Name the hormone produced by the ovaries.

Q. Which hormone reaches its peak during luteal phase of menstrual cycle?

1. Luteinishing hormone
2. Progesterone
3. Follicle stimulating hormone
4. Oestrogen

1. FSH, progesterone, estrogen

2. Estrogen, FSH, progesterone

3. Estrogen, progesterone, FSH

4. FSH, estrogen, progesterone

Q. In Drosophila, sex index of superfemale is

1. 1
2. 0.5
3. 1.5

Q. Fill in the blanks:
(f) The process of release of ovum from a mature follicle is called

Q. Sir/Mam can you please explain ovulation in simple terms.I have seen the video but could not understand the concepts very well.Also tried google but agaim the same thing.So i shall be grateful if you can explain in simple english.

Q. Graafian follicle of ovary secretes

1. Estrogen
2. Relaxin
3. Progesterone
4. Cortisone

Q.

The function of progesterone is

1. To prepare uterus for pregnancy

2. To maintain pregnancy

3. Implantation of embryo

4. All the above

Q.

What happens to the primary oocyte when the ovarian follicles mature?

Q. During bleeding phase of menstrual cycle, unfertilized secondary oocyte undergoes autolysis. The interplay of hormone then is:

1. Progesterone and estrogen continue the hypertropy of endometrial lining
2. Prolactin and progesterone reduces LH level causing regression of corpus luteum
3. Progesterone inhibits the release of LH from causing regression of corpus luteum
4. Prolactin and estrogen inhibits progesterone secretion leading to sloughing off of uterine lining

Q. Which hormone reaches its peak during luteal phase of menstrual cycle?

1. Luteinishing hormone
2. Progesterone
3. Follicle stimulating hormone
4. Oestrogen

Q.

What is the main hormone that helps primordial follicles to develop into mature follicle?

1. Luteinizing hormone

2. Follicle stimulating hormone

3. Human chorionic gonadotrophin

4. Estrogen

Q.

A dopamine tract from the hypothalamus plays an important role in regulating the release of prolactin. All of the following are true regarding prolactin except

1. It stimulates milk production.

2. It is produced by the anterior pituitary gland.

3. Secretion is inhibited by dopamine.

4. It is produced in the same area as oxytocin.

Q.

Which of the following statements is not true?

1. Follicles in the ovary produce estrogen

2. The largest follicle will have more FSH receptors and hence survives low levels of FSH

3. Primary follicle up to the antral stage is stimulated mainly by LH alone.

4. Heightened levels of estrogen will taper FSH production

Q. During bleeding phase of menstrual cycle
unfertilized secondary oocyte undergoes
autolysis. The interplay of hormones then is

1. prolactin and progesterone reduces LH level causing regression of corpus luteum
2. progesterone and estrogen continue the hypertrophy of endometrial lining
3. progesterone inhibits the release of LH from pituitary causing regression of corpus luteum
4. prolactin and estrogen inhibits progesterone secretion leading to sloughing off of uterine lining

Q. Match column 1 to column 2:

	Column 1		Column 2
a	FSH	1	Prepare endometrium for implantation
b	LH	2	Develops female secondary sexual characters
c	Progesterone	3	Maturation of Graafian follicle
d	Estrogen	4	Development of corpus luteum

1. a-3, b-4, c-1, d-2
2. a-4, b-3, c-2, d-1
3. a-3, b-4, c-2, d-1
4. a-3, b-1, c-2, d-4

Q. Explain the development of a secondary oocyte (ovum) in a human female from the embryonic stage upto its ovulation. Name the hormones involved in this process.

Q. Withdrawal of which of the following hormones is the immediate cause of menstruation?

1. Oestrogen
2. FSH
3. FSH-RH
4. Progesterone

Q. Hormone $A$ secretes by the anterior lobe of the pituitary, which stimulates the ovaries follicle and follicle secretes the $B$ hormone. Here $A$ and $B$ refers to:

1. $A-FSH;B-$ progesterone
2. $A-FSH;B-$ inhibin
3. $A-$ Inhibin; $B-FSH$
4. $A-FSH;B-$ estrogen

Q. FSH is a

1. Glycoprotein
2. Catecholamine
3. Polypeptide
4. Steroid

Q. During bleeding phase of menstrual cycle unfertilised secondary oocyte undergoes autolysis. The interplay of hormones then is

1. Prolactin and progesterone reduces lH level causing regression of corpus luteum
2. Progesterone and estrogen continue the hypertrophy of endometrial lining
3. Progesterone inhibits the release of LH from pituitary causing regression of corpus luteum
4. Prolactin and estrogen inhibits progesterone secretion leading to sloughing off uterine lining.
