\(y=\frac{1}{x}\) 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.
Trauma is the most common cause of a hematoma. When people think of trauma, they generally think of car accidents, falls, head injuries, broken bones, and gunshot wounds.Trauma to tissue may also be caused by an aggressive sneeze or an unexpected twist of a limb.he greater the amount of bleeding that occurs, the larger the amount of clot formation. Blood vessels that are fragile may contribute to hematoma formation. For example, an aneurysm or weakening in a blood vessel wall may spontaneously leak.
