What are the four phases of the uterine cycle?
They mainly include:
- A pair of ovaries that store, nourish and release ova.
- Uterus (womb), where implantation of a fertilised egg takes place and the foetus develops.
- Pair of the fallopian tubes connecting the ovaries and uterus.

Are the uterine and ovarian cycles the same?
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.

How do the ovarian and uterine cycles work together to make it possible for reproduction?
The ovaries produce the egg cells, called the ova or oocytes. The oocytes are then transported to the fallopian tube where fertilization by a sperm may occur. The fertilized egg then moves to the uterus, where the uterine lining has thickened in response to the normal hormones of the reproductive cycle.
What are the major events of the uterine and ovarian cycles?
The ovarian cycle may be divided into three stages: the follicular phase, ovulation, and the luteal phase.

What are the 3 differences between the ovarian and uterine cycles?
Summary – Ovarian Cycle vs Menstrual Cycle Hormone release, follicle development, maturing and release of the egg are the main events of the ovarian cycle. Menstruation, the growth of uterine wall and cut off the blood and nutrient supply to the uterine wall are the main events of the menstrual cycle.
What hormone controls the ovarian and uterine cycle?
The hormone responsible for these changes is progesterone, which is manufactured by the corpus luteum. Under the influence of progesterone, the uterus begins to create a highly vascularized bed for a fertilized egg.
Which of the two events occur simultaneously in follicular phase?
The follicular phase follows the menstrual phase. During this phase, the primary follicles in the ovary grow to become a fully mature Graafian follicle and simultaneously th endometrium of uterus regenerates through proliferation.
At which stage of the uterine cycle does the menstrual cycle occur?
Question 14 Explanation: The menstrual phase occurs at the very beginning of the uterine cycle. It only occurs if no ovum is fertilised. The process begins with the breakdown of the corpus luteum which therefore ceases to produce progesterone.
What are the two female reproductive cycles?
A fertile female exhibits two periodic cycles: the ovarian cycle, which occurs in the cortex of the ovary and the menstrual cycle that happens in the endometrium of the uterus.

How do the uterine and ovarian cycles overlap quizlet?
These two cycles overlap because the menstrual cycle is preparing the uterus to carry the egg while the ovarian cycle is prepping the oocyte for fertilization. They both work on a 28 day cycle.
What is happening in the uterine cycle if ovarian cycle is at ovulation?
During ovulation, the egg bursts from its follicle, but the ruptured follicle stays on the surface of the ovary. For the next two weeks or so, the follicle transforms into a structure known as the corpus luteum. This structure starts releasing progesterone, along with small amounts of oestrogen.
What is the uterine cycle?
The uterine cycle includes the increase in the endometrium in preparation for implantation and the shedding of the lining following lack of implantation, termed menstruation. Menstrual cycles are counted from the first day of menstrual bleeding.
What hormone controls the ovarian and uterine cycles?
The hormone responsible for these changes is progesterone, which is manufactured by the corpus luteum. Under the influence of progesterone, the uterus begins to create a highly vascularized bed for a fertilized egg. If a pregnancy occurs, the corpus luteum produces progesterone until about 10 weeks gestation.
How long are the typical ovarian and uterine cycles in a female quizlet?
The average length of the cycle is 28 days and the normal range is from 24 – 35 days. This is controlled by the pituitary hormones. Controlled by the ovarian hormones which is produced in the ovaries.
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 uterine changes during menstrual cycle?
While the ovaries are working on developing the egg-containing follicles, the uterus is responding to the estrogen produced by the follicles, rebuilding the lining that was just shed during the last period. This is called the proliferative phase because the endometrium (the lining of the uterus) becomes thicker.
What Are the Ovarian and Uterine Cycle?
Two cycles are engaged with the guideline of a lady's richness: the ovarian cycle and the uterine cycle (additionally called the period). The ovarian cycle is a cycle that controls a lady's fruitfulness. The ovary of the follicle that produces an egg every month addresses the ovarian cycle.
Ovulation
Ovulation is the stage in a follicular phase where a developed ovarian or ovary follicle bursts, a primary oocyte. It releases an ovum (otherwise called an oocyte, female gamete, or egg). Ovulation also happens in the estrous pattern of other female vertebrates/ theca, which contrasts from numerous views from the monthly cycle.
The Luteal Phase
The menstrual cycle's luteal phase (or secretory stage) is the last piece of the feminine or estrous cycle. It starts with the arrangement of the corpus luteum and finishes in one or the other pregnancy or luteolysis in the uterine lining when the egg gets ovulate.
Uterine Cycle
The life systems of the uterus and formation of menstrual cycle/ menses:
Proliferative Stage
During the monthly cycle, levels of estradiol (an estrogen) differ by 200%. Hormonal changes shift by more than 1200 percent.
Secretory Phase
The secretory phase is the uterine lining's final stage, which corresponds to the luteal stage of the ovarian cycle. The corpus luteum releases progesterone during the secretory period, which plays an important role in preparing the endometrium for blastocyst implantation (a treated egg, which has started to grow).
What is Menstrual Cycle?
Menstrual cycle is the cycle that occurs in the uterus. It is also a cycle that takes place monthly with an average duration of 28 days. Uterine wall prepares for the possibility of an egg to be fertilized and settle in the uterus.
What is the Difference Between Ovarian Cycle and Menstrual Cycle?
Ovarian cycle occurs in the ovaries whereas menstrual cycle occurs in the uterus. During the ovarian cycle, several events occur such as hormone release, follicle development and ovulation. On the other hand, during the menstrual cycle, the growth of the endometrial tissue, blood supply to the tissue and the cut off when implantation does not occur, and the shed of the developed tissues occur.
What are the main events of the ovarian cycle?
Hormone release, follicle development, maturing and release of the egg are the main events of the ovarian cycle. Menstruation, the growth of uterine wall and cut off the blood and nutrient supply to the uterine wall are the main events of the menstrual cycle. Both cycles prepare a woman for a pregnancy, but both cycles stop when ...
How many days does the ovarian cycle last?
This cycle governs by the combinational and sequential actions of several hormones including FSH, LH, progesterone, androgen, estradiol, and insulin. There are three phases in the ovarian cycle that run several days per cycle. They are a follicular phase (12 to 14 days), periovulatory phase (3 days) and luteal phase (14 to 16 days).
What are the two cycles of a woman?
Ovarian cycle and menstrual cycle are two cycles occurring in women. These two cycles prepare a woman to conceive and give birth to an offspring and become a mother. Both cycles occur in the female reproductive system. Thus, they are hormone responsive cycles. Females undergo these two cycles from puberty to menopause.
What are the two phases of the menstrual cycle?
The other two phases of the menstrual cycle are a proliferative phase and the secretory phase. When the one cycle completes, the next cycle starts. This cycle is driven by the hormones produced from the ovarian cycle.
How long is the ovarian cycle?
The average length of the ovarian cycle is approximately 27 – 29 days in a healthy woman. However, it can range from 23 to 34 days.
What happens to the corpus luteum after fertilization?
At this point, FSH and LH levels drop quickly. If fertilization does not occur, then the corpus luteum degenerates. If fertilization does occur, hormones associated with pregnancy maintain the corpus luteum. The ovarian and uterine cycles are controlled by several hormones. The ovarian cycle is dominated by the estrogen hormones, ...
What is the first phase of the ovarian cycle?
The first phase of the ovarian cycle, known as the follicular phase , produces a dominant follicle and ends in ovulation. More specifically, the ovarian cycle begins with a rise in FSH levels, causing a small group of primary follicles (small follicles containing primary oocytes—diploid cells that will eventually give rise to a mature ovum) to begin to grow. Approximately 10 of these Graafian follicles begin to mature, until all but one die, leaving a single Graafian follicle, which is the preovulatory follicle. At this point, levels of estradiol drop and levels of LH rise. High levels of LH cause the follicle to rupture, releasing the egg from the ovary. This process is called ovulation. The follicular phase is about 14 days long.
What is the role of follicles in the ovarian cycle?
The first phase of the ovarian cycle, known as the follicular phase, produces a dominant follicle and ends in ovulation. More specifically, the ovarian cycle begins with a rise in FSH levels, causing a small group ...
What hormones are released during the ovarian cycle?
The action of gonadotropin-releasing hormone (GnRH) induces the release of other hormones, including follicle-stimulating hormone (FSH) and luteinizing hormone (LH) from the pituitary gland and the estrogen hormones (the main hormone of which is estradiol) ...
What is the uterine cycle?
The uterine cycle represents a sequence of changes in the uterine lining (endometrium) in response to ovarian hormones. Phases include menstruation, rebuilding of the endometrium, and preparation for implantation of an embryo. The ovarian and uterine cycles are controlled by changes in hormone levels. The action of gonadotropin-releasing hormone ...
What hormones regulate the uterine cycle?
Luteinizing hormone (LH), follicle-stimulating hormone (FSH), progesterone, and estradiol fluctuate to regulate the ovarian and uterine cycles. There are two cycles involved in the regulation of a woman's fertility: the ovarian cycle and the uterine cycle (also called the menstrual cycle).
How long is the average ovarian cycle?
FSH and LH also play key roles in the ovarian cycle. The average cycle is 28 days, but normal cycle length varies among women. The decline of progesterone toward the end of the ovarian cycle triggers the beginning of the uterine (menstrual) cycle.
