\(y=\frac{1}{x}\) 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.
An incision wound is a cut in the skin caused by a sharp object such as a knife, broken glass, scissors or surgeonâs scalpel. Incision wounds are âneatâ and the edges of the skin are usually smooth. A laceration is injury to the skin that results in the skin being cut or torn open.
