female reproductive system Flashcards
what sre the 5 major organs in the female reporductive system
ovaries
fallopian tubes
uterus
vagina
external genitalia - vulva
what are the three main functions of the ovaries
secrete inhibin to regulate fsh
secrete oestrogen and progesterone
produce gametes (ooctyes)
anatomy of ovaries
fallopian tube
what are infundibulum in the fallopian tube
epanded funnel shape
what are fimbriae in the fallopian tube
finger like projections
ciliated to support transport of oocytes
what are the fallopian tubes lined with
peg and mucin secreting cells
secretion complete capacitation and supply nutrients to the pre embryo
what are the two main functions of the uterus
protect abd nourish the embryo/foetus
facilliate birth by muscle contraction
what are the 3 parts of the uterus
fundus
body
cervix
where does the fundus sit
superiorly to the uterine tubes
where is the isthmus in the uterus
starts as the uterus narrows towards the base
structure of the cervix uterus
what are the three layers of the uterine wall
endometrium
myometrium
perimetrium
what does the endomterium divide into
a. superficial funtional zone - repsonds to sex hormones
b. deeper basilar zone - remains unchanged
what os the endometrium made of
epithelial cells
uterine glands
what is the myometrium
adjacent to the basiler zone of the endometrium
mass of smooth muscle that contracts during labour
whats the perimetrium
outermost layer of the uterine wall
layer of visceral peritoneum
what are the three main fucnions of the vagina
Elimination of menstrual waste
Receives semen during intercourse
Forms the lower part of the birth canal
why is acidic cervical mucus secreted by cervical glands
kill pathogens
vagina anatomy
what are Bulbospongiosus muscles
tehy extend along either side of the vaginal entrance
when contracted they decrease the diamter of the vaginal passage
external genitalia - vulva anatomy
oogenesis
produces an oocyte
longer period of time
what are oogonia and when do they complete mitotic division
female reproductive stem cells
complete mitotic divion before birth
what happens at prophase 1 in oogenesis
primary oocytes are suspended but most die before puberty
