histology of uterus Flashcards
role of ovaries
-produce gametes
-produce steroids, mainly oestrogens and progestogens
what is found in the ovaries medulla
The medulla forms the core of the organ and contains loose connective tissue, contorted arteries, veins and lymphatics, and is continuous with the hilum of the organ
cortex of the ovary
has scattered ovarian follicles in a highly cellular connective tissue stroma
label
what is oogenesis
development of oocytes, the female germ cells, from oogonia
what is folliculogenesis
growth of the follicle, which consists of the oocyte and any associated support cells
formation of the follicle
what are primary follicles defined by
cuboidal granulosa cells
-zona granulosa
what do the secretory cells of the uterine tubes secrete
nutrients
where does fertilization occur
in the ampulla
what happens to the follicle after ovulation
follicle transforms into a corpus luteum with the theca and granulosa cells secreting oestrogens and progesterone, which helps prepare the uterus for implantation.
what is the wall of the uterus made up of
-inner secretory mucosa called the endometrium
-myometrium (coat of 3 layers of smooth muscle)
-perimetrium (outer visceral covering of loose connective tissue)
what is the endometrium of the uterus divided into
-stratum functionalis
-stratum basalis
what happens to uterus in the menstrual phase
arterioles in the stratum functionalis undergo constriction, depriving the tissue of blood and causing ischemia, with resultant tissue breakdown, leakage of blood and tissue sloughing.
what happens to uterus in the secretory phase
the glands become coiled with a corkscrew appearance and secrete glycogen.
what is this
external genitalia
