What type of tissue makes up the epidermis?

The epidermis is composed of epithelial tissue, which serves as a protective barrier for the body. Epithelial tissue is characterized by closely packed cells that form layers and are involved in functions such as protection, absorption, and sensation. In the skin, the epidermis specifically consists of keratinized stratified squamous epithelium, which provides durability and resistance to water loss as well as protection against external environmental factors.

Epithelial tissue is distinct from connective, muscle, and nervous tissues. Connective tissue supports, binds, and protects other tissues and organs in the body, while muscle tissue is responsible for movement, and nervous tissue facilitates communication through the transmission of nerve impulses. These other types of tissues either do not form the outermost layer of the body or serve different primary functions compared to the protective role of the epidermis.
