\(y=\frac{1}{x}\) 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.
These include: If the skin is torn and you have skin flap. The wound is large, deep or gaping and may require stitches. The wound is dirty or there is something in it. It is a puncture wound, which may have been caused by standing on a nail or an animal bite.
