What is the epidermis made up of?

  1. Fibroblast cells

  2. Adipose tissue

  3. Squamous cells

  4. Epithelial cells

The correct answer is: Epithelial cells

The epidermis is the outermost layer of the skin and is mainly made up of epithelial cells. Fibroblast cells are found in the dermis, which is the layer beneath the epidermis. Adipose tissue is also found in the dermis, but it is not a major component of the epidermis. Squamous cells are a type of epithelial cell, but they make up a small portion of the epidermis, while other types of epithelial cells such as keratinocytes are more abundant. Therefore, D Epithelial cells, is the correct answer for what the epidermis is made up of.
