Version 8.0
Animation of the Carnegie stages 1 to 23 of human embryonic development during the first 8 weeks (click to play).
Carnegie stage 1 to 23 of Human Development |
Your exploration of development can begin in many different ways. Follow the guide shown below (Begin, Next, Finally) or use the internal links shown on the left. These main linked pages will give you access to many different embryology resources. Development is a very dynamic process so Movies is also a good place to start and each set of notes links to related animations.
By looking at the Carnegie stages and watching the changes in the embryo's appearance over the first weeks of development. An easy introduction is also given by the week by week timeline of human development or K12 notes for young students and 2009 Medicine students should start here.

Want to see what is happening in Embryology? Have a look at Embryology News or Embryology site updates.
Recent discussion on Fetal Alcohol Syndrome.
The Developmental Notes give information about early developmental processes. Later development features can be seen in the System Notes. Each section of notes is organized in a similar way giving: an introduction, overview, developmental abnormalities, stage 13/14 and stage 22 examples of structures, histology and developmental molecular mechanisms.
For those wanting to see dynamic processes of development (and have a reasonably quick connection) then the Movies pages are good for watching changes occur.
The study of human development has relied extensively on studying the process in many other animal models (chicken, fly, mouse, zebrafish). For those wanting to see the process of development in other species then the other embryos pages are a good start.
Development does not stop at birth! This new section of notes covers issues relating to postnatal development.
Can find lecture and practical information on the Class Notes page. The 2009 Medicine content is linked below. Alternatively work through the Serial Images of the stage 13/14 and stage 22 embryo.

There are many different possible causes and outcomes, look at Abnormal Development. There is also evidence that in utero conditions have a significant impact on future health outcomes, look at Fetal Origins Hypothesis.
The Genome, Stem cells and Cloning so a page of recent topics in development and embryology can be seen at Embryology in the News (see also stem cells and cloning)
Recent changes/updates to the UNSW Embryology website can be found listed on the 2008 Log page.
A book content style of browsing can be found on Contents by Page. For those used to a More details on how to get started can also be found on the How to Use page.
To put reproduction in a quantitative perspective, there are a number of pages summarizing both Australian, International and World Population trends on Statistics page.
A history of medicine, including embryology, is given by H.S. Williams with additional links to other historical resources including childbirth and Nobel awards on History page.

The current UNSW Embryology website Version 8.0 January 2009.
The current UNSW Embryology DVD Version 7.8 released December 2008. (More? DVD Homepage | About DVD)
The UNSW Embryology CD program Version 5.7 September 2006 has now been discontinued (More? UNSW Embryology DVD).
Recent additions to the UNSW Embryology site can be found logged at Whats New? and have feedback shown at What People Say.....
Medical Students please note that the current site format will allow both didactic Embryology learning (serial sections) and Problem Based Learning (PBL modules under development).
I have also received a lot of email showing that this resource has been useful to researchers, students and the general public, for that I thank you. It encourages me to keep this site as up to date as possible.
For those interested, in collaboration with Prof Kathy Sulik I am currently adding a series of beautiful scanning electron micrograph images of early human embryos to the Carneigie stages section of the website.
Have fun learning!

What are these?
A new year and Embryology continues to amaze us with new findings (stem cells, genetic, molecular, biomechanical mechanisms, teratology and new animal models). New technical abilities allow us to label cells and their components in embryos and then to observe developmental dynamic processes. Stem cell research is unravelling differentiation and disease processes and surprizing potential roles in oncogenesis. Novel gene regulation through microRNA... while our understanding may change the developmental results are the same as those seen by the historic embryologists early last century.
I am also trialing several alternative online approaches (Mobile, Blog, Wiki) that should supplement the existing website. I hope the website is both informative and part of your own embryology education.
The UNSW Embryology site continues to track embryology trends and discoveries with currently over 2,300 pages of content. In 2008 there were 22 million hits representing 1,320,520 visitors.
There are many places to explore in this site, from growth of whole human embryos to molecular mechanisms of development. The lefthand menu shows the major linked subsections, which when entered will also show menu pages for that subsection of notes.
In collaboration with Prof Kathy Sulik I am currently adding a series of beautiful
scanning electron micrograph images of early human embryos to the Carneigie stages section of the website.
Human genes are 2.85 billion nucleotides of DNA, but so also is a chimpanzee, and all this DNA encodes only about 20,000-25,000 protein-coding genes.
In development, I am not that different from a mouse or a fly and many of the signals that regulate development are used time and time again.

The Google search window (lefthand menu) allows searching the entire site for a specific term or topic.
About the UNSW Embryology DVD for Educational Use.
There is also an extensive linked Glossary explaining many of the embryological terms.
Starting points include: embryo cross-sections (labeled/unlabeled/tutorial) for students to explore and compare, notes on early and system development, abnormalities and statistical data, development in other animals, links to external resources and research papers and even embryology in the news.
As well as this current long-term project, I have been recently developing a new educational tool for Science and Medicine students in UNSW Cell Biology.
My thanks to the many people who have contributed to the Project. Please enjoy your learning experience and email Dr Mark Hill if you wish to make a comment about this current project.
