True/False - September 9, 2011

  1. The sacrotuberous ligament is anterior to the sacrospinous ligament.
  2. The urogenital hiatus includes the urethra as an effluent but not anal canal.
  3. The piriformis muscle originates from the posterior surface of the sacrum.
  4. The ischiococcygeus (coccygeus) takes origin from the internal surface of the sacrospinous ligament.
  5. The puborectalis muscle attaches to the anococcygeal raphe and, thus, is tethered to the coccyx.
  6. The inferior fascia of the pelvic diaphragm blends with the superior fascia of the urogenital diaphragm at the urogenital hiatus.
  7. An equation; the pelvic diaphragm minus the ischiococcygeus equals the levator ani.
  8. Contraction of the ischiococcygeus raises the pelvic floor (push upward on the pelvic floor from the ischiorectal fossa in the laboratory).
  9. The iliac crest contributes the superior boundary of the true pelvis.
  10. The sacral promontory contributes to a boundary of the true pelvis.
  11. The arcuate line contributes a boundary of the true pelvis.
  12. The ischial spines in the female are oriented more laterally than in the male.
  13. The fifth lumbar vertebra couples the weight of the upper body to the sacrum.
  14. The topography of the female, pelvis relative to the male pelvis, accounts for the higher incidence of femoral hernias in the female.
  15. The puborectalis muscle is inferior the to the pubococcygeus muscle.
  16. The puborectalis, when contracted, enforces an angle at the anorectal junction that contributes to continence.
  17. The urethral crest is a raised part of the anterior membranous urethra.
  18. The bulbourethral glands drain into the prostatic sinuses.
  19. The bulbourethral glands drain into the membranous urethra.
  20. The arcus tendineus is a specialization of the obturator externus muscle that provides a site of attachment for the iliococcygeus muscle.
  21. The transversalis fascia of the pelvis, know as parietal pelvic fascia, is applied to the superior fascia of the pelvic diaphragm.
  22. The parietal pelvic fascia covers the inferior fascia of the pelvic diaphragm and lines the walls of the ischiorectal fossa.
  23. The prostatic ducts are lateral to the ejaculatory ducts at the urethral crest.
  24. The ejaculatory ducts are lateral to the utricle.
  25. The seminal colliculus of the urethral crest is medial to the prostatic sinuses.
  26. The utricle and and the ejaculatory ducts, but not the prostatic ducts, are topographies of the seminal colliculus.
  27. The fascia of Denonvilliers' is a thickening of parietal visceral fascia.
  28. The perivisceral fascia of the rectum is opposed to the fascia of Dennonvilliers'.
  29. The rectum has a convexity with the outside wall toward the right side.
  30. There is one transverse rectal fold on the right and two transverse rectal folds on the left.
  31. The convexity to the right of the rectum provides a mnemonic for which side has two transverse rectal folds and which side has one rectal fold.
  32. The location of the descending colon on the left provides a mnemonic for knowing that the rectum has a convexity to the right.
  33. The venous drainage of the rectum is partly to the portal system and mostly to the caval system.
  34. The levator ani muscle blends with the internal anal sphincter muscle.
  35. The pectinate line is located at the inferior margin of the anal valves.
  36. Internal hemorrhoids, more so the external hemorrhoids, may develop during portal hypertension.
