ch 1 female repro contraception Flashcards
3 layers of uterus from inner to outer
endometrium
myometrium
perimetrium
clusters of epithelial cells within lobules of breasts that secrete colostrum and milk
clusters of acini
changes in breasts throughout menstrual cycle (3)
sensitivity
size
nodularity
when should women do self breast exams
5-7 days after period ends
regularity of menstrual cycle influenced by (4)
age
physical health/fitness
psychosocial/emotional status
environment
menarche
first menstruation
puberty
transitional stage between childhood and sexual maturity
“normal” cycle average
28 days (1st day of flow to 1st day of next flow)
variation in menstrual cycles (cycle of duration and # days)
21-35 days cycle
2-6 days flow
normal blood loss during cycle
20-60 mL
3 cycles within menstrual cycle
- chemical cycle (steroidogenesis) - brain
- ovarian cycle - ovary
- endometrial cycle - endometrium
hormones within chemical style of menstruation
GnRH
FSH
LH
hormones within ovarian cycle of menstruation
estrogen
progesterone
purpose of LH
maturation and release of 1 ova (ovulation)
endometrial response to increased progesterone and estrogen from ovaries
mature, edematous, vascular and glandular secretions ready for implantation of zygote
endometrial response to no fertilization, corpus luteum regresses, decreased progesterone and estrogen
vasospasm and vasoconstriction, necrosis of tissues, sloughing (menses)
effect of HCG (human chorionic gonadotropin) on corpus luteum
keeps corpus luteum alive for 12 weeks through progesterone
indicators of ovulation
- basal body temp increases 0.5-1 degree F for 10-12 days
- cervical secretions change (increased, spinnbarkeit, ferning)
- cervical os dilation
- mittelschmerz
what is spinnbarkeit
cervical mucus stretches > 6 cm
egg white
what is ferning during ovulation
dried, crystalline pattern of cervical mucus
what is mittelschmerz during ovulation
sharp lower abdominal pain during ovulation
lifespan of corpeus luteum if HCG is not present
14 days
pituitary: primary hormone during 1st half of cycle
FSH
what hormone is critical for maintaining zygote/embryo
progesterone
pituitary: primary hormone during 2nd half of cycle
LH
ovarian: primary hormone during 1st half of cycle
follicular
- estrogen dominant
- maturation of ovarian follicle
ovarian: primary hormone during 2nd half of cycle
luteal
- progesterone dominant
- follicle after ovulation
