Excoriation: A punctate or linear abrasion produced by mechanical means (often scratching), usually involving only the epidermis, but commonly reaching the papillary dermis. [ 30 ] [ 33 ] Ulcer : An ulcer is a discontinuity of the skin exhibiting complete loss of the epidermis and often portions of the dermis.
The word skin originally only referred to dressed and tanned animal hide and the usual word for human skin was hide. Skin is a borrowing from Old Norse skinn "animal hide, fur", ultimately from the Proto-Indo-European root *sek-, meaning "to cut" (probably a reference to the fact that in those times animal hide was commonly cut off to be used as garment).
Abrasion, under its strictest definition, is commonly confused with attrition and sometimes hydraulic action however, the latter less commonly so. Both abrasion and attrition refers to the wearing down of an object. Abrasion occurs as a result of two surfaces rubbing against each other, resulting in the wearing down of one or both of the surfaces.
An abrasion is a partial thickness wound caused by damage to the skin. [1] It can be superficial involving only the epidermis to deep, involving the deep dermis. Abrasions usually involve minimal bleeding. [ 2 ]
Abrasion (dental), the loss of tooth structure by mechanical forces from a foreign element; Abrasion (medical), a wound consisting of superficial damage to the skin; Abrasion (mechanical), the process of scuffing, scratching, wearing down, marring, or rubbing away; Abrasion (geology), mechanical scraping of a surface by friction between moving ...
Rawhide is a hide or animal skin that has not been exposed to tanning. It is similar to parchment, much lighter in color than leather made by traditional vegetable tanning. Rawhide is more susceptible to water than leather, and it quickly softens and stretches if left wet unless well waterproofed.
Antler comes from the Old French antoillier (see present French : "Andouiller", from ant-, meaning before, oeil, meaning eye and-ier, a suffix indicating an action or state of being) [3] [4] possibly from some form of an unattested Latin word *anteocularis, "before the eye" [5] (and applied to the word for "branch" or "horn" [4]).
There have been many different theories regarding the causes of excoriation disorder, including biological and environmental factors. [10]A common hypothesis is that excoriation disorder is often a coping mechanism to deal with elevated levels of turmoil, boredom, anxiety, or stress within the individual, and that the individual has an impaired stress response.
