Definition

The menstrual cycle is the monthly series of changes in the female reproductive system that prepares the body for pregnancy.

Example

If no fertilisation occurs, the thickened uterine lining breaks down and comes out through the vagina as menstruation.

Rule to remember

Menstrual cycle prepares the reproductive system for pregnancy; if fertilisation does not occur, menstruation follows.

Memory hook

Cycle prepares, menstruation clears.

Examples and method

Worked example

If a girl has no fertilisation after ovulation, the uterus does not need the thick lining and it is shed. This is why menstruation occurs at the end of that cycle.

Method to apply

1. Note whether the question is about the monthly cycle. 2. Check if it refers to preparation of uterus and egg release. 3. If fertilisation does not happen, the lining is shed. 4. Use the terms menstruation and menstrual cycle correctly.

Diagram support

A cycle diagram with ovary, uterus, egg release, and menstruation stages is very helpful.

How CBSE asks it

Questions may ask for the role of the menstrual cycle, the difference between menstruation and the full cycle, or the condition under which menstruation occurs.

Avoid common mistakes

Common confusion

Students often think menstruation is the same as the entire menstrual cycle. Menstruation is only one part of the full cycle.

Common wrong answer

A common wrong answer is to say menstruation is the whole cycle. That is wrong because menstruation is only one stage of the cycle.

Exam tip

Remember the cycle as preparation, release, possible fertilisation, and shedding if pregnancy does not occur.

Quick check

If fertilisation does not happen, which part of the uterine lining is removed from the body?

The thickened uterine lining is shed from the body as menstruation. This is one part of the menstrual cycle when pregnancy has not occurred.
