- A. Secondary oocyte and second polar body
- B. Ovum and secondary polar body
- C. Secondary oocytes and first polar body
- D. Germ cell and first polar body
Explanation: Secondary oocyte and first polar body divide by meiosis-II to give rise to an ovum and three polar bodies in the end.
Correct answer: Ovum and secondary polar body- A. Umbilical cord
- B. Placenta
- C. Conception
- D. Pregnancy
Explanation: Placenta is a physical connection between maternal uterine wall and foetal tissue.
Correct answer: Placenta- A. Human male
- B. Human female
- C. Ovaries of females
- D. Uterus of females
Explanation: In males, meosis is not initiated until postnatal life at the onset of puberty, and the goal is to form the millions of gametes required…
Correct answer: Human male- A. Menstrual cycle
- B. Menstruation
- C. Oogenesis
- D. Gametogenesis
Explanation: Changes in whole reproductive system indicate menstrual cycle i.e. changes in uterus as well as in ovary.
Correct answer: Menstrual cycle- A. Ovulation
- B. Menstruation
- C. Follicle degeneration
- D. Follicle atresia
Explanation: When one follicle starts development rest of the follicles degenerate this is called follicle atresia.
Correct answer: Follicle atresia1066. Estrogen stimulates:
- A. Secretion of FSH
- B. Laying down of endometrium
- C. Secretion of LH
- D. Laying down of endometrium and secretion of LH
Explanation: Estrogen hormone initiate thickening of uterine wall and stimulates laying down of endometrium.
Correct answer: Laying down of endometrium and secretion of LH- A. Progesterone
- B. LH
- C. LTH
- D. Prolactin
Explanation: It is luteinizing hormone which induces rupturing of mature follicle (ovulation) and formation of corpus luteum.
Correct answer: LH- A. Placenta
- B. Corpus luteum
- C. Follicle
- D. Endometrium
Explanation: Corpus luteum is a yellow colored structure formed by the rupturing of follicle during ovulation. It secretes progestone.
Correct answer: Corpus luteum- A. 4-8 days
- B. 3-7 days
- C. 2-5 days
- D. 5-9 days
Explanation: The discharge of blood and cell debris known as menstruation. This stage usually lasts for 3 - 7 days.
Correct answer: 3-7 days- A. Spermatogensis
- B. Fertilization
- C. Menstruation
- D. Oogenesis
Explanation: Oogenesis in human females starts before birth. And is arrested at prophase I unless they achieve puberty.
Correct answer: Oogenesis- A. Luteal
- B. Secrectory
- C. Proliferative
- D. Ovulation
Explanation: Based on the explanations provided, the correct answer to the question is option C) Proliferative.
Correct answer: Proliferative1072. Which one of the following is the correct matching of the events occurring during menstrual cycle?
- A. Menstruation : Breakdown of myometrium and ovum fertilized
- B. Proliferative phase: Rapid regeneration of myometrium and maturation of Graffian follicle
- C. Ovulation : LH and FSH attain peak level and sharp fall in the secretion of progesterone
- D. Secretory phase : Development of corpus luteurn and increased secretion of progesterone
Explanation: The secretory phase is the phase of the menstrual cycle that follows ovulation.
Correct answer: Secretory phase : Development of corpus luteurn and increased secretion of progesterone- A. Staphylococcus aureus
- B. Treponema pallidum
- C. Neisseria gonorrhoea
- D. Escherichia coli
Explanation: It causes a sexually transmitted infection known as gonorrhea. Gonorrhea primarily affects the mucous membranes of the urinogenital tract…
Correct answer: Neisseria gonorrhoea- A. 30 days
- B. 27 days
- C. 28 days
- D. 29 days
Explanation: In human females, the periodic reproductive cycle is completed in approximately 28 days. This is known as the menstrual cycle.
Correct answer: 28 days- A. Menstruation starts
- B. Menstruation stops and reproductive capacity is arrested
- C. Puberty begins
- D. None of the above
Explanation: Menopause is the stage in a woman's life when her ovaries stop producing eggs.
Correct answer: Menstruation stops and reproductive capacity is arrested- A. LH
- B. Androgen
- C. FSH
- D. Progesterone
Explanation: Oral contraceptives are used to prevent pregnancy. Progesterone is primarily responsible for preventing pregnancy.

- B. 100 sperms and 50 ova
- C. 200 sperms and 50 ova
- D. 50 sperms and 100 ova
Explanation: Each secondary spermatocyte gives rise to 2 sperm and each secondary oocyte gives rise to 1 ova and 1 polar body.

- B. Three large ova and one polar body
- C. Two large ova and Two polar bodies
- D. One large ovum and 2-3 polar bodies
Explanation: During oogenesis, each primary oocyte forms 2 secondary oocytes, then one s.oocyte forms 1 ova and one polar body by meiosis and the other…
