During the embryonic stage, significant developments occur such as the formation of the neural tube, head, blood vessels, and the beginning of major organs taking shape. A primitive heart also starts to beat. However, the growth from one ounce to two pounds is not characteristic of the embryonic stage; this level of growth occurs later in fetal development.
