Yes, the stratum corneum and stratum lucidum contain cells that are without a nucleus, and are dead.
stratum corneum (outest layer of the epidermis)
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.
Yes, the stratum corneum consists of layers of cornified dead cells. They are strong, full of keratin, and contain no nucleus.
Stratum cornelum and or stratum licidumThe skin cell.
Cornified keratinocytes
Stratum corneum
The stratum Basale contains the most cells of the epidermis. Through the process of enucleation and apoptosis, the number of cells decrease as you move up the strata (layers).
the stratum basale
The epidermis is the top and most superficial skin layer in the body and is made of dead skins cells. You will shed these dead skin cells and they will fall., so you don't have a continuously growing layer of dead skin.
No, the stratum corneum is made up of squamous (tile-like) cells, not cuboidal cells.
Skin cancer doesn't arise from the stratum corneum because that layer of the epidermis is composed mainly of dead cells that do not have a blood supply for cancer cells to use. Foremost the Stratum Corneum is the top layer of the Epidermis, a cutaneous membrane. It is to be noted that the Stratum Corneum consists of 25-30 layers of non-dividing or dead cells. Therefore this environment does not accomodate the malignant cancer cells that depend on a living healthy area in which to chronically divide.
