\(y=\frac{1}{x}\) 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.
This is what causes immediate swelling and bruising in the area of the broken bone. This is known as a Haematoma, which means bleeding within the tissue. The damaged bone tissue at the edges of the fracture fragments die back and the dead cells release chemicals called Cytokines which initiate the healing process.
