The epidermis is composed of multiple layers of epithelial cells, including keratinocytes, melanocytes, and Langerhans cells. It is the outermost layer of the skin and serves as a protective barrier against environmental factors.
when it's not dry
Trachea, bronchi, nasopharynx and male urethra
FOREHEAD
The cells that make up the epidermis are both living and dead. The top layer of the epidermis, known as the stratum corneum, is made up of dead cells called corneocytes. However, the lower layers of the epidermis contain living cells that are actively dividing and producing new skin cells.

False. Living keratinocytes do not exfoliate from the epidermis as dander. Dander is composed of dead skin cells that shed from the epidermis.

Tunica
Cells in the lower layers of the epidermis divide continually, producing new cells that constantly push through the layers of the epidermis. By the time those cells reach the outer layer of the epidermis, they are dead and ready to slough off.
The dermis is the layer of skin that contains only living cells. The epidermis contains both living and dead cells.
nonliving is epidermis teeth and hair. all cells are non living when they die and are replaced
Partially. The dermis and lower part of the epidermis are alive, but the outer layers of the epidermis consist of dead cells.
If you are talking about the epIdermis then it is the outer layer of a living thing. Plants and animals both have an epidermis which is why i cant say its the outer layer of skin lol hope that helped
