The portion of the skin that is composed of nonliving cells is the stratum corneum. This outer layer of the epidermis consists of flattened keratinocytes that are no longer viable but provide protection for the underlying layers of the skin.
The cornified layers of the epidermis, also known as the stratum corneum, are the outermost layer of the skin composed of dead, flattened keratinocytes that provide protection against environmental stressors and water loss. These cells are continuously shed and replaced by new cells from the underlying layers of the epidermis to maintain skin integrity and barrier function.
Stratified cuboidal epithelium is composed of multiple layers of cuboidal-shaped cells. These cells have rounded nuclei and are found lining larger ducts in the body, such as in certain parts of the kidney and the mammary glands. The stratified arrangement provides protection and support to the underlying tissues.

Stratified squamous epithelium is a type of epithelial tissue composed of multiple layers of flattened cells. It is found in areas that experience mechanical stress, such as the skin and lining of the mouth and esophagus.
Dead layers on the outside of cells are called the stratum corneum, which is the outermost layer of the epidermis in the skin. These dead cells are composed mainly of keratin and help protect the underlying skin layers.
composed of several or many cells.
Bone tissue is often deposited in several laminated layers and has a strong and durable matrix composed predominantly of collagen fibers and mineral salts, providing strength and protection to the cells embedded within.
The epidermis is divided into different layers: - Stratum corneum - Stratum lucidum - Stratum granulosum - Stratum spinosum - Stratum basale The stratum basale is made up of the cells which through mitosis replicate several times. Each of these cells goes up towards the surface by being "pushed" by the new cells in formation. Stratum basale is the place of "birth" of the cells that compose the rest of layers which form the epidermis.
