decidual reaction
progesterone
epiblast
invasion
none of the above
has a single layer of trophoblast at the
embryonic pole has an amniotic cavity is attached to the endometrial epithelium is surrounded by a degenerating zona
pellucida is called the hypoblast
FSH GnRH estradiol or estrogen progesterone all of the above
homunculi mitotic figures centrioles nucleoli pronuclei
inner cell mass hypoblast trophoblast blastocyst all of the above
FSH binds to the corpus luteum and
stimulates estrogen production FSH binds to granulosa cells of the follicle
and stimulates estrogen production FSH binds to the corpus luteum and
stimulate progesterone production FSH binds to granulosa cells of the follicle
and stimulates progesterone production FSH binds to granulosa cells of the follicle
and stimulates LH production
acts on the hypothalamus, causing release of
FSH & LH is released once a month from the corpus
luteum acts on anterior pituitary gland, causing
release of FSH & LH acts on the anterior pituitary causing release
of estrogen and progesterone is one of those meaningless substances that
scientists play with in lieu of working for a
living
results in ovulation triggers resumption of meiosis within the
oocyte is caused by a positive feedback effect of
estrogen all of the above none of the above
high circulating levels of FSH and LH high circulating levels of progesterone an extreme variation in length from cycle to
cycle a thin, non-vascularized endometrium none of the above
is released upon stimulation of the follicle by
FSH is released as a result of the LH surge is released after fertilization is released after pronuclear formation is also known as the south pole
is only functional during the follicular phase
of the menstrual cycle has receptors for progesterone and estrogen is rescued from decline by hCG secreted by
the implanted embryo produces both FSH and LH none of the above
implants in the endometrium usually attaches to endometrial epithelium at
its embryonic pole usually implants in the posterior wall of the
body of the uterus causes change in the endometrial tissues all of the above are correct
is caused by the zona pellucida occurs in the male prevents polyspermy is essential for fertilization removes the head of the sperm
sperm flagellum (tail) vaginal cilia an intact zona pellucida smooth muscle contractions gravity
formation of a hollow ball of cells formation of the zona pellucida increase in the size of the cells in the zygote increase in the number of cells in the zygote none of the above
internal os of the uterus mesentery ovary uterine tube other
tight junctions appear between peripheral
cells, isolating the inner cells from uterine
fluid the location of the cells dictates their fate the outer cells pump fluid, creating a fluid-
filled blastocoele attachment to the uterine epithelium has
not yet occurred all of the above are correct
tail body neck acrosome nucleus
pellucida limitans orbicularis corona oophorus
true false
the cell membrane is removed from the
spermatozoan head the zona pellucida must be shed the acrosomal membrane must perforate the tailpiece is lost the decidua reaction must occur
the haploid number of chromosomes is
restored the chromosomal sex is determined cleavage is inhibited the inner cell mass becomes recognizable the ovum becomes the blastocyst
interaction between uterine endometrium
and hypoblast release of proteolytic enzymes loss of the decidua acrosome reaction capacitation
the placenta overbridges the internal os of
the uterus implantation is inside the uterus severe bleeding is present during vaginal
delivery the most common site is the uterine tube
5 50 100 200 more than 200
upper third of the uterine tube middle third of the uterine tube lower third of the uterine tube uterus cervix
ovulation gametogenesis histogenesis morphogenesis none of the above
meiotic mitotic amniotic anucleotic by binary fission
2-cell stage morula blastocyst implanting embryo all of the above
ovary abdomen uterine tube cervix posterior wall of the uterus
primary oocyte zygote morula very early blastocyst all of the above are correct
inner cell mass embryonic hypoblast epiblast primitive streak amnion
syncytiotrophoblast blastocyst cavity notochord somitomeres
onset of last menstruation last sexual intercourse last full moon last missed menstrual period onset of breast changes
zygote morula blastocyst trophoblast syncytiotrophoblast
cytotrophoblast
blastocoele
inner cell mass
blastomere
embryoblast
zona pellucida
Sperm do not contain mitochondria Head and tail of sperm degrade upon fertilization Cell division process leaves out mitochondria DNA from sperm Mitochondrial DNA of sperm is degraded upon entering egg
Placenta / embryo and fetus Embryo and fetus / placenta Chorionic membrane / amniotic membrane Amniotic membrane / chorionic membrane
Posterior superior wall of uterus Anterior posterior wall of uterus Lateral superior wall of uterus Medial posterior wall of uterus Ampulla of uterine tube
Zona pellucida / corona radiata Cytotrophoblast / syncytiotrophoblast Endoderm / ectoderm Ectoderm/ mesoderm Blastocyst / embryoblast
