: Questions for the Inguinal Canal
: These questions were not submitted by the lecturer.
: August, 2009
1. The prostate is easier to palpate than is the breast.
Um...define easier? Simpler, yes.
2. Compression of the prostate may effect the delivery of fluids from the vas deferens to the urethra.
T - since this can squash both the urethra and the vas deferens. Hypertrophy of the prostate can also cause this.
3. The medial and lateral crura together with the intercrural fibers contribute to the anterior wall of the inguinal canal.
T
4. The inferior boundary of the superficial ring is superior and medial to the pubic tubercle.
F - superior and lateral
5. The femoral ring is inferior and lateral to the pubic tubercle.
F? - lateral and almost on the same plane, but slightly superior?
6. A derivation of the external oblique aponeurosis applies to the pectin pubis (pectineal line).
T
7. A derivation of the internal oblique aponeurosis contributes the lacunar ligament.
F - internal oblique contributes to conjoint tendon, external oblique contributes to lacunar ligament
8. The external spermatic begins after the deep ring of the inguinal canal.
External spermatic what?
9. An oblique course is advantageous for thwarting herniation.
T
10. Arising from the lateral 2/3 of the inguinal ligament is the external oblique muscle whereas arising from the lateral 1/3 is the transversus abdominis.
T - although the external oblique forms the medial 1/3 as well
11. The cremasteric fascia and muscle is derived from the transversus abdominis muscle.
F - from the internal oblique
12. The transversalis fascia, the epimysium of the transversus abdominis muscle, contributes the external spermatic fascia.
F - to the internal spermatic fascia
13. An inferior free edge of the transversus abdominis muscle is superior to the deep ring.
T
14. The conjoined tendon is formed by a joining of the of the internal and external oblique muscles.
F - the joining of the internal and transversus
15. The testis, at 3 mo fetal has a a peritonealized surface, is retroperitoneal and is located near the kidney,
T
16. The peritonealized surface of the testis becomes the parietal layer of tunica vaginalis.
T
17. A distal part of the processes vaginalis becomes the visceral layer of tunica vaginalis.
T
18. The gubernaculum becomes the scrotal ligament.
T
19. An indirect hernia that descends to the tunica vaginalis can be palpated at the anterior margin of the testis.
T - sometimes. It can depend on the size and extent of the hernia.
20. The obliterated umbilical arteries raise a peritoneal fold know at the medial umbilical fold
T - but, "folds." These are paired.
21. A remnant of the urachus raises a peritoneal fold known as the median umbilical fold.
T
22. The obliterated inferior epigastric artery raises a peritoneal fold know as the lateral umbilical fold.
T
23. Between the median and medial umbilical folds is the paravesical fossa; a part of the medial inguinal fossa.
F - medial inguinal fossa?
24. Between the medial and lateral umbilical folds is the lateral inguinal fossa, typically to site of herniation for the indirect inguinal hernia.
F - indirect usually run lateral to the lateral umbilical fold, through a patent or weak processus vaginalis.
25. The outermost layer of the spermatic cord is dartos tunic.
F - dartos tunic is the innermost layer of fascia of the scrotum, not part of the spermatic cord
26. The vas deferens, deferential plexus, artery of the vas deferens, tail of the epididymis, testicular artery, pampiniform plexus, and testicular plexus, but not the cremasteric artery and the genitofemoral nerve, are within (deep to) the internal spermatic fascia.
T
27. An indirect inguinal hernia proceeds indirectly out the superficial ring by way of the deep ring and the inguinal canal.
T
28. The direct inguinal hernia proceeds directly out the superficial ring by compromising the conjoint tendon and the lateral inguinal fossa.
T
29. The indirect inguinal hernia proceeds directly down an embryological pathway and, thus, is often a congenital condition.
T
30. A hydrocele reflects a built up of fluid in the testicular coelom.
T
31. The ovarian ligament, but not the suspensory ligament of the ovary, is derived from the gubernaculum.
F - the suspensory ligament of the ovary is derived from the upper part of the gubernaculum
32. The round ligament of the uterus proceeds out the deep ring, into the inguinal canal, out the superficial ring, and then ascends to the level of the umbilicus.
F - except maybe in late pregnancy. Otherwise it runs medially to the uterine horns (which sit much lower in the pelvis than the umbilical region).
