Lab Manual: Female Reproductive system Flashcards
(60 cards)
the bulk of the ovary is divided into the ___ and ___
cellular CORTEX and the MEDULLA made of loose connective tissue.
the ovary medulla is made of ___ ___ CT. Main cells of the medulla
loose fibrous connective tissue. main cells in the medulla are HILUS cells : produces androgens.
ovarian follicles develop within the ___
cortex.
each ovarian follicle is surrounded by a ____ made of connective tissue.
STROMA
the embryonic ovarian cortex becomes populated by ____ germ cells, which form ____ follicles
PRIMORDIAL GERM CELLS, which form PRIMORDIAL FOLLICLES.
not all the primordial follicles go onto further development. some of them die in a process called ___
atresia
inside the primordial follicles, there are ___ ___ and are suspended in ____ of meiosis 1 until they continue development just prior to ovulation
PRIMARY OOCYTES and are suspended in PROPHASE 1
primordial follicles and their primary oocytes stay in a constant state until puberty, in which they begin to develop in response to ____
FSH.
as the primary oocyte matures, follicle cells begin to form ____ cells, and they form the ____ ___ ___
as the primary oocyte matures, follicle cells begin to form GRANULOSA cells, and they form the multilaminar PRIMARY FOLLICLE.
during the formation of the primary follicle, a ___ ___ forms between primary oocyte and the granulosa cells. In the stroma, the ___ ___ and ___ __ also begin to develop
ZONA PELLUCIDA. in the stroma, the theca interna and theca externa also develop.
what is the purpose of the theca interna and granulosa cells during ovulation
produce the hormoneestrogen.
development of a primary follicle into a secondary follicle involves the formation of a space called the ___. the __ ___ also forms ontop of the granulosa cells
development of a primary follicle into a secondary follicle involves the formation of a space called the ANTRUM. the CUMULUS OOPHOROUS also forms ontop of the granulosa cells
the layer of cells surrounding the oocyte, which will be ovulated with it, is called the ___ ___
corona radiata.
the secondary follicle becomes a ____ follicle.
graafian
purpose of FSH
to simulate growth and development of the ovarian follicles
purpose of luteinizing hormong
to stimulate ovulation, and is necessary for development of the corpus luteum.
just before ovulation, the primary oocyte completes the first meiotic division to form a secondary oocyte and the ___ ___ ___
first polar body. the secondary oocyte begins the second meiotic division and stops at metaphase 2 unless fertilized.
after ovulation, under the influence of LH, follicle cells remaining in the ovary form the __ ___. which follicle cells are involved?
corpus luteum. Granulosa cells form granulosa lutein cells, which secrete progesterone theca interna cells form the theca lutein cells, which secrete estrogen precurors.
if fertilization does not occur, the corpus luteim becomes ___. what happens if fertilization of the oocyte occurs?
becomes corpus albicans. if fertilization occurs, it becomes the corpus luteum of pregnancy, and HCG causes the corpus luteum to enlarge and continue to supply estrogen and progesterone necessary to maintain the pregnancy.
three portions of the fallopian tube
1) infundibulum 2) ampulla 3) isthmus
3 layers of the uterine tubes
1) mucosa 2) muscularis 3) serosa.
two cells of the mucosa of the fallopian tube
1) ciliated cells. sweeps oocyte towards uterus 2) nonciliated secretory cells. nourishes sperm and oocyte and assists in sperm capacitation.
two layers of muscularis in the fallopian tube
1) inner circular 2) outer longitudinal. helps move the oocyte to uterus
the entire uterine tube is covered with ___
serosa
