Mark Hill.jpg
Project Concept by Dr Mark Hill, Anatomy, School of Medical Sciences, Faculty of Medicine, The University of New South Wales, Sydney, Australia.

This project went online in 1997 and has continued to be updated since that time. This page gives me the great pleasure to thank the many people who have contributed to the development of UNSW Embryology. Let me first apologise to any contributor I may have missed over the years. I thank especially, and dedicate this project to, my aunt who worked as a volunteer in my Lab on this project for many years.

A personal message from Dr Mark Hill (May 2020)  
Mark Hill.jpg
I have decided to take early retirement in September 2020. During the many years online I have received wonderful feedback from many readers, researchers and students interested in human embryology. I especially thank my research collaborators and contributors to the site. The good news is Embryology will remain online and I will continue my association with UNSW Australia. I look forward to updating and including the many exciting new discoveries in Embryology!


Beverley hill.jpg
This project is dedicated to Beverley Hill (1933 - 2001) who from 1996 - 2000 worked patiently on all facets of this project; preparing images, fixing text, links, and committing a tireless labour on my continual updates and changes.

Serial Images History

The original principle of using serial sections on microfiche cards was developed by Dr M. Smith, Prof. C. Watson and the late Prof. I. Tork in the early 1980's. The original 27mm Human embryo microfiche images were developed by Dr M. Smith and the 6mm Pig Embryo microfiche images by Dr M. Smith and Prof. I. Tork.

Anatomy Notes

The current notes written and compiled by Dr M. Hill used many different additional texts, research papers and internet resources. Specific texts are referenced in each section of notes "References" and "Textbooks" lists and in the discussion pages as "Background Reading".

Original website undergraduate Notes (Anat 2006) included with embryo serial images are edited with permission of Dr B. Freeman, from his Course Manual for Human Embryology (1995). Other staff and former staff who had contributed to these notes prior to 1989 are Dr M.S.R. Smith, the late Prof. I. Tork, Em. Prof. H.ZawTun, Prof. C.R.R. Watson and Prof. R. Wheeler-Haines.
