In regeneration-competent animals, the newly formed epidermis , which is termed the wound epidermis , is distinguishable from the surrounding epidermis by its thick morphology Santos-Ruiz et al, Mature and juvenile tissue models of regeneration in small fish species. Garrod and his team used chemical cross-linking to study cells of the epidermis and found what they believe to be the principal mechanism by which the glue molecules of desmosomes of skin cells bind to each other.
Cell binding discovery paves way for skin, heart problem treatments. The surface epidermis is frequently ulcerated or crusted, sometimes showing excoriation if the lesion has been manipulated, scratched, or traumatized prior to biopsy figure 1.
Skin basal cell carcinoma. The projection of the epidermis is known as trichomes. In plants,these describe the spines, glands, thorns, and similar parts.

This layer of the skin is composed of several layers. The layers occur in those order from bottom up: This layer is beginning to die; melanocytes are contained here -Stratum Granulosum: This layer is mostly dead; a few are still alive, however for the most part the cells are just becoming more keratinized and more squamous -Stratum Corneum: Where is the epidermis?
The layer under the epidermas is called the dermis. What are the characteristics of the epidermis? The characteristics of the epidermis help it in playing its role.

Layer of epidermis that is the deepest, and is composed of columnar cells that are constantly undergoing mitosis Dermis The thicker layer of skin that has nerves and blood vessels, and is made of connective tissue. Anatomy and Physiology of the Integumentary System (Primary) Description. Term. Epidermis: Definition. this layer of skin contains mostly dead cells; composed of keratinized and nonkeratinized simple squamous epithelial tissue deepest layer of the epidermis composed of a single row of cuboidal or columnar keratinocytes; contains .
The epidermis is composed of 4 or 5 layers depending on the region of skin being considered. Those layers in descending order are:  cornified layer (stratum corneum). The epidermis is the outermost layer of our skin. Its main purpose is protection. The epidermis is made of four main layers, or strata: The stratum corneum is the thick, tough outer layer. It is made mostly of dead cells that slough off constantly. The stratum basale is comprised of new cells that are constantly dividing to replace the stratum corneum.
