Cycles occur all over biology and this is a good example of a question where you should be able to mention an extensive range of subjects. I would aim to include the following: 1. The cell cycle including G1 (in which some organelles are replicated), S phase (in which DNA is replicated) and G2 then mitosis.
Male topics and female topics with colour sightlessness, ocular defects, irregular menstruations, gynaecological jobs, Premenstrual Syndrome, any hormonal intervention, other medicine, sleep upsets and manus malformations were screened and excluded from the survey. All topics were instructed to daily chart their basal organic structure temperature during the full survey period.

There are embedded videos in the PPT file itself, there are animations that also very clearly explain the basics and the details of the menstrual cycle. Some formative assessments built in, ie. matching, True False, and a sample exam question at the end with answers. Appropriate for GCSE, iGCSE, A Level, IB.
The menstrual cycle: FSH is secreted by the pituitary gland and its levels start to rise. This stimulates the follicle to develop and the follicle cells to secret estrogen. Estrogen then causes the follicle cells to make more FSH receptors so that these can respond more strongly to the FSH.
Estrogen and progesterone cause pre-natal development of female reproductive organs and female secondary sexual characteristics during puberty. The menstrual cycle is controlled by negative and positive feedback mechanisms involving ovarian and pituitary hormones.
Explain the roles of specific hormones in the menstrual cycle, including positive and negative feedback mechanisms. Accurate transmission of base sequences to offspring depends on successful gamete production. Describe how spermatogenesis occurs in humans.
The menstrual flow consists of secretion of endometrial glands, cell debris, unfertilized ovum. After 4 th day, once again the FSH secretion from the pituitary is resumed and the new follicle starts developing. (ii) Follicular phase: When the ovary is in this phase, the uterus enters in the proliferative phase.

(Wikipedia) The menstrual cycle is a complex cycle and is controlled by hormones produced by.
This quiz was compiled from questions from past IB Biology International exams. My intention in creating it is to give students the opportunity to practice the real exam as a mock test. When you finish this, you'll have an idea of how you'll do on the real exam, and whether or not you might need to study more. Good luck! P.S.: Not every question has a picture.
The menstrual cycle is a recurring process which takes around 28 days. During the process, the lining of the uterus is prepared for pregnancy. If implantation of the fertilised egg into the uterus.
