Medical Terminology 6 Flashcards
Gyn reproductive system
What is the function of the gyn reproductive system
to produce and transport ova
discharge unfertilized ova
nourish the fetus through pregnancy
develop breasts to feed baby
main components
ovaries
fallopian tubes
uterus
vagina
vulva
mammary glands
external genitalia
(vulva) sex or reproductive organs visible on the outside of the body
gestation
length of time from conception to birth
lactation
production and release of milk by mammary glands
orifice
mouth, entrance or outlet of any anatomical structure
cornu
corners of fundus (where the adnexa attach to the uterus)
fundus
upper, broad aspect
corpus (body)
body of uterus -includes endometrial cavity
lower uterine segment
lower aspect of endometrial cavity near junction with endocervix
cervix
constricted portion of the uterus opening into the vagina
ovaries
produce gametes (oogenesis) and steroid hormone production (steroidogenesis)
oogenesis
production of gametes
steroidogenesis
steroid hormone production
estrogen
promote growth/ maturation of internal and external sex organ - signals mammary glands to promote breast development during gestation
progestrogens
prepare internal sex organs for pregnancy
cortex
follicules in a cellular connective tissue-smooth muscle stroma around the follicules (periphery)
medulla
central portion of the ovary - mass of contorted vessels and nerves with loose connective tissue
surface of ovaries
covered by germinal epithelium
tunica albuginea
underlines germinal epithelium adjacent to cortex
fallopian tubes
transport ovum from ovary to uterus for envt of fertilization
infundibulum
near the fimbriated end, toward ovary
ampulla
longest segment 2/3 of length of fallopian tube
isthmus
narrow medical segment, within the gyn system this the area connecting the fallopian tube and uterus
uterine/ intramural
within the uterine wall - opens into uterine cavity
menstrual cycle Days 1-5
“menstrual” uterine endometrium sloughs off with hormones stimulation
menstrual cycle Days 6-14
“ovulatory” endometrium begins to thicken as new tissue is rebuild - ova begin to mature in graafian follicles, one reaching full maturity - day 14 follicule ruptures
menstrual cycle Days 15- 28
“postovulatry” empty follicle fills w yellow material -corpus luteum- secreations of estrogen/progestorone stimulating the building of endometrium
mammary glands
secretes milk for the nourishment of newborns-lactation
estrogen
stimulates formation of adipose tissue
areola
contains sebaceous glands sweat glands and modified mammary glands for protection, lubrication and dicouraging microbial growth
breast cancer risk factors
hormonal exposure and genetic predisposition
prognostic factors for breast cancer
size
tumor type
grade
spread?
hormone receptor status
gene signitures
ER
estrogen receptors
PR
progesterone receptor
Her2
receptor for breast
mutations associated with breast cancer
BRCA1 BRCA2 TP53
dilation in relation to labor and delivery
uterine contraction
expulsion- labor and delivery
time from complete dilation to birth
