Menstrual Cycle Flashcards
During the luteal phase, basal body temperature (increases/decreases) .
Increases
The hormone estradiol causes cervical mucus to become copious, watery, and elastic during the phase of the menstrual cycle to aid sperm movement through the cervix.
Follicular Phase
Ovulation occurs days before menses, regardless of cycle length.
14
Regression of the and the abrupt loss of estradiol and progesterone cause the endometrial lining and blood to be sloughed, which is menses.
Corpus Luteum
During the phase of the menstrual cycle, a primordial follicle develops into a graafian follicle and neighboring follicles become atretic.
Follicular Phase
If fertilization does not occur, the regresses, which is the source of estradiol and progesterone.
Corpus Luteum
During the luteal phase, hormone plays a vital role in making the endometrium receptive to implantation.
Progesterone
Follicular growth is fastest during of the follicular phase.
2nd week
The phase is the phase of the menstrual cycle during which the primordial follicles in the ovary mature to the graafian stage.
Follicular
During the follicular phase of the menstrual cycle, estradiol stimulates the growth of the .
Endometrium
The phase of the menstrual cycle occurs from day 0 until day 14.
Follicular
Moderate levels of estradiol during the follicular phase of the menstrual cycle (inhibit/stimulate) gonadotropin-releasing hormone secretion by the hypothalamus.
Inhibit
During the follicular phase, the hormone, , increases the expression of luteinizing hormone receptors on the granulosa cells in the developing follicle.
FSH
The luteal phase begins with the formation of the
Corpus Luteum
hormone is highest and most important during the first week of the follicular phase where it recruits five to seven tertiary-stage ovarian follicles for entry into the menstrual cycle.
FSH
The hormones produced by the during the luteal phase suppress production of follicle-stimulating hormone and luteinizing hormone.
Corpus Luteum
During the luteal phase, the corpus luteum produces, (3 hormones) .
ESTROGEN
INHIBIN
PROGESTERONE
The main hormone controlling the follicular phase is .
Estradiol
The (menstrual cycle phase) phase can vary in length.
Follicular
The follicular phase of the menstrual cycle is dominated by the hormone .
Estradiol
Proliferation of the endometrium slows during the phase of the menstrual cycle.
Luteal
The high levels of progesterone during the phase of the menstrual cycle stimulate secretory activity of the endometrium and increase its vascularity.
Luteal
Throughout the entire follicular phase, rising levels in the blood stimulates growth of the endometrium and myometrium of the uterus.
Estrogen
The hormone causes a decrease in the quantity of cervical mucus so that it becomes thick and nonelastic.
Progesterone
In the luteal phase, hormone is significantly higher than in other phases of the menstrual cycle.
Progesterone
Ovulation occurs as a result of estrogen-induced .
LUTEINIZING HORMONE SURGE
At ovulation, cervical mucus increases in quantity and becomes (more/less) viscous.
LESS
A burst of estradiol synthesis at the end of the follicular phase has a positive feedback effect on the secretion of follicle-stimulating hormone and luteinizing hormone, resulting in the which leads to ovulation.
LH SURGE
is the event that follows a burst of estradiol secretion and the LH surge at the end of the follicular phase of the menstrual cycle.
OVULATION
A burst of estradiol synthesis at the end of the follicular phase has a feedback effect on the secretion of follicle-stimulating hormone and luteinizing hormone, resulting in the luteinizing hormone surge.
POSITIVE
During the follicular phase, follicle-stimulating hormone induces the proliferation of in the developing follicles.
Granulosa Cells
The follicular phase is the phase of the menstrual cycle during which the in the ovary mature to the graafian stage.
Primary Follicles
During the luteal phase, vascularity and secretory activity (increase/decrease) .
INCREASE
Progesterone levels are (high/low) during the follicular phase.
LOW
The rupture of the ovarian follicle occurs at the time of .
OVULATION
At ovulation, the primary oocyte completes meiosis I to yield a(n) .
secondary oocyte
polar body
A surge of follicle stimulating hormone and luteinizing hormone causes at the end of the follicular phase of the menstrual cycle.
OVULATION
