The following questions are designed to make you think about clinical issues associated with this early stage of embryonic development. The answers will not be provided in the Lab and but will be available on the web. You will need internet access to use some of the links in this exercise.
Please note that questions are not directly examinable.
(UNSW Embryology Links are from the Embryology CD also available on the Web)
1. What is chorionic villus sampling (CVS)?
2. What does CVS show and what alternative tests are available?
3. What are the effects of high levels of maternal alcohol on the developing embryo?
4. What other maternal conditions can affect development of the embryo?
5. How are birth defects monitored in Australia?
6. What is OMIM?
Laboratory 11 Covers later stages of development in the fetus.
Movie of Human Embryo Growth(this shows a human embryo growing, all images are to scale)
Movie of Limb Growth(this shows development of the human arm from bud to paddle, to hand with arm)
Movie of Mouse Embryo Growth(this shows a mouse embryo growing)
Movie of Rotating Embryo(this shows an early embryo from all angles)
All Moviesthis shows many different ways of looking in at changes in different embryos.

Note- These notes are under development for this current year 2004.
This second embryology practical will continue on from implantation to cover the Embryonic period of development.
It should be obvious that this period of development is complex, and an entire class could be spent on folding or development of any one organ system. Therefore the Lab must be reasonably general in covering the details of folding and organogenesis.
If you are interested in a more detailed coverage, look at the Carnegie and Systems sections of Notes (from the lefthand menu).
