By embryonic sketch, we refer to the first cells through which a specific organ, tissue, or structure subsequently develops. Thus, in the case of the embryo, an outline is the first sign that indicates that a part of it is growing. When a woman is pregnant, the stumps can be identified by ultrasound scans that allow the embryo’s development to be tracked. At FastlyHealwe, explain the Definition of the embryonic sketch.

Embryonic sketch
Undifferentiated cell layer from which a particular organ, tissue, or structure develops; rudimentary initial vestige. It refers to any embryonic organ or apparatus that has not yet reached its final form.
The embryo develops progressively day after day. However, this process does not always have to occur in the same periods since it depends on the prenatal and postnatal phases. Therefore, a fetus can develop certain functions quickly and take longer to develop others. For this reason, it is essential to monitor development to detect changes and identify the embryonic buds that are appearing.
Elements that are identified in the first ultrasounds
- Gestational sac . It is the first structure detected in ultrasound and is visualized as a small sphere of liquid with distinct edges. It tends to grow about a millimeter per day. It can be visible through an ultrasound system, and under favorable conditions, it can be visualized in the fourth week, when the gestational sac only measures 2 millimeters.
- Yolk sac . It provides nutrients to the embryo while the circulation that unites it with the placenta develops. It is the second visible structure and can be detected as a small fluid-filled sphere within the gestational sac. It can be visible during the fifth week of pregnancy.
