Verified step by step guidance

Understand that the primary germ layers are the ectoderm, mesoderm, and endoderm, which are the initial layers formed during embryonic development.

Recognize that epithelial tissues are one of the four basic types of tissues in the body, and they serve as coverings or linings of surfaces and cavities.

Learn that each of the three germ layers has the potential to differentiate into various types of tissues, including epithelial tissues.

Acknowledge that the ectoderm primarily gives rise to the epidermis and nervous system, but it can also form epithelial tissues.

Realize that both the mesoderm and endoderm also contribute to the formation of epithelial tissues, with the mesoderm forming structures like the lining of body cavities and the endoderm forming the lining of the gastrointestinal tract.
