Introduction

Embryology is a cornerstone of both Medical Education for medical students and Developmental Biology for science students. In this presentation I will explore how the teaching of Embryology has evolved in our Medical School with the entry into the digital age and the expansion of new teaching and research techniques.


This entire presentation will remain available online if you would like to explore in your own time!

Early History

Anatomies

Carnegie and Blechschmidt Models

Carnegie Models

Osborne O. Heard (1891–1983) produced over 700 wax-based embryo reconstructions models for the Carnegie Institute. Models were produced by the lost-wax casting process and were more detailed than the earlier Ziegler (1880's) embryo models.

Blechschmidt Models

Erich Blechschmidt (1904–92) independently developed new methods of embryo reconstruction, 200,000 serial sections of embryos and 64 models. (University of Goettingen, Germany)

Animal Models

  • Experimental embryology - involving manipulation of animal models.
  • Imaging development - electron microscopy, fluorescence microscopy, confocal microscopy, ultrasound, tomography.
  • Research fields - molecular biology, in vitro fertilisation, stem cells.

Recent Embryology Education

Anatomy teaching USA graph.jpg

Trends in anatomy disciplines contact teaching hours based on data from USA survey.

Less contact time, but a growing list of new clinically relevant topics.

Embryo Serial Sections

Microfiche reader.jpg Microfiche Reader used in Medicine and Science classes from 1975 to 1995.

View embryo section 49 images (7x7 matrix) in 3 sets:


  1. Stage 13 Embryo (mid-embryonic period)
  2. Stage 22 Embryo (end embryonic period)
  3. Selected Stage 22 images (selected organs and tissues from end embryonic)


Identify key organs and tissues in these sections and compare appearance at different periods of development.

2004 New Medicine Program

  • Previously lectures and practicals covering a semester.
  • Embryology became "integrated" into new cross-discipline courses.

Lecture Example

BGD - Development of the Embryo/Fetus 1

  • Replace powerpoint slides
  • Can be formatted for printing
  • Accessible at all times (including Mobile Access)
  • Can be opened during associated practical class
  • Links to:
    • Textbooks
    • Related online pages, including practical, audio etc.
    • Movies
    • Glossary

Practical Example

BGD - Practical Fertilization to Implantation

  • Organised into a timeline
  • Each page worked through with the demonstrator
  • Independent time to ask questions
  • Students can cut n paste for their own notes
  • Online Quizzes | Category:Quiz

Student Project Examples

Medicine Student Projects

  • Part of the Medicine undergraduate program allows for individual students to work on research or educational projects related to medicine.
  • The projects are academically supervised and are described as an "Independent Learning Project" (ILP).

Science Student Projects
  • Since 2009 undergraduate science students have been preparing online group projects as part of their ANAT2341 Embryology course.
  • Student group (4-5 students) selects a specific topic within the main theme that they then research and work collaboratively on that topic throughout the semester.
  • Project is discussed online.
  • Assessed by peers, before being finally edited for submission as their group assessment component for the course.
  • Group and Individual contributions can also be monitored.

Final Remarks

  • I remind you that I do not intend to cover everything shown on this seminar page. Some content can be returned to and studied in your own time.
  • Embryology education will continue to evolve online as new technologies and research techniques are developed.
  • Finally, and most importantly, I thank all my Contributors who have helped make this a site so rich in embryology content.
