What is the event called when an aircraft takes off and scrapes the tail undercarriage?
It's called tailstrike.
Name of outermost layer of the skin?
It depends on which structures you are calling skin. The skin is made of dermis and epidermis. The outer thin layer is the epidermis, but it itself, is made of 4-5 layers depending on where it is located on the body. The most outer and the thinnest of the epidermal layers is called the coreum. It is the layer that we shed as it dies off and falls off.
What does it mean when a wound is spurting?
the wound is letting off blood
At the site of a wound platelets set off reactions that eventually cause the production of a chemical called?
At the site of a wound, platelets set off reactions that eventually cause the production of a chemical called fibrin. Fibrin helps form a mesh-like structure that traps blood cells and forms a clot to stop bleeding and facilitate wound healing.
What is the name and function of the thicker layer of the cells next to the epidermis in the carrot?
The epidermis of a carrot is the outer part of the root. This part is usually what people peel off.
What is the Upper layer of skin where new cells grow?
The upper layer of skin where new cells grow is called the epidermis. The epidermis is continuously replenished by cell division in the basal layer, and as new cells are produced, older cells are pushed towards the surface where they eventually flake off.
Are the outermost cells of the epidermis living or dead?
Cells in the lower layers of the epidermis divide continually, producing new cells that constantly push through the layers of the epidermis. By the time those cells reach the outer layer of the epidermis, they are dead and ready to slough off.
What is true about the blood supply to the skin?
The blood supply to the skin comes from small vessels called arterioles that branch off from larger arteries. These arterioles deliver oxygen and nutrients to the skin cells and help regulate body temperature. The skin's blood supply is also important for wound healing and immune response.
Is the epidermis dead?
Dead Epidermis refers to dead upper skin layers in humans and animals. The skin has two layers, the Epidermis (which is on the very surface) and the much thicker Dermis, which lies below and forms the main body of skin. Every so often, parts of the epidermis die and flake off, to be replaced by a new one that grows to take it's place. This is to keep the skin clean, and get rid of harmful bacteria that get trapped in the Epidermis.
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!

How do you get scotch tape off of walls?
You can buy a razor blade at a hardware store. (Ace) and it scrapes scotch tape off easily. If you need to get the marks off use Goo Gone.
What happens to dead cells in the epidermis?
Dead cells in the epidermis are shed through a process called desquamation. New cells are constantly being produced in the lower layers of the epidermis, pushing older cells towards the surface where they eventually flake off. This shedding helps to keep the skin healthy and renewed.
