Corneocytes are cells in the stratum corneum, which is the outer skin layer. Corneocytes are stacked to form slightly overlapping columns perpendicular to the skin surface. Individual corneocytes are held together by desmosomes, which bridge adjacent epithelial cells, and by intercellular lipids that seal the space between adjacent cells. The main lipid constituents are cholesterol, free fatty acids, and ceramides. Lipid molecules are covalently bound to the corneocyte membrane and also orient in crystalline multilamellar structures in the intercellular space, forming a tight junction and creating a high resistance to penetration between the cells within the tight clusters.
What else can I help you with?
What is the name of dead skin cells?
Stratum cornelum and or stratum licidumThe skin cell.
What is The layer of the epidermis where the cells are considered protective but nonviable?
The outermost layer of the epidermis, known as the stratum corneum, is comprised of cells called corneocytes that are protective but nonviable. These cells are essentially dead and serve to provide a barrier against external aggressions like pathogens and UV radiation.
How do dead cells on the epidermis help the body?
Dead cells on the epidermis, known as corneocytes, play a crucial role in providing a protective barrier for the body. These cells are constantly shed and replaced by new cells underneath, helping to maintain the integrity of the skin. Additionally, the dead cells help to prevent water loss and protect the body from external pathogens and UV radiation.

What is the top layer of epidermis made from?
The top layer of the epidermis is called the stratum corneum and is primarily composed of dead skin cells called corneocytes. These cells are tightly packed together to form a protective barrier that prevents water loss and protects against external environmental factors.
The cells that make up the epidermis are both living and?
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.
What layer of the skin contains all or mostly dead cells?
The outermost layer of the skin, called the stratum corneum, contains mostly dead cells called corneocytes. These cells are constantly being shed and replaced with new cells from the underlying layers of the skin.
Is the epidermis dead?
Dead Epidermis refers to dead upper skin layers in humans and animals. The skin has two layers, the Epidermis (which is on the very surface) and the much thicker Dermis, which lies below and forms the main body of skin. Every so often, parts of the epidermis die and flake off, to be replaced by a new one that grows to take it's place. This is to keep the skin clean, and get rid of harmful bacteria that get trapped in the Epidermis.

What are the 7 layers of the outermost layers of skin found in the palm of the hands or soles of the feet?
The stratum lucidum is only found in the palms, fingertips, and soles.
What is a stratum of the skin?
As best I can tell it seems to be a typo or OCR error for "stratum corneum," which is the outermost layer of skin cells.
