The function of the embryonic endoderm is to construct the linings of two tubes within the body. The first tube, extending throughout the length of the body, is the digestive tube. Buds from …

Endoderm, the innermost of the three germ layers, or masses of cells (lying within ectoderm and mesoderm), which appears early in the development of an animal embryo. The endoderm …

2013年11月17日 · Endoderm is one of the germ layers—aggregates of cells that organize early during embryonic life and from which all organs and tissues develop. All animals, with the …

The endoderm is a progenitor tissue that, in humans, gives rise to the majority of internal organs. Over the past few decades, genetic studies have identified many of the upstream signals …

The endoderm contributes the epithelia and glands of the gastrointestinal tract, respiratory tract and the renal bladder. This layer also contributes to the associated gastrointestinal tract organ …

endoderm or endoblast the embryological germ layer in animals that gives rise to the gut system and its association organs. It arises initially as a result of GASTRULATION from cells which …

Endoderm is the innermost germ layer of eumetazoan embryos, surrounded by mesoderm and ectoderm (Figure 13.1 A). The endoderm contributes to the epithelial lining and associated …
