Introduction

Human Embryo

This Embryology category shows some key events of human development during Week 8 of the embryonic period of the first eight weeks (weeks 1 - 8) following fertilization. This period is also considered the organogenic period, when most organs within the embryo have begun to form.

Note post-fertilisation (ovulation age) Week 8 corresponds to clinical Gestational Age GA week 10 (add 2 weeks).

There are links to more detailed descriptions which can be viewed in a week by week format, by the historic Carnegie stages or integrated into a Timeline of human development.

Online resources available include: individual images of all Carnegie stages, scanning electron micrographs of the earlier stages, cross-sections showing internal structures at mid- and late-embryonic, 3D reconstructions of internal structures, animations of processes, ultrasound scans and information about abnormalites of development.

Note that there is variability in the actual timing of specific events and at the end of this period fetal development begins.
