A personal message from Dr Mark Hill (May 2020)

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!

Key Events of Human Development during the seventh week (week 7) following fertilization or clinical gestational age GA week 9 (LMP).

This period corresponds to Carnegie Stages 18 and 19.
