  4. LH only
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Progesterone is a hormone which is secreted by the corpus luteum. It is responsible for the maintenance of the endometrium of the uterus. As long as the progesterone is secreted by the corpus luteum, the menses does not begin. When the corpus luteum degenerates in the absence of a fertilization event, the progesterone secretion stops and the endometrium starts to break down and menses begin. So, in order to delay the menses, intake of progesterone will be advised because it will prevent the break down of endometrium and menses will not occur.

A. FSH is responsible for the follicular growth in ovarian cells. It is secreted by the pituitary gland.
B. Oestrogen is responsible for synergistic effect with FSH during the menstrual cycle.
C. Progesterone is the endometrium maintaining hormone, so it is also called the pregnancy hormone.
D. LH is secreted by the pituitary gland and it is responsible for the ovulation.
Hence, the correct answer is 'Progesterone only'

B Correct answer
Explanation

The release of the first menstrual flow or period is called menarche. It marks the beginning of a female's reproductive life and is one of the most obvious signals of the onset of puberty. Menarche usually occurs between the age of 11-14 years. While Menopause is the condition in which menstrual cycle stops naturally in women. 


So the answer is false and the statement should be"menopause is the permanent stoppage of menstruation in females".

The time for optimum chances of conception in a woman is starting from the day of menstruation.

  1. 1st day

  2. 4th day

  3. 14th day

  4. 26th day
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

This is usually about 14 days after the first day of your last period if your cycle is around 28 days long. An egg lives for about 12-24 hours after being released. For pregnancy to happen, the egg must be fertilized by sperm within this time. Sperm can live for up to 7 days inside a woman's body.


So, the correct option is 'Option C, 14th day'.

Which of the following statement is incorrect?

  1. First menstruation at puberty is menarche

  2. Release of ovum from ovary is oogenesis

  3. Menstruation is repeated at an average interval of about 28-29 days

  4. Lack of menstruation may be indicative of pregnancy

B Correct answer
Explanation

The release of an ovum from the ovary is called ovulation, not oogenesis. Oogenesis is the broader process of formation of female gametes.

Which one of the following is the correct matching of the events occurring during menstrual cycle?

  1. Proliferative phase: Rapid regeneration of myometrium and maturation of Graafian follicle

  2. Development of: Secretory phase corpus luteum and increased secretion of progesterone

  3. Menstruation: Breakdown of myometrium and ovum not fertilised

  4. Ovulation: LH and FSH attain peak level and sharp fall in the secretion of progesterone

Menstruation occurs in order to

  1. To shed blood

  2. To shed enlarged endometrium layer which is not needed

  3. To shed ovum

  4. To help entry of sperm
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Menstruation is a woman's monthly bleeding. It occurs so as to shed the lining of the uterus or womb.
In menstrual cycle, the uterus gets prepared for implantation and the endometrium builds up, After ovulation, if the egg released does not gets implanted in the uterus, it leads to shedding off this endometrium and its lining and this is called as menstruation,
Thus, the correct answer is option B.

The phase of menstrual cycle in humans, that lasts for 3 - 5 days is 

  1. Follicular phase

  2. Ovulatory phase

  3. Luteal phase

  4. Menstruation
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

The rhythmic reproductive cycle in the female primates is called as the menstrual cycle. The first menstruation begins at puberty and is called as menarche and is repeated at an average interval of about 28 / 29 days.

The major phases of the menstrual cycle are- menstrual phase, follicular phase and luteal phase. The cycle starts with the menstrual phase, when menstrual flow occurs and it lasts for 3-5 days. The menstrual flow results due to breakdown of endometrial lining of the uterus and its blood vessels, which forms liquid, that comes out through vagina. Menstruation only occurs if the released ovum is not fertilised. Lack of menstruation may be indicative of pregnancy. Thus, the correct answer is option D.

C Correct answer
Explanation

The reproductive cycle in the female primates is called menstrual cycle. The first menstruation begins at puberty and is called as menarche. In human females, menstruation is repeated at an interval of about 28/29 days, and the cycle of events starting from one menstruation till the next one is called as the menstrual cycle. In human beings, menstrual cycle ceases around 50 years of age; that is termed as menopause.

The reproductive cycle in the female primates (e.g., monkeys, apes and human beings) is called as menstrual cycle. The first menstruation begins at puberty and is called as menarche. In human females, menstruation is repeated at an average interval of about 28/29 days, and the cycle of events starting from one menstruation till the next one is called as the menstrual cycle. One ovum is released (ovulation) during the middle of each menstrual cycle.

Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

All the statements above are correct except the last one. Menstrual blood normally does not clots and flows through cervix and vagina along with inner lining of uterus. But it may clot also especially if there is blockage in cervix and free flow is obstructed. The menstrual blood contains not only blood but also tissue from the lining of the uterus. Clots are a natural way of controlling bleeding. Scientifically, it is a complicated and involved process that leads to fibrin being formed into a matrix. 
On the exposed parts of body like scraped knee, this mechanism leads to scab formation. But inside the uterus, the process results in a clot. Because blood in the uterus is mixed with many other cells and endometrial tissue, there is a difference between this clot and those seen on the skin. Whenever blood pools or is retained inside the uterus it is likely to clot. When menstrual blood and cells pass immediately outside the body, clots are less likely. As a general rule, the redder the blood is, the faster it has reached the outside. The blacker it is, the longer it took to exit the body. If the blood is accumulating faster than the body's ability to transfer it out of the uterus, clots are the result. Many women routinely have some clotting during menses. Factors that determine whether clots will occur include: the size of the uterus, the ability of the uterine myometrium (muscle) to contract, fibroids, adenomyosis, the diameter of the cervical canal through which the blood must flow, any obstruction to the outflow of menstrual products such as polyps, adhesions, etc.
