Heart-shaped, resembles male pelvis

Front 12

What are some major differences between the male/female pelvis?

Back 12

Female pelvis is larger in capacity; intertuberosity distance is larger; ischial spines project less into birth canal; ilium flares more; sacrum is shorter and wider, pubic angle is larger

Front 13

What are the diameters of the pelvis?

Back 13

Conjugate (true and diagonal), transverse, and oblique

Front 14

What is the pelvic diaphragm?

Back 14

A muscle shelf separating pelvis from perineum

Front 15

What is the rectovesical pouch?

Back 15

Between the rectum and the bladder the peritoneal cavity forms, in the male, a pouch, the rectovesical excavation (or rectovesical pouch)

Front 16

What forms the broad ligament (females?)

Back 16

The peritoneum that drapes down over the uterine tubes (aka oviducts) to form a connection from lateral side of uterus to pelvic wall

Front 17

What seals off the obturator foramen?

Back 17

Obturator membrane

Front 18

What is the origin of obturator internus and externus?

Back 18

Obturator membrane

Front 19

Which of these is the true pelvis? The false pelvis?

Greater
Lesser

Back 19

Greater = False (more superior)
Lesser = True

Fun fact - called "false" pelvis because it is not relevant to childbirth

Front 20

Which pelvic shape presents the least difficulty during childbirth and why?

Back 20

The gynecoid. The circular shape.

Front 21

Which pelvic shape presents the MOST difficulty during childbirth and why?

Back 21

Platypelloid. Elongation in the transverse direction (wider and flatter)

Front 22

What are the boundaries of the <b>true conjugate</b> diameters?

Back 22

This is an AP plane diameter.

tip of the sacral promontory to the upper border of the symphysis pubis.
"

Front 23

What are the boundaries of the <b>diagonal conjugate</b> diameters?

Back 23

From the tip of sacral promontory to the lower border of symphysis pubis.

1.5 cm longer than the true conjugate.

Front 24

What is the rectovesical pouch part of?
A) Peritoneum
B) Pelvis
C) Perineum

Back 24

Peritoneum

Front 25

What is the broad ligament of the uterus made from?

Back 25

The peritoneum that drapes down to form a connection from the lateral side of the uterus to the pelvic wall

Front 26

What is the posterior fornix of the vaginal canal? What is it useful for clincially?

Back 26

larger recess, behind the cervix. It is close to the rectouterine pouch, so it's where you insert a needle to drain it.

Front 27

What is a strong band that stretches between the spine of the ischium and the superior pubic ramus?

Back 27

Arcus tendineus: origin of levator ani, specialization of the fascia of obt. internus.

Front 28

What is the mesovarium?

Back 28

A specialization of the broad ligament of uterus that covers the ovaries. (mesOVARIum)

Front 29

What is the mesosalpinx?

Back 29

portion of the broad ligament that stretches from the uterine tube to the level of the ovary.

Front 30

What is the cardinal ligament/what does it do?

Back 30

located at the base of the broad ligament of the uterus. Importantly, it contains the uterine artery and uterine vein. There is a pair of cardinal ligaments in the female human body.

It attaches the cervix to the lateral pelvic wall at the ischial spine, and is continuous externally with the fibrous tissue that surrounds the pelvic blood vessels. It thus provides support to the uterus

Front 31

What is the relation of the ureter to the uterine vessels?

Back 31

Below/inferior
"Water under bridge"

Front 32

How does the vas deferens enter the pelvis?

Back 32

Deep inguinal ring

Front 33

When the vas deferens passes the ureter to join the seminal vesicle, where is the ureter in relation to it?

Back 33

Inferior

Front 34

What does the vas deferens enlarge to form?

Back 34

Ampulla

Front 35

What is the male homologue of the female uterus and vagina?

Back 35

prostatic utricle

Front 36

Is the deep dorsal vein of penis paired?

Back 36

NO. It's the biggest structure in the antero-medial penis.

Front 37

Is the dorsal artery of penis paired?

Back 37

YES

Front 38

Where is the deep artery ofthe penis located?

Back 38

Pretty much right in the middle of each of the corpus cavernosum of penis. The split in the penis is called the septum.

Front 39

Is the tunica albuginea thicker on the corpus cavernosum or spongiosum parts of penis?

Back 39

Cavernosum. This is the part that expands during erection, so it supports the erection

Front 40

What do the ejaculatory ducts open into the urethra on?

Back 40

COlliculus seminalis/varumontanum: landmark near the entrance of the seminal vesicles

Front 41

Where does the ureter go in relation to uterine and vaginal a?

Back 41

ureter passes between the uterine and vaginal arteries

Front 42

What is the prostatic sinus?

Back 42

Small openings in the prostatic urethra thru which prostate gland's secretions reach the urethra

Front 43

What are the vessels of the posterior division of the internal iliac?

From superior to inferior

1) Iliolumbar
2) Lateral sacral
3) Superior gluteal

What are the vessels of the anterior division of the internal iliac?

Back 44

1) Inferior gluteal
2) Obturator (looks like a mirror image of inferior gluteal?)
