Introduction

There are many different areas and ways to explore in the UNSW Embryology Program.

Areas to explore will vary depend on your specific interests and How the program was accessed (Internet, class computer, CD). The Program is not designed to cover only one Course, but as a general Embryology Resource (UNSW Medical and Science Students please read this). For specific courses an instructor module page can be constructed. Currently there are Links to specific course lecture and practical classes from the Start Page.

Begin by looking at the Human Carnegie Stages of development, comparing developmental age with surface features that are visible on the embryo. If your computer has Quicktime installed there is also a Movie of Carnegie stages which shows the relative size at each stage. How does this staging/time of development compare with other embryos: chicken, rat?

There are then 2 main areas to explore....

1. Start with specific Developmental topics which covers very early development and other related issues.

This covers week 1- 4 of development, formation of the placenta, abnormal and postnatal development. Related issues include womens health, mens health, population statistics, law and ethics. There are also specific sections on genetics and other species that have been used to determine both molecular mechanisms and genes involved in development. Each page in these notes covers a specific issue.

2. Thengo to Systematic development which looks at how specific systems and structures form within the embryo. Sets of notes on each topic are organized in the same basic page order.

Page 1 - a general introduction, textbook references, list of computer activities, objectives, learning activities, developmental overview, References, terms.

Page 2 - system specific developmental abnormalities, links to full descriptions, links to current references and searchable www reference and OMIM abnormality database, self assessment questions.

Page 3 - selected extracts of serial images of the Carnegie stage 13/14 embryo. Note clicking the image or section name will open the full image.

Page 4 - selected extracts of serial images of the Carnegie stage 22 embryo. Note clicking the image or section name will open the full image.

Page 5 - selected extracts of high power images of the Carnegie stage 22 embryo and links to relevant histology images. Note clicking the image or section name will open the full image.

Page 6 - onward are additional pages found in some section notes, that are listed at the top of each page.

Page 11 - in some sections there is also a page of specific molecular mechanisms related to that topic or system. (this is in addition to the molecular mechanisms under developmental topics)

WWWPage - In each section there is a page of www links relevant to that sections notes.

Then look at the developing embryo by.......

3. Then look at an overview of early development by comparing detailed Serial Images of the early Carnegie stage 13/14 embryo with the late Carnegie stage 22 embryo (of the 23 Carnegie stages).

Unlabelled- Step through serial slices of the embryo in an unlabelled format identifying structures, looking a the relationships and presence/absence of different structures at both stages.

Labelled- Allows easy identification of key structures at both stages.

Tutorial- Test your knowledge of specific numbered structures in the embryo.

Movies- These slices can also be viewed as movies to see relationships within the embryo (better on CD than internet, as these are large files 2-3 Mb). Specific organs and tissues can also be seen in the selected highpower images of the Carnegie stage 22 embryo.

4. Finally look at the many different moives that demonstrate embryo growth, serial sectioning, developmental concepts, 3D rotaions of models, and ultrasound moives.

For detailed information Each section of developmental and systematic notes will also have extracts and links to these serial images. If you want to see all the program parts at once look at the sitemap or the notes index. Each section of notes also has a specific page with links to related internet resources and Histological images.

Alternatively read the information below about the different sections and the various control panels (?) in each of the sections.

CD	About the panels	The main opening page is the navigation link to all the sections available. If you are interested in working with the Embryology class images there are 2 major serial sections 6mm Pig and 27mm Human and a high power selected Human series to view. The Embryology class images can be viewed in 3 different ways: Unlabelled, Labelled and Tutorial. Below each image is a navigation panel (?) which has buttons that link to specific pages.
