| About Carnegie Stage 19 Most embryos at stage 19 are approximately 47-48 post-ovulatory days old and measure 17-20 mm in length. Distinguishing criteria for this stage include straightening of the trunk, the limbs extend nearly directly forward, toe rays are prominent, but interdigital notches have not yet appeared in the foot. Although some of the photographs below show abnormal embryos, the animations and MRI slice images all depict normal embryos. Abnormal embryos are noted in the titles of the large photos when they are opened. |
