OCD. Dermatophagia (from Ancient Greek δέρμα — lit. skin and φαγεία lit. eating) or dermatodaxia (from δήξις, lit. biting) [ 3] is a compulsion disorder of gnawing or biting one's own skin, most commonly at the fingers. This action can either be conscious or unconscious [ 4] and it is considered to be a type of pica.
Dermatillomania (picking of the skin) of the knuckles (via mouth), illustrating disfiguration of the distal and proximal joints of the middle and little fingers Body-focused repetitive behavior ( BFRB ) is an umbrella name for impulse control [ 1 ] behaviors involving compulsively damaging one's physical appearance or causing physical injury.
Blaschko's lines, also called the lines of Blaschko, are lines of normal cell development in the skin. These lines are only visible in those with a mosaic [ 1][ 2][ 3] skin condition or in chimeras where different cell lines contain different genes. These lines may express different amounts of melanin, [ 4] or become visible due to a differing ...
Specialty. Dermatology. Psychiatry. Excoriation disorder, more commonly known as dermatillomania, is a mental disorder on the obsessive–compulsive spectrum that is characterized by the repeated urge or impulse to pick at one's own skin, to the extent that either psychological or physical damage is caused. [ 4][ 5]
Langer's lines. Langer's lines, Langer lines of skin tension, or sometimes called cleavage lines, are topological lines drawn on a map of the human body. They are parallel to the natural orientation of collagen fibers in the dermis, and generally parallel to the underlying muscle fibers. Langer's lines have relevance to forensic science and the ...
Stretch marks, also known as striae ( / ˈstraɪiː /) [citation needed] or striae distensae, [ 1] are a form of scarring on the skin with an off-color hue. Over time, they may diminish, but will not disappear completely. Striae are caused by tearing of the dermis during periods of rapid growth of the body, such as during puberty or pregnancy ...

The incremental inductance rule, attributed to Harold Alden Wheeler [ 1] by Gupta [ 2]: 101 and others [ 3]: 80 is a formula used to compute skin effect resistance and internal inductance in parallel transmission lines when the frequency is high enough that the skin effect is fully developed. Wheeler's concept is that the internal inductance of ...
