About Carnegie Stage 17
Most embryos at stage 17 are approximately 41 postovulatory days old and measure 11-14 mm in length. Distinguishing criteria for this stage include distinct digital rays in the hand plate, a rounded digital plate in the foot, a complete complement of hillocks on the mandibular and hyoid arches, distinct nasofrontal grooves, and a slight indication of a lumbar curvature.

Notice:
This specimen does not represent normal development. The caudal nueral tube has failed to close properly. Also, the MRI data suggest that this specimen was slightly dehydrated during imaging (evident in the midbrain and hindbrain).
