Ch 27 part 2 female Flashcards
The uterosacral ligament functions
anchors uterus posteriorly
Mesovarium (around the ovaries- broad ligament) function
suspends the ovary anteriorly
The ovarian ligament function
anchors the ovary medially to the uterus
what hormones to the gonads produce? (ovaries)
estrogens, estradiol, estereone, estriole and progesterone
Layers of ovaries (outer to inner)
surface epithelium (simple cubodial cells)
tunica albuginea
cortex
Medulla
The Fallopian tubes are the site of _______.
fertilization
Is the uterine tube physically connected to ovary ?
No when the ooctye is released it goes into body cavity and if fertilized then it goes into Fallopian tube
The fallopian tube contains _____ and _____ muscle to create ____
cilia, smooth, peristalsis
Three regions of fallopian tube
infundibulium
ampulla
isthmus
ovary contains _____ which is a finger like structures to increase surface area that funnel oocyte into Fallopian tube
fimbriae
3 layers of the uterus (outer to inner)
Perimetrium
myometrium
endometrium
Perimetrium (uterus)
Outerlayer - serous and incomplete (thicker in some places)
myometrium (uterus)
Middle layer, muscular provides contractions at labor
endometrium (uterus)
inner layer: muscosal lining, simple columnar epithelium, deeper lamina propria, sheds each month
The superior rounded regions of uterus is the:
Fundus and lumen (cavity)
The 2 layers of the endometrium
Functional (sheds each month) and basal (unresponsive to hormones)
Flow of blood / vascular supply
- Internal iliac from pelvis 2. uterine arteries 3. arcuate arteries 4. radial artery 5. straight arteries 6. spiral arteries
Spiral arteries…
regenerate and degenerate, they constrict causing menstruation
Ph level of uterus
acidic because of bacteria that produces lactic acid to prevent infection (prior puberty is not acidic)
Layers of vaginal wall
fibroelastic adventitia
smooth muscle (muscularis)
stratified squamous mucosae with rugae
fibroelastic adventitia (vagina)
lots of movement, no glandular tissue, just cervical mucus
muscularis (vagina)
smooth muscle, can contract
stratified squamous mucosa with rugae
deep layer, non keratinized, multiple layers deal with friction. rugae in organs collapse and expand
mammary glands function
milk production: vitamins, nourishment immunity
How many lobes in sweat glands?
15-25 lobes
Suspensory ligaments in mammary glands
overlying skin with overlying muscle to hold breast
the lobe in mammary gland
alveoli sac in lactiferous duct
lactiferous sinus in mammary gland
collecting area when nursing
flow of liquid in mammary gland
alveoli (lobules) —> lactiferous ducts —-> lactiferous sinus—->opening of lactiferous duct
Ovulation occurs
midcycle between phases, monthly every 28 days
ovulation is
the maturation of an egg
Follicular phase
period of vesticular follicle phase (days 1-14)
luteal phase
period of corpus luteum activity (days 14 -28)
The luteal phase is always ____ days from ovulation to end of cycle
14 days
ovarian cycle
Primordial into Primary (cubodiol)
Primary into secondary (multiple layers now surround the follicle
Early follicle : clear liquid starts to accumulate between the granular cells, continually accumulates and expands. liquid that accumulates in the antrum.
Liquid expands pushes oocyte to edge of ovary and ovulation occurs
the rupture follicle that remains (corpus luteum) fills up with blood and becomes a gland (secretes estrogen and progestron)
During the follicular phase the hypothalamus releases more
Gnrh and Lh for sex hormone production
During the follicular phase, the cells will become ______ and then ____
androgens, (male sex but converted into Estrogens)
Fertilization occurs in
fallopian tube, and implants in uterus
In fertilization the secondary oocyte completes
meosis 2
Placenta is composed of
maternal and embryonic tissue
the placenta secretes
estrogen and progesterone
If fertilzation does not occur
progesterone and estrogen levels drop
and menstruation occurs
3 phases of uterine cycle
menstrual (endometrium is shed)
proliferative (endometrium is rebuilt)
secretory (after ovulation, enrichment of blood supply and secretion of nutrients)
