\(y=\frac{1}{x}\) 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.
Types of Open Wounds. A wound is when the skin is torn, cut (incisions), rugged (lacerations), grazed (abrasions) or punctured. In order to determine which treatment is recommended for a certain type of open wound it is useful to be able to describe the type of wound.
