Development of Wattles in the Chicken Embryo

Abstract

In this study, 120 fertilized chicken eggs were collected and the eggs were divided into two groups, 60 eggs for each group, and placed in the silage at a temperature of 37 °C. These two layers arise from two different sources, where the epidermis arises from the ectoderm and is one layer at the beginning of formation and then multiplies, while the dermis arises from the mesoderm and is in multiple forms. wattles are. made up of two layers, the epidermis and the dermis two layers are created. in the area of the pendants from two. different source The tissue component.s of the pendants are the same as. the tissue components of the skin, but differ. from it in the thickness of the layers. and more blood vessels.
