Where do epidermal cells get their nutrients?
Epidermal cells receive nutrients and oxygen from the blood vessels in the dermis.
What is the epidermal layer?
The dermis. And uner the dermis is the hypodermis
What does the term epidermal tissue mean?
Epidermal means above (epi-) the dermis (main skin layer). The epidermal layer is made of dead skin cells which you shed all day long. They also make up most of what we call house dust.
How is damaged skin repaired?
Actually it is not that difficult for the skin to repair itself when only the epidermis is damaged. It's when the dermis is injured that the process becomes more complicated. It is difficult to only injure the epidermis, but it happens. The epidermis is avascular, meaning it does not contain blood vessels and therefore does not bleed. Epidermal wounds usually involve only minor damage to the superficial epidermal cells although the center of the wound could extend slightly into the dermis. These types of wounds include minor skin abrasions, where a portion of the skin has been scraped away, and minor burns. In response to an epidermal injury, basal cells from the deepest layer of the epidermis --the stratum basale-- surrounding the wound break off from the basement membrane (epidermal-dermal junction). The cells then enlarge and migrate across the wound. The cells continue to migrate until they meet cells migrating from the opposite side of the wound. Migration of the cells stops when each cell is finally in contact with other epidermal cells on all sides. As the basal epidermal cells migrate, a hormone called epidermal growth factor stimulates basal cells to divide and replace those who have left to fill in the wound. The relocated basal epidermis cells divide to build new strata, thus thickening the new epidermis. Viola, the skin is repaired!

What is the epidermal layer that produces new cells?
Stratum germinativum, also called stratum basale or basal cell layer.

Where are the plant epidermal cells found?
Structures in the dermis that help regulate body temperature are
What tissue associated with the skin and underlying tissues contains many cells that fight infection What are these cells called what process do they use to rid the body of organisms?
Our skin has two layers: (1) Epidermal layer and (2) Dermal layer.Micro-organisms that penetrate through the epidermal layer is trapped in dermal layer which has WBC's, mast cells that fight antigen.Dermal layer has two parts, papillary layer and dermis. Other processes in the dermis then gets rid of any waste collected in the papillary of epidermal layer.

What is the function of epidermal cells in sponges?
The epidermal cells of sponges are responsible for cell adhesion and maintenance of their shape and structure. The epidermis is composed of pinacocytes (epidermal cells) which are flattened cells in the sponge's body wall.
What are epidermal dendritic cells?
Langerhans cells

Does HIV attack epidermal cells?
HIV mainly attacks cells in the immune system. I'm not aware of a major impact on skin (epidermal) cells.
What is an epidermal cell?
An epidermal cell is a cell that is part of the outer layer of an organism. For example, in humans, skin cells are epidermal. Leaves on plants have epidermal layers on the top and bottom of the leaf.
