The epidermis is composed of 4-5 layers depending on the region of skin being considered. Those layers in descending order are the cornified layer (stratum corneum), clear/translucent layer found only on the palms and soles (stratum lucidum), granular layer (stratum granulosum), spinous layer (stratum spinosum), and basal/germinal layer (stratum basale/germinativum). The term Malpighian layer (stratum malpighi) is usually defined as both the basal and spinosum layers as a unit
The Layers of the Epidermis are.
1- Stratum Corneum ( Most Superficial )
2- Stratum Granulosum
3- Stratus Spinosum
4- Stratum Basale or Basal Layer ( Deepest Layer )
* Stratum Corneum = keratinized,dead,flattened scale-like and non-nucleated cells which are continuously shed as flake-like residue. * Stratum Lucidum = thin,clean layers found only in epidermis of the lips,palms and soles. * Stratum Granulosum = one or more layers of granular cells that contain fiber ang keratin and shriveled nuclei. * Stratum Spinosum =spiny layer, several stratified layer of cells in contact with centrally located, large oral nuclei and spine like process. * Stratum Germinativum = basal layer, simple layer of cuboidal cells in contact with the epidermis.
From deepest to superficial: Stratum germinativum (also called "stratum basale"), stratum spinosum, stratum granulosum, stratum lucidum (palms & soles), and stratum corneum, the outermost layer that is composed of dead skin cells.

How many layers does the epidermis have in hair?
how many layer of cells make up upper epidermis and lower epidermis
The cells that make up the epidermis are both living and?
dead cells
What are the two kinds of cells that make up the epidermis?
squamous and cuboidal
How can you describe the similar cells that make up the make up epidermis tissue in the leaf and how other tissues have different shapes of cells?
The similar cells that make up epidermis tissue is chloroplasts. Other tissues have different shapes of cells because the chloroplasts are bigger so it is a different size than other tissues cells.
What is contained in the epidermis?
The epidermis in humans contains cells (melanocytes) that make melanin, which gives skin its colour, Langerhans' cells which are the front line of defense of the immune system in the skin, and normal cells which make up your skin.
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.
Is the epidermis made up of living and dead skin cells?
Yes, it is made up of living and dead cells.
Is the dermis made of mostly dead cells?
No, the epidermis is made up of mostly dead cells
What type of cells make up your skin?
Most of the skin is composed of the dermis which is made up mostly of dense irregular connect tissue. The cells about it are dead cells called the epidermis.
What is the function of these epidermis onion cells?
The root cell's job is to gather minerals and and take it up the roots to the onion.
On which layer of epidermis are guard cells found?
epidermis.
