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.
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.

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.
Developmental Notes - http://embryology.med.unsw.edu.au/devnote.htm (Menstrual Cycle, Week 1 -4, Placenta, Parturition, Postnatal)
Developmental Notes 2 - http://embryology.med.unsw.edu.au/devnote2.htm (Serial Images, Other Embryos, Abnormal Development, Molecular Development, Morphodynamic Development, Statistics, Health)
System Notes - http://embryology.med.unsw.edu.au/sysnote.htm (Heart/Cardiovascular, Respiratory, Coelomic cavity, Gastrointestinal Tract, Head and Neck, Neural,
Neural Crest, Eye Ear Nose, Endocrine, Urogenital, Musculoskeletal, Integumentary)
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.

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.Fetal Origins Hypothesis - http://embryology.med.unsw.edu.au/Defect/page10.htm
The Genome, Stem cells and Cloning so a page of recent topics in development and embryology can be seen at Embryology in the News

Recent changes/updates to the UNSW Embryology website can be found listed on the 2007 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.

Embryology research continues to rapidly expand in several different directions all at once (stem cells, genetic, molecular, biomechanical mechanisms, teratology and new animal models).
In addition, there are wonderful new ways of showing some of these dynamic mechanisms.
The UNSW Embryology site continues to track these trends and discoveries with currently over 2,200 pages of content.
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.
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 the content pages for that subsection of notes.
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.
