Dissection of male pelvis from a lateral approach
General view of pelvic contents in situ, pelvic diaphragm reflected
The opening into the pelvis has been somewhat enlarged by the removal of more of the pubic and ischial bones and a small part of the body of the ilium. The obturator fascia has been cut away and the pelvic diaphragm has been split and reflected. Areolar connective tissue has been stripped from the underlying vessels and nerves.
  1. Periosteum of ilium
  2. Body of ilium (partially removed)
  3. Obturator artery (source of two vesical branches)
  4. Upper pointer: Parietal peritoneum (external aspect) Lower pointer: Ductus deferens
  5. Obturator nerve
  6. Iliopsoas muscle (cut off)
  7. Femoral nerve (cut off)
  8. Femoral artery and vein (cut off)
  9. Urinary bladder (external surface)
  10. Superior vesical artery
  11. Pectineus muscle
  12. Transversalis fascia
  13. Pubic symphysis (left pubic bone cut away)
  14. Suspensory ligament of the penis
  15. Glans penis (dissected)
  16. Upper pointer: Ureter Lower pointer: Pelvic ganglion (note parts of pelvic plexus associated with ureter)
  17. Sciatic nerve
  18. Inferior gluteal artery
  19. Piriform muscle
  20. Coccygeus muscle (reflected)
  21. Filaments of pelvic plexus
  22. Parietal pelvic fascia
  23. Vesical veins
  24. Branch of sacral nerve IV to levator ani muscle
  25. Levator ani muscle (reflected)
  26. Superior fascia of pelvic diaphragm
  27. External anal sphincter muscle
  28. Superior fascia of urogenital diaphragm
  29. Urethra (opened)
