The embryonic origin of tissues and major organs is a foundational concept in developmental biology, illustrating how the three germ layers—ectoderm, mesoderm, and endoderm—give rise to the body’s complex structures. This article examines a detailed chart that maps out the differentiation pathways from these germ layers to specific tissues and organs, such as the nervous system, heart, and lungs. By exploring this chart, we gain a deeper understanding of how embryonic development shapes the anatomical and functional diversity of the human body.
