Epidermis
Being replaced.
The epidermis is made up of dead skin cells. The cells are constantly falling off of the body, but are replaced by new cells that were earlier created in the dermis.
The epidermis is the outer layer of skin, this goes for almost all animals and plants. In mammals the epidermis consists of four to five separate layers, the top layer is made up of cornified cells, which form the primary protective layer. This layer is constantly renewed by releasing dead cells and advancing new cells. The bottom layer creates new cells which then start their journey to the top layer.

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 epidermis is the top layer of the skin. It is absent of nerves and blood vessels, therefore the epidermis is dead. The dead skins cells are constantly being replaced by new cells made in the dermis.
They originate in the deepest layer of epidermis, called stratum basale. The columnar cells of this deep layer are constantly dividing to produce new cells that move outward to undergo metamorphosis at different levels.
The basal layer, also called the stratum germinativum is the most active part of the epidermis and the place where new cell growth takes place.
The epidermis is made up of dead skin cells. The cells are constantly falling off of the body, but are replaced by new cells that were earlier created in the dermis.
The epidermis consists of stratified squamous epithelium cells. These cells in the epidermis are dead cells surrounded by the protein keratin.
The most abundant cells in the epidermis are keratinocytes.
