Reproduction And Development
Overview
Human reproduction is a chain of precisely timed events: two specialised cells fuse, a single fertilised cell divides to build an entire embryo, and a set of hormones choreographs everything from the monthly cycle that makes fertilisation possible to the process of birth itself. This lesson sets out that chain accurately and in the correct anatomical and clinical language.
You will learn the structure of the male and female reproductive systems, how meiosis produces gametes, the hormonal control of the menstrual cycle, the events of fertilisation and pregnancy, the stages of birth, patterns of human growth, and the range of contraceptive methods available, including how IVF can help couples who cannot conceive naturally.
Objectives
- Know that the process of fertilisation involves the fusion of a male and female gamete to produce a zygote
- Describe how a zygote divides to form an embryo
- Know the stages of meiosis allowing the production of haploid gametes and its significance in bringing about variation in a species
- Know the structure and function of the male and female reproductive systems
- Understand the roles of oestrogen, progesterone, FSH and LH in the menstrual cycle
- Explain the role in pregnancy of the hormone progesterone, placenta, amniotic fluid and umbilical cord
- Know the roles of oestrogen and testosterone in the development of secondary sexual characteristics
- Describe the birth process and explain the advantages of breast feeding
- Describe an outline of growth and development to maturity, to include growth curves for humans
- Describe the methods of contraception by hormonal, barrier and natural methods, intra-uterine devices and sterilisation
- Describe the advantages and disadvantages of each contraceptive method
- Describe the process of IVF and how it can improve the chances of pregnancy
