Module 17 - The female reproductive system Flashcards
The ovaries are anchored to the pelvic cavity by several folds of:
Name the three structures.
peritoneum
-Broad ligament
-Suspensory ligament
-ovarian ligament
List the uterine tube parts in order from closest to the ovary to closest to the uterus
fibriae → infundibulum → ampulla → isthmus → uterine part → uterine cavity
In what section of the uterine tube does fertilization usually occur?
the ampulla
What makes up the myometrium?
smooth muscle
The uterine artery is a branch off the _____________ artery whereas the ovarian artery is a branch off the __________
internal iliac; abdominal aorta
What are the two recesses and how are they formed?
-pouches formed by peritoneal folds - vesicouterine (uterus and bladder) and rectouterine
What kind of epithelial tissue makes up the vagina?
stratified squamous
What kind of connective tissue is found in the cervix?
collagen fibers
The labia majora is homologous to what male structure?
the scrotum
The _____ of the mammary glands produce milk
alveoli
THe cervix have glands that secrete protective ____
mucus
The primary female sex organ is :
ovaries
The ovaries are intra/retroperitoneal?
intraperitoneal
The ovarian gonadal artery branches off?
the descending aorta just inferior to the renal arteries and is drained by the ovarian vein
What is the typical SITE for fertilization?
the uterine tubes
How log does it take for the oocyte to travel the length of the uterine tube and reach the lumen of the uterus?
3 days
What covers the inner longitudinal and outer circular layers of the uterine tubes?
muscularis smooth muscle
What are the four regions of the uterus?
-fundus
-body
-isthmus
-cervix
What is the typical position of the uterus?
anteverted (towards bladder)
T/F: The lumen is continous with the uterine tubes and vagina
true
What is the uterine wall composed of?
Perimetrium: outermost visceral layer covered by CT
Myometrium: middle thickest layer made of smooth muscle that can cause period cramps
Endometrium: the innermost layer that can thicken under the influence of hormones
What is endometriosis?
tissue similar to endometrial tissue exists outside of the uterus and sheds on whatever organ is present, causing severe pain
What is an ectopic pregnancy?
occurs when a fertilized egg implants outside the uterus, typically in one of the fallopian tubes
Lateral cervical ligaments:
Round ligaments:
Uterosacral ligaments:
-restrict inferior movements of the uterus
-helps the uterus stay anteverted
-connect inferior uterus posteriorly to the sacrum
What is the vaginal orifice?
opening of the vagina
The vulva is our:
external genitalia (everything we see on the outside)
What is the fatty pad that overlies the pubic symphysis?
the mons pubis
The paired, thickened folds of skin are the:
labia majora
The labia minora:
is paired, hairless folds medial to the labia majora
What is the prepuce?
the external fold of the labia minora that covers the clitoris
The lactiferous ducts drain the ________ while the lactiferous sinuses drain the ___________
alveoli; lactiferous ducts
