The embryonic time comprises 56 days, i.e., 8 weeks from the moment of fertilization. This time span is divided into 23 Carnegie stages and the stage classification is based solely on morphologic features. Carnegie stages are thus neither directly dependent on the chronological age nor on the size of the embryo. This can be illustrated by two examples: The closure of the rostral neuropore occurs by definition in stage 11 and that of the caudal neuropore in stage 12.
