\(y=\frac{1}{x}\) 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.
Contusions to the brain resulting from a blow to the head can result in a traumatic brain injury (TBI). Concerns when you suffer a laceration include bleeding, infection, pain, damage to structure beneath the skin, and future scars. A deep cut may expose underlying tissues, such as fat, tendon, muscle, or bone.
