What layer of the epidermis is the layer where mitosis occurs?
We find it in the deepest layer of the epidermis called Stratum Basal in which the stem cells undergo Mitosis replacing keratinocytes lost at the stratum corneum, the apical surface of epidermis.
What pigment is phagocytized by keratinocytes?
Melanocytes phagocytize melanin. First, melanocytes which are present in the lowest or basal layer of the epidermis, produce the pigment melanin. The melanin forms granules called melanosomes. After the keratinocytes take up the pigment, it clusters around the keratinocyte nucleus on the superficial side. This protects the DNA in the keratinocyte nucleus from damage due to UV radiation.
What is the function of the melanocytes?
- A cell of the statum basale of the epidermis that synthesizes melanin and transfers it to the keratinocytes.- Any of the dendritic clear cells of the epidermis that synthesize tyrosinase and, within their melanosomes, the pigment melanin; the melanosomes are then transferred from melanocytes to keratinocytes.
What type of cell is responsible for the color and tone of our skin?
There are cells within the bottom layer of the epidermis (the stratum basale or stratum germinativum) called melanocytes. Melanocytes secrete a pigment called melanin which is responsible for giving our skin its color. Their main function though is to shield the nuclei of the keratinocytes (the main cells of the epidermis) to protect them from ultraviolet radiation from the sun. That's why we appear to tan in the sun.

What cell type and cell product protect the skin from UV irradiation?
The cells in the dermis and epidermis called keratinocytes produce melanin in response to UV light in sunlight.
What is the Tiny openings in the skin called?
The outer layer of the skin, the epidermis, consists mainly of cells called keratinocytes.
What pigment is phagocytized by keratinocytes?
Melanocytes phagocytize melanin. First, melanocytes which are present in the lowest or basal layer of the epidermis, produce the pigment melanin. The melanin forms granules called melanosomes. After the keratinocytes take up the pigment, it clusters around the keratinocyte nucleus on the superficial side. This protects the DNA in the keratinocyte nucleus from damage due to UV radiation.
What ate the 4 types of cells in the epidermis?
The epidermis has several strata (layers) that contain four cell types. Keratinocytes produce keratin, a protein that gives skin its strength and flexibility and waterproofs the skin surface. Melanocytes produce melanin, the dark pigment that gives skin its color.
What tissue composes epidermis?
The dermis consists of two layers of irregular dense connective tissue proper: the more superficial papillary layer and the deeper reticular layer. The epidermis (top layer) is a keratinizing stratified squamous epithelium.
What is a wound that scrapes off the epidermis called?
A wound that scrapes off the epidermis (or part of the epidermis) is called an abrasion.
Epidermis is commonly called bark?
Epidermis is commonly called skin, not bark.
What is the function of the melanocytes?
- A cell of the statum basale of the epidermis that synthesizes melanin and transfers it to the keratinocytes.- Any of the dendritic clear cells of the epidermis that synthesize tyrosinase and, within their melanosomes, the pigment melanin; the melanosomes are then transferred from melanocytes to keratinocytes.
What is the layer of skin that you can see?

The outermost tissue of a young plant is called?

What is the outer cell layer of a cnidarian called?
