Q. If mammalian ovum fails to get fertilised, which one of the following is unlikely?

1. Corpus luteum will disintegrate
2. Oestrogen secretion further decreases
3. Primary follicle starts developing
4. Progesterone secretion rapidly declines

Q.

Menstrual cycle is the shedding of _________.

1. Endometrium

2. Myometrium

3. Perimetrium

4. All of the above

Q.

The phase in the menstrual cycle in which the remnant of follicle in the ovary turns to corpus luteum.

Q. Which one of the following is the most likely root cause why menstruation is not taking place in regularly cycling human female?

1. Retention of well-developed corpus luteum
2. Fertilization of the ovum
3. Maintenance of the hypertrophical endometrial lining

Q.

Ovulation occurs

1. at the beginning of the menstrual cycle

2. in the mid of the menstrual cycle

3. at the end of the menstrual cycle

4. during any time of the menstrual cycle

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

1. Menstruation $\times$ Breakdown of myometrium and ovum not fertilized
2. Ovulation $\times$ LH and FSH attain peak level and sharp fall in the secretion of progesterone
3. Proliferative phase $\times$ Rapid regeneration of myometrium and maturation of Graafian follicle
4. Development of corpus $\times$ Secretory phase and increased secretion of progesterone luteum

Q. If mammalian ovum fails to get fertilised, which one of the following is unlikely?

1. Corpus luteum will disintegrate
2. Oestrogen secretion further decreases
3. Primary follicle starts developing
4. Progesterone secretion rapidly declines
