\(y=\frac{1}{x}\) This means that the line y=0 is a horizontal asymptote. Horizontal asymptotes occur most often when the function is a fraction where the top remains positive, but the bottom goes to infinity. Going back to the previous example, \(y=\frac{1}{x}\) is a fraction.
Causes of Wounds. Wound causes can be internal or external in origin. Wounds of internal origin are mainly due to impaired circulation, neuropathy or medical illness. Wounds of external origin are due to an outside force or trauma that causes open or closed wounds.
Open wounds can be classified according to the object that caused the wound. The types of open wound are: 1  Incisions or incised wounds, caused by a clean, sharp-edged object such as a knife, razor, or glass splinter.2  Lacerations, irregular tear-like wounds caused by some blunt trauma.3  Lacerations and incisions may appear linear (regular) or stellate (irregular). contaminated wound, where the wound is as a result of accidental injury where there are pathogenic organisms and foreign bodies in the wound. 2  infected wound, where the wound has pathogenic organisms present and multiplying showing clinical signs of infection, where it looks yellow, oozing pus, having pain and redness.
