Dissection of the Pelvis

  1. The dissection of the pelvis is approached superiorly as shown in this dissection. Demonstrate viscera such as the rectum, the uterus and bladder as shown in higher magnification. Use your fingers to gently separate the viscera and tie off the rectum as far down as you can reach before removal.
    NOTE: Use a double ligature! That way by cutting between the ties you minimize the amount of feces that could spill into the cavity.

  2. In both the male and female you should clean the ureters descending into the bladder and the gonadal vessels dissected earlier. As you clean the rectum, follow the superior rectal artery (branching from the inferior mesenteric a.). Clean as many of the branches of the internal iliac as you can easily reach (such as the iliolumbar a., obturator a. running with the obturator n., obliterated umbilical a. giving off the superior vesicle a.).
    NOTE: Be aware that your cadaver may have a very common variation, the abnormal obturator a., which branches from the inferior epigastric a.)

  3. Additional structures you should clean in the female include:
    NOTE: Obviously, many of these structures may have already been surgically removed in your cadaver. If that is the case, find a good example on another cadaver.

  4. Additional stuctures you should clean in the male are:
