Introduction

Stage22-UG-icon.jpg Movies - Embryo Carnegie stage 22 - This embryo animation rotates and show the relative position of internal renal system structures at the end of embryonic development. Compare these with the earlier stage 13 embryo.

The movies are based upon reconstruction of serial slice images.
