Embryába

Embryába is a term used in some scientific contexts, particularly in discussions of early embryonic development. It refers to the stage of an organism's life cycle after fertilization but before it hatches or is born. This period is characterized by rapid cell division, differentiation, and the formation of basic body structures. The duration of the embryá stage varies significantly among different species, from a few days in some invertebrates to several months in mammals.

During embryá development, a single-celled zygote undergoes a series of mitotic divisions to form a blastocyst or a similar structure. This is followed by gastrulation, where the germ layers (ectoderm, mesoderm, and endoderm) are established, which will eventually give rise to all the tissues and organs of the organism. Organogenesis, the formation of organs, is a key process within the embryá stage. External factors such as temperature, nutrient availability, and exposure to toxins can influence the successful development of the embryá. Understanding the embryá stage is crucial for fields like developmental biology, evolutionary biology, and reproductive medicine.
