Menstrual flow occurs due to shedding off

Hormones for the menstrual cycle are produced by

1. $\left(\mathrm{i}\right)\to \left(\mathrm{a}\right),\left(\mathrm{ii}\right)\to \left(\mathrm{c}\right),\left(\mathrm{iii}\right)\to \left(\mathrm{b}\right),\left(\mathrm{iv}\right)\to \left(\mathrm{d}\right)$

2. $\left(\mathrm{i}\right)\to \left(\mathrm{c}\right),\left(\mathrm{ii}\right)\to \left(\mathrm{d}\right),\left(\mathrm{iii}\right)\to \left(\mathrm{b}\right),\left(\mathrm{iv}\right)\to \left(\mathrm{a}\right)$

3. $\left(\mathrm{i}\right)\to \left(\mathrm{c}\right),\left(\mathrm{ii}\right)\to \left(\mathrm{b}\right),\left(\mathrm{iii}\right)\to \left(\mathrm{d}\right),\left(\mathrm{iv}\right)\to \left(\mathrm{a}\right)$

4. $\left(\mathrm{i}\right)\to \left(\mathrm{c}\right),\left(\mathrm{ii}\right)\to \left(\mathrm{a}\right),\left(\mathrm{iii}\right)\to \left(\mathrm{d}\right),\left(\mathrm{iv}\right)\to \left(\mathrm{b}\right)$

1. FSH           Progesterone          LH              Oestrogen

The menstrual cycle begins with the casting off of

Which of the following events is not associated with ovulation in human female?

1. Decrease in oestradiol

2. Full development of Graafian follicle

3. Release of secondary oocyte

4. LH surge

Which event is incorrectly matched with the time of its occurence [with respect to a 28 days menstrual cycle]?

1. Beginning of the menstrual flow - Day 1

2. Ovulation - Day 14

3. Beginning of the proliferative phase - Day 5

4. Peak  secretion of estrogen - Day 22

The correct sequence of the various phases of a typical menstrual cycle is:

1. Menstrual → Follicular → secretory → Ovulatory

2. Menstrual → Follicular → Ovulatory → secretory

3. Ovulatory → Follicular → secretory → Menstrual

4. Menstrual → secretory → Follicular → Ovulatory
