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.

What are most cells of the epidermis?
The most abundant cells in the epidermis are keratinocytes.
What stratum is absent from most epidermis?
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.
What is the function of dividing cells found at the base of epidermis?
The stratum basale (the bottom layer of cells in the epidermis) functions to provide a constant source of new cells to form the skin. This counterbalances the number of cells lost at the surface.
The epidermis contains what?
The epidermis contains skin cells.
Which cells arise from bone marrow and migrate to the epidermis?
macrophages called epidermal dendritic cells
What is the life cycle of an epidermal cell?
The cells on the epidermis have definite life cycle. Each epidermal cell begins life deep in the epidermis, where cells divide to form new cells. The new cells gradually mature and move upwards in the epidermis as new cells form beneath them. After about two weeks, the cells die and become part of the surface layer of the epidermis. Hope this helps!!
Are the outermost cells of the epidermis living or dead?
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.
What kind of cells is the epidermis made of?
The epidermis consists of stratified squamous epithelium cells. These cells in the epidermis are dead cells surrounded by the protein keratin.
What are most cells of the epidermis?
The most abundant cells in the epidermis are keratinocytes.
What part of the skin are new cells formed?
They are formed at the bottom later of the epidermis.

The epidermis contains what?
The epidermis contains skin cells.
On which layer of epidermis are guard cells found?
epidermis.
What is syncytial epidermis?
Epidermis containing cells which have many nuclei formed due to fusion of many cells.
How do the dead cells of the epidermis help the body?
When These cells Die, They Become Part Of The Surface Layer Of The Epidermis.
