Endoderm gives rise to which of the following?

Endoderm gives rise to which of the following?

• A. Epithelium and glands of the gut
• B. Muscles of the gut
• C. Nervous tissue of gut
• D. Skin

Answer: (A)

Endoderm forms the lining of the gut tube and the glands associated with it. This layer gives rise to the mucosal epithelium of the digestive tract and to glands such as the liver and pancreas that develop from this lining. The muscular layers of the gut come from the mesoderm, while the gut’s nervous tissue mainly arises from ectodermal neural crest cells and neural tube derivatives, and the skin develops from surface ectoderm. So, the epithelium and glands of the gut are endodermal derivatives, making this the correct choice.
