Time to update your Bookmarks!

2013 - UNSW Embryology has completed a move to a new online home (UNSW Embryology). Some links will now point to the new site pages and I will be not updating any content on this original site.

 

You will now be automatically forwarded to the new site.......

 

Introduction

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 the Quicktime Movies or Flash Movies are also a good place to start and each set of notes links to related animations.

 

Begin

carnegie stages

Begin by looking at the Carnegie stages and watching the changes in the embryo's appearance over the first weeks of development.

week1

An easy introduction is given by the week by week timeline of human development.

Young students there are simplified K12 notes.

Medicine students should start here (2009). Science students should start here

Want to see what is happening in Embryology? Have a look at Embryology News or Embryology site updates. Also see the recent discussion on Fetal Alcohol Syndrome.

Next

The Developmental Notes give information about early developmental processes and overviews of other developmental times and concepts.

Menstrual Cycle Week 1 Week 2 Week 3
Menstrual Cycle Week 1 Week 2 Week 3
Placenta Human Fetal Growth Parturition Postnatal Development
Placenta Fetal Birth Postnatal

 

The System Notes give information about later developmental processes grouped by embryological and anatomical systems. Each section of notes is organized in a similar way giving: an introduction, overview, developmental abnormalities, mid-embryonic (Carnegie stage 13), late embryonic (Carnegie stage 22), examples of structures, histology and developmental molecular mechanisms.

Neural Heart Musculoskeletal Gastrointestinal

Neural Crest Urogenital Endocrine Body Cavities
Neural Crest
Body Cavities
Head and Neck Senses Integumentary Respiratory

Finally

stage13 embryo rotation

The Movies pages show dynamic processes of development and will require both the Quicktime plug-in and a reasonably quick internet connection.

Other Embryos

Other Embryos

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 these and other species the Animal Embryos pages are a good start.

When things go wrong in Development

Abnormal Development- Australian Statistics

Abnormalities that can occur during development are often described as congenital defects, with the 2 major types being Genetic (inherited) and Environmental (maternal) derived abnormalities. Begin by the introduction page Abnormal Development and each section of notes, week by week and systems, has a page listing and describing related abnormalities.

There is also growing evidence that in utero conditions have a significant impact on future health outcomes, look at Fetal Origins Hypothesis.

Postnatal Development

Postnatal Development

Development does not stop at birth!

Postnatal development is a new section of notes covers issues relating to development after birth.

Medical and Science Students

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.

Embryology in the News

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)

Contents by Page

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.

Glossary

The glossary is an alphabetical list containing brief descriptions of terms and acronyms. There are also links to pages with more information related to the term.

The entire UNSW Embryology website can also be searched using the window below and located on each page.

The UNSW Embryology CD program Version 5.7 September 2006 has now been discontinued (More? UNSW Embryology DVD).

Recent additions to the original UNSW Embryology site can be found logged at Whats New? and have feedback shown at What People Say.....

The development of the new UNSW Embryology website continues with 1,000 pages, better structure for navigation, quizzes and the ability for online contributions. This original site will remain active as may groups have hardlinks to specific pages. As well as the latest findings in embryology, I am including more detailed historic embryology documents and redesigning how undergraduate and K12 content is presented. If you wish to update your links, send me an email with your current link and I will point you to the new page.

Have fun learning!
