The innermost of the three primary germ layers of the embryo (ectoderm, mesoderm, endoderm); from it are derived the epithelial lining of the primordial gut and the epithelial component of the glands and other structures (e.g., lower respiratory system) that develop as outgrowths from the gut tube.ndoderm. the innermost of the three primary germ layers of the embryo; from it are derived the epithelium of the pharynx, respiratory tract (except the nose), digestive tract, bladder, and urethra. Called also endoblast, entoderm, entoblast, and hypoblast.
This means that they have three different germ layers. In between the endoderm and the ectoderm is a layer called the mesoderm. Each of these tissue layers will develop into different adult structures. For example, in humans: 1  Ectoderm: develops into your nervous system (brain and spinal cord) and outer skin layer.iploblastic animals have a gastrula with only ectoderm and endoderm layers. Triploblastic animals have a gastrula with ectoderm, endoderm, and mesoderm layers. These embryonic tissue layers will eventually develop into all the different tissues and structures found in an adult animal.
