Introduction

Historically, an important way of teaching embryology is by direct observation of histological sections at different stages of development. Even today the best way to observe anatomical development and relationships is by direct observation in serial sections through the embryo and fetus. The sections below are from the original teaching set prepared at UNSW that were digitized and put online in 1996 as a teaching resource.

The images are available in at least two formats, an unlabeled set and a labeled set. In addition there are now 3D animations based upon reconstruction of the embryos from these serial sections.

Carnegie Stage 13

About Stage 13 Embryo Sections - This image is from a serial section of a 6mm CRL pig embryo with some features of the Stage 14 embryo. This embryo is approximately equal to the day 42 human embryo. Use these serial images to identify internal features and relationships that exist within the embryo at this stage. Then compare these images with the later features of the Carnegie stage 22 human embryo.
