Question

What are the three germ layers?

Answer 1

Germ layers:

1. Early in the development of the embryo, germ layers are formed.
2. The outer ectoderm, middle mesoderm, and inner endoderm make up this basic cell layer.
3. Since the ectoderm is the outside layer, it contributes to the body's outer layer. It produces some of the epithelial cells lining the skin, hair, salivary glands, skin glands, nerve tissues, and peripheral nervous system, among other things.
4. The innermost layer, known as the endoderm, is what gives the body's organs including the stomach, liver, and pancreas their internal linings. It creates many organs, including the stomach, colon, liver, lungs, and pancreas.
5. The middle layer, known as the mesoderm, develops after the ectoderm and endoderm. The dermis, muscle system, heart, bones, bone marrow, and blood, which are referred to as fluid connective tissue, are all produced by this layer.
6. The embryonic blastomere known as endo-mesoderm has not yet developed into endoderm and mesoderm. Both of the germ layers can develop from this layer.
