: : 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 : Agree. : : 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 : Agree. : : 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 : Agree. : : 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 : Agree. : : 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 : True. Three of four boundaries of the femoral ring are contributed by the external oblique. Lacunar and Pectineal ligaments are from external oblique. : : 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 : Agree. By approximating the medial and lateral crural fibers. : : 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 : Agree. Generally said to be lateral 2/3 for the internal oblique. : : 8. The transversus abdominis muscle contributes a layer of transversalis fascia to the layers of the spermatic cord. : : False : Agree. The transversus does not give rise to the transversalis fascia nor does it present a barrier to the deep ring. : : 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 : Agree. : : 10. The conjoint tendon has origins partly from the inguinal ligament. : : False—unsure of reasoning : True. Both the internal oblique and the transversus abdominis arise, in part, from the inguinal ligament. : : 11. The transversalis fascia refers to the investing fascia of the transversus abdominis muscle. : : True : False. The transversalis fascia is a specialization of endocavital fascia. It is not investing fascia. : : 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 : Agree. May strangle femoral hernia as well. : : 13. The artery of the ductus deferens is of the pelvic cavity. : : True-the inferior vesical artery is an artery of the pelvis : Agree. Thus, where is the primary lymph drainage from the tail of of the epididymis? The autonomic supply? : : 14. The testicular artery is of the abdominal cavity. : : True-the testicular artery comes from the abdominal aorta : Agree. Thus, where is the primary lymph drainage from the testis? The autonomic supply? : : 15. When residing inside the abdominal cavity, the testis is retroperitoneal, but has a peritonealized surface. : : True-since they are still within peritoneum : Agree. Within the peritoneum? Nothing, except for an episodic egg, is in the non-pathological peritoneal cavity. The peritonealized becomes the visceral tunica vaginalis. : : 16. The vascular supply to the non-descended testis is retroperitoneal. : : True-since they are retroperitoneal : Agree. : : 17. The processes vaginalis is a diverticulum of transversalis fascia. : : False-it is a diverticulum of peritoneum : Agree. : : 18. A patent processes vaginalis invites an indirect inguinal hernia. : : True : Agree. RSVP : : 19. The transversus abdominis muscle contributes the layer of internal spermatic fascia to the spermatic cord. : : True : False. The transversus abdominis does not present a barrier to the descent (metaphor). The transversalis fascia is not of the transversus abdominis. : : 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 : Agree. Any thoughts about innervation? That's a killer. : : 21. The processes vaginalis of the spermatic cord is deep to the internal spermatic fascia. : : True : Agree. : : 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 : False. The external spermatic fascia is from the external oblique. It begins distal to the superficial ring. : : 23. The deep ring is located medial to the inferior epigastic artery. : : False-lateral to the inferiorepigastric artery : Agree. : : 24. The obliterated umbilical artery creates a fold of visceral peritoneum named the medial umbilical fold. : : True : False. Parietal peritoneum. : : 25. The urachus obliterates to form the median abdominal ligament. : : False-obliterates to form median umbilical ligament : Agree. : : 26. The median umbilical folds define the medial inguinal fossa between them. : : False-medial inguinal fossa is between the lateral and medial umbilical fold : Agree. There is only one median umbilical fold. Between the medial umbilical folds is the supravesical fossa. : : 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 : Agree. Nothing is deep to the processes vaginalis. Maybe you could argue the testicular coelom, but not very effectively. : : 28. A patent processes vaginalis may transmit a direct inguinal hernia. : : False : Agree. : : 29. The external spermatic fascia is in contact with Dartos fascia. : : True : Agree. : : 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 : True. This is the source of the blood supply. : : 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 : Agree. The internal spermatic fascia is derived from the transversalis fascia but, by definition, it is not transversalis fascia if it is not lining the abdominopelvic cavity.
