Histology and Embryology 4.0

3. Histology And Embryology 1.0, 2.0, And 3.0

Histology and Embryology 1.0 refer to the early stages of these fields, which date back to the early 19th century. During this period, histology and embryology were primarily descriptive disciplines that relied on the use of simple microscopes to observe and classify tissues and embryonic structures. This period was characterized by the development of staining techniques that allowed researchers to visualize the different components of tissues, such as cells and extracellular matrices. As a milestone In the 19th century, histology advanced as scientists developed new techniques for staining tissues and making them visible under the microscope. One of the most important advances in this regard was the development of hematoxylin and eosin staining, which allows different types of tissues to be distinguished based on their color under the microscope (Alturkistani et al., 2016).
