainage from the superior pole of the testis is to the upper lumbar nodes and lymphatic drainage from the inferior pole is to internal iliac nodes. : False-would follow lymphatic back to their source of blood supply, not sure which nodes : 31. The parietal layer of the tunica vaginalis is superficial to the internal spermatic fascia. : False—the parietal layer of tunica vaginalis is deep to transversalis fascia
