WEST Female Reproduction Lecture

What is the female reproductive system derived from?

Mullerian ducts

4 main functions of the female reproductive system

gamete production, hormone production, embryo support, neonatal nutrition

squamous/cubodial surface layer, does not produce germ cells

germinal epithelium

dense connective tissue beneath the epithelium of the ovary

tunica albuginea

superficial layer where oocytes are produced

cortex

deep vascular core containing blood vessels and nerves

medulla

4 structures that stabilize the ovary?

ovarian ligament, mesovarium, suspensory ligament, broad ligament

extends from uterus to the medial surface of the ovary to hold ovary to the uterus

ovarian ligament

fold of mesentery providing direct ovarian support

mesovarium

extends from lateral ovary surface to the pelvic wall, carries ovarian vessels

suspensory ligament

extensive mesentery enclosing ovaries, uterine tubes, and uterus, attaches to pelvic sides and floor

broad ligament

3 structures of the fallopian tubes

infundibulum, ampulla, and isthmus

funnel-shaped end with fimbriae that reiceve the oocyte

infundibulum

widest segment and the usual site of fertilization

ampulla

narrow segment that moves contents toward the uterus

isthmus

What hormone increases ciliation in the fallopian tubes

estrogen

What hormone makes the lining of the fallopian tubes more secretory

progesterone

a hollow muscular organ that supports protection, nutrition, and waste removal for the embryo/fetus

uterus

name for the rounded top of the uterus

fundus

What parts of the female reproductive system is not sterile?

vagina

Why is it important to not poke the fundus?

It can cause contractions

3 layers of the uterine wall

perimetrium, myometrium, endometrium

outer incomplete serosal layer of uterus, continuous with the peritoneal lining

perimetrium

thick smooth muscle layer of the uterus

myometrium

what hormone drives uterine contractions?

estrogen

What hormone keeps the uterus quiescent?

progesterone

glandular inner lining with functional zone and basilar zone

endometrium

What happens to the functional zone during menses?

shed

What is the basilar zone?

regenerative base

what is the minimum thickness of the endometrium needed for FET?

8mm

Order the uterine vasculature from largest to smallest

uterine, arcuate, radial, straight, spiral

Which artery is the main blood supply to the uterus?

uterine

which artery encircles the endometrium?

arcuate

Which artery penetrates inward to supply the endometrium?

radial

Which artery supplies the basilar zone?

straight

Which artery supplies the functional zone and sheds during menstruation?

spiral
