The ovarian cycle consists of three phases: follicular (preovulatory) phase, ovulation, and luteal (postovulatory) phase, whereas the uterine cycle is divided into menstruation, proliferative (postmenstrual) phase and secretory (premenstrual) phase
What are the three stages of the uterine cycle?
The menstrual cycle has three phases: Follicular (before release of the egg) Ovulatory (egg release) Luteal (after egg release)

What are the 3 phases of uterine cycle explain what happens during each phase?
The follicular phase: The time between the first day of the period and ovulation Estrogen rises as an egg prepares to be released The proliferative phase: After the period, the uterine lining builds back up again Ovulation: The release of the egg from the ovary, mid-cycle
What is the first phase of the uterine cycle?
The first phase of the menstrual cycle is the follicular or proliferative phase It occurs from day zero to day 14 of the menstrual cycle, based on the average duration of 28 days The variability in length of the menstrual cycle occurs due to variations in the length of the follicular phase
What are the 3 differences between the ovarian and uterine cycles?
The cycle that occurs in the ovaries is the ovarian cycle whereas the cycle that occurs on the uterus is a menstrual cycle Hormone release, follicle development, maturing and release of the egg are the main events of the ovarian cycle This is the difference between ovarian cycle and menstrual cycle
What are the 4 phases of menstrual cycle 12?
The menstrual cycle often begins at puberty between the ages of 8 and 15 (average age of 12) It usually starts two years after breasts and pubic hair start to develop Phases of the menstrual cycle: There are four phases: menstruation, the follicular phase, ovulation and the luteal phase
Which of the following are phases of the uterine cycle quizlet?
The four phases of menstrual cycle are Follicular Phase, Ovulation, Luteal Phase, Menstruation
What is the first phase of menstruation quizlet?
In the pre-ovulatory phase of the menstrual cycle, the ovarian follicle will undergo a series of transformations called cumulus expansion, which is stimulated by FSH During this phase, the hormone estrogen causes the lining of the uterus to grow, or proliferate
What is the second phase of the uterine cycle called quizlet?
In the uterus, after ovulation the second phase of the uterine cycle begins and is called {secretory phase} In this second phase, the progesterone from the corpus luteum acts on the endometrial lining to become secretory in preparation for a possible implantation of a fertilized egg
What is ischemic phase?
period lasting 1 or 2 days; it coincides with constriction of the spiral arteries of the endometrium that results from decreasing secretion of estrogen and progesterone The ischemia results in shrinkage and degeneration of the endometrium
What is menstruation explain?
Menstruation, or period, is normal vaginal bleeding that occurs as part of a woman’s monthly cycle Every month, your body prepares for pregnancy If no pregnancy occurs, the uterus, or womb, sheds its lining The menstrual blood is partly blood and partly tissue from inside the uterus
What is the estrogenic phase?
Estrogen levels rise and fall twice during the menstrual cycle Estrogen levels rise during the mid-follicular phase and then drop precipitously after ovulation This is followed by a secondary rise in estrogen levels during the mid-luteal phase with a decrease at the end of the menstrual cycle
What are the 4 stages of menstrual cycle?
The menstrual cycle is complex and controlled by many different glands and the hormones that these glands produce The four phases of the menstrual cycle are menstruation, the follicular phase, ovulation and the luteal phase Common menstrual problems include heavy or painful periods and premenstrual syndrome (PMS)
What are the phases of menstrual cycle indicate the changes in the ovary and uterus?
Each cycle occurs in phases based on events in the ovary (ovarian cycle) or the uterus (uterine cycle) The ovarian cycle consists of the follicular phase, ovulation, and the luteal phase; the uterine cycle consists of the menstrual, proliferative and secretory phases
At which stage of the uterine cycle does the proliferative phase occur?
The follicular phase of the female menstrual cycle includes the maturation of ovarian follicles to prepare one of them for release during ovulation During the same period, there are concurrent changes in the endometrium, which is why the follicular phase is also known as the proliferative phase
What are the 5 stages of menstrual cycle?
The day count for menstrual cycle begins on the first day of menstruation when blood starts to come out of the vaginaPhases of Menstrual cycle Menstrual phase (From day 1 to 5) Follicular phase (From day 1 to 13) Ovulation phase (Day 14) Luteal phase (From day 15 to 28)
What is mid cycle phase?
Ovulation (Mid Cycle) Ovulation occurs when an egg is released from the ovary into the fallopian tube and commonly occurs around the middle of your cycle If you have a 28 day cycle, this means around day 14
What are the different stages of menstrual cycle class 8?
The menstrual cycle is divided into four phases: (i) Menstrual phase: It extends from 1st to 4th day of the cycle (ii) Follicular phase: When the ovary is in this phase, uterus enters in the proliferative phase (iv) Luteal phase: It corresponds with the secretory phase in uterus
What are the cycles of Class 12 phases?
Menstrual cycle involve three phases- menstrual phase, follicular phase and luteal phase Menstrual flow occurs and lasts for about 3-5 days The endometrial lining of the uterus breaks along with the blood vessels which forms a red fluid and results in menstrual flow
What is the menstrual cycle class 8?
The menstrual cycle is the regular natural change that occurs in the female reproductive system(specifically the uterus and ovaries) that makes pregnancy possible [1][2] The cycle is required for the production of oocytes, and for the preparation of the uterus for pregnancy
What is the uterine cycle quizlet?
what are the 3 phases in menstrual cycle menstrual phase (days 1-5) proliferative phase (days 6-14) secretory phase (days 15-28)
Which of the following phases occurs first during the ovarian cycle?
The first half of the ovarian cycle is the follicular phase shown in Figure 1 Slowly rising levels of FSH and LH cause the growth of follicles on the surface of the ovary This process prepares the egg for ovulation As the follicles grow, they begin releasing estrogens and a low level of progesterone
What does luteal phase mean?
The luteal phase is one stage of your menstrual cycle It occurs after ovulation (when your ovaries release an egg) and before your period starts During this time, the lining of your uterus normally gets thicker to prepare for a possible pregnancy
