N1H_Vivares, Justin_Reproductive System Flashcards
This set of flashcards provides a concise overview of the reproductive system, particularly focusing on the female reproductive system.
What is the remaining follicular mass called, after an egg is ovulated?
corpus luteum
It is the hormone which causes the myoepithelial cells to contract?
oxytocin
What happens to the ruptured follicle, after ovulation?
It becomes a corpus luteum
What is the crown-to-bump length of an 8-week human embryo?
22 mm
Where does organogenesis occurs, during human embryonic development?
during the first trimester
It is the outer layer of the blastocyst, which attaches to the uterine wall.
trophoblast
Where does successful fertilization of the egg occurs?
Ampulla or Ampulla of the uterine tube
These are the primary reproductive that produces ova.
Ovaries
A follicle that is mature and will leave the ovary during ovulation.
Vesicular follicle or Graafian follicle
Parts of the female reproductive system, which makes-up the female duct system.
Uterine tubes, uterus, and vagina
It receives, retains, and nurtures the fertilized egg and also participates in childbirth
Uterus
These are not physically connected to the ovaries, but have fimbriae on their distal ends to “wave” the egg inside after ovulation.
Uterine tubes or fallopian tubes
It is the female copulatory organ
and the birth canal; it is partially closed by the
hymen, though a variety of activities can cause it
to rupture
vagina
It is the production of eggs; it begins with stem cells (oogonia) that produce primary
oocytes.
Oogenesis
What is the main female sex hormone that n drives the ovarian cycle and stimulates
secondary sex characteristics, such as breast development, growth of axillary and pubic hair, increased fat deposits, widening and lightening of the pelvis, and menses.
Estrogen
This cycle ) includes
cyclic changes to the endometrium of the uterus in response to changing ovarian hormone levels
in the blood.
uterine cycle or menstrual cycle
The phase of uterine cycle, when the endometrium begins to regenerate, glands form in it, and blood supply increases.
Proliferative phase
The phase of uterine cycle, when increasing progesterone levels stimulate more endometrial gland
secretions and further development of blood
supply.
Secretory phase
The phase of uterine cycle, when the endometrial lining
is shed.
Menstrual phase
What degenerates, as LH levels naturally begin to decline, if no fertilization has occurred, causing progesterone levels to decline?
corpus luteum
What causes the shedding of the endometrial lining in the uterus?
low ovarian hormone levels
How many hours does the egg is viable, after ovulation?
12 to 24 hours
It is called the early, rapid mitotic divisions of the zygote; this provides large cell numbers
for development to continue.
cleavage
It is a ball of about 100 cells with a hollow center and begins secreting human chorionic gonadotropin (hCG), which prompts the corpus luteum to continue producing progesterone to maintain the pregnancy.
blastocyst
