FEMALE REPRO 2 Flashcards
UTERINE CYCLE what is uterine cycle
series of events that prepares uterus for implantation of zygote
UTERINE CYCLE what are 3 phases of uterine cycle
- proliferation phase
- secretory phase
- menstrual phase
UTERINE CYCLE what plays key role in menstrual cycle
hormones secreted during ovarian cycle (estrogen + progesterone)
UTERINE CYCLE what is the function of estrogen in uterine cycle
induce endometrium proliferation
UTERINE CYCLE what is the function of progesterone in uterine cycle
causes endometrium to become secretory
UTERINE CYCLE what does endometrium contain
- stratum functionalis
2. stratum basalis
UTERINE CYCLE what happens to stratum functionalis during uterine cycle
- built up towards lumen
2. shed
UTERINE CYCLE what makes stratum basalis diff from stratum functionalis
does not get shed
ENDOMETRIAL BLOOD SUPPLY what do radial arteries extend towards
endometrium
ENDOMETRIAL BLOOD SUPPLY what is the function of straight arteries
supply stratum basilis
ENDOMETRIAL BLOOD SUPPLY what is the function of spiral arteries
supply stratum functionalis
ENDOMETRIAL BLOOD SUPPLY how are straight arteries diff from spiral arteries
straight ==> do not regrow and shed
spiral ==> regrow + shed
ENDOMETRIAL BLOOD SUPPLY what happens when corpus luteum is degraded
- loss of progesterone
- spiral artery smooth muscle spasms
- endometrium becomes ischemic (no oxygen)
- endometrium dies
- endometrium sheds
what is the function of FSH in ovarian cycle
- follicular maturation
how is follicular maturation linked to proliferative phase of uterine cycle
- estrogen
- induces endometrium proliferation
what is the function of LH in ovarian cycle
- causes ovulation
how is ovulation linked to secretory phase
- progesterone
- causes endometrium to become secretory
hCG what is the function of hCG in first trimester
- replace LH
- hCG will maintain corpus luteum instead of LH
hCG what is the function of placenta in second trimester
- replace ovaries
- placenta will take over hormone secretioninsread of ovaries
what hormones will placenta secrete
- estrogen
- progesterone
- relaxin
hCG what is the function of placenta
connect foetus to uterine wall
hCG what are 6 functions of placenta
- allow nutrient intake
- allow thermoreg
- allow waste elimination
- allow gas exchange
- fight against infection
- produce hCG
CERVIX what kind of epithelial cells does cervix contain
columnar
CERVIX what do columnar cells of cervix secrete
mucous
CERVIX what is the function of mucous
prevent vaginal bacteria from entering
CERVIX what does mucous have an effect on
sperm motility
CERVIX what happens to cervix during child birth
relaxin from placenta causes cervix to dilate
VAGINA what is vagina
elastic + muscular tube
VAGINA where does vagina start and end
cervix
vestibule to external genitalia
VAGINA what is vaginal fornix
where vaginal canal surround cervix
VAGINA what innervation does vagina have
- somatic
2. autonomic
VAGINA what are functions of vagina
- eliminate menses
- sex
- form birth canal
VAGINA what kind of epithelial cells does vagina contain
stratified squamous epithelium
VAGINA what makes vagina acidic
- waste produced by resident bacteria
2. lactic acid
VAGINA how does vagina protect itself
- acidic pH
2. thick lamina propina
UTERUS what is mesometrium
broad ligament (parietal p) surrounding uterus
UTERUS what is myometirum
3 layers of smooth muscle
UTERUS what is function of myometrium
- contraction during shedding of endometrium
2. contraction during child birth
UTERUS what is endometirum
uterine lining
UTERUS what do uterine glands open into
endometirum
UTERUS what is the function of uterine gland secretions
prepare endometirum for implantation
UTERUS where do ovarian vessels come from
abdominal aorta
UTERUS what do ovarian vessels supply
- ovaries
2. fallopian tubes
UTERUS where do uterine vessels come from
internal iliac vessels
UTERUS where do vaginal vessels come from
internal iliac vessels
what do internal iliac vessels supply
pelvis
HOMOLOGUES what does body of penis contain
- corpora cavernosa x2
2. corpora spongiosum x1
HOMOLOGUES what does body of clitoris contain
corpora cavernosa x2
HOMOLOGUES what are bulb homologues
- bulb of penis (1)
- bulbs of vestibule (2)
HOMOLOGUES what are bulbs of vestibule equivalent to
corpus spongiosum
HOMOLOGUES what are crus homologues
- crus of penis
- crus of clitoris
HOMOLOGUES what are gland homologues
- bulbourethral
- greater vestibular
HOMOLOGUES what is the function of ischiocavernous muscle
- cover corpora cavernosa
HOMOLOGUES what is the function of bulbospongiousus muscle
- cover bulbs of vestibule
- cover greater vestibular glands
HOMOLOGUES what is female homologue for prostate gland
skene’s gland
INNERVATION what are 2 types of upper innervation
1 sympathetic
2. parasymptathetic
