embryological development

Embryological development is the process by which a fertilized egg grows and develops into a fully formed organism. It begins with fertilization, where a sperm cell merges with an egg. This forms a zygote, which divides and develops into a blastocyst, implanting in the uterus. Over weeks, it differentiates into various cell types, forming layers that give rise to organs and systems. Key stages include gastrulation, where the main body plan is established, and organogenesis, where organs develop. This intricate process is guided by genetic instructions, ultimately leading to the formation of a fetus capable of surviving outside the womb.
