1. State some differences between the male pelvis and the female pelvis?
The pelvic inlet is more oval shaped and round in females, it is heart shaped and narrower in males
Females - ischial spines do NOT point medially, in males they do
Females - sub-pubic angle > 80 degrees, males 50-60 degrees
Females - ratio of distance between the pubic symphysis and the anterior margin of the acetabulum is 1 or > 1,
Females - true pelvis is shallow, wide and cyllindrical, males it is deep, narrow and tapers
Females - false pelvis is wide, males it is narrow
2. Describe the orientation of the pelvic girdle with reference to two bony landmarks that are in the same
ASIS and pubic tubercle are in the same vertical plane
3. True or False: the parietal peritoneum reaches the pelvic floor
False - the parietal peritoneum does NOT reach the pelvic floor
4. What is found in the space between parietal peritoneum and pelvic wall that is not occupied by viscera?
Pelvic fascia
5. What are the ligaments that support pelvic viscera made up of?
Pelvic fascial condensations
6. Describe the path of the ductus deferens from the epididymis to the urethra.
The ductus deferens goes in through the superficial inguinal ring, through the inguinal canal and out of the
inguinal ring. It then goes superior to the bladder, crosses the ureter and goes posterior to the ureter and joins
urethra through the prostate. Before joining the urethra, the ductus deferens joins with the seminal vesicle to
7. What structures can be felt in a DRE (rectal exam) of a healthy man?
Prostate and seminal vesicles. Probably not the bladder unless there is something abnormal.
8. What are the four parts of the urethra? State how long they are.
Pre-prostatic - 1.5 cm
Prostatic - 2.5 cm
Membranous - 2 cm
Spongy - 15 cm
(sometimes the parts are: prostatic, bulbar, membranous and spongy)
9. What glands are found within the urogenital diaphragm and where do these glands open into?
Bulbourethral Gland (produces secretions that lubricate the urethra and provide nutrients
10. What is the ampulla of the ductus deferens?
This is a dilation that is found just before the joining of the ductus deferens with the seminal vesicle to form
11. What three components empty into the prostatic urethra?
Seminal vesicles
Prostate
Ductus deferens
12. How many ejaculatory ducts are there
