The main structural component is made of proteins Correct!
, Helps with the conduction of electrical currents in nerve and muscle cells

Question 5
pts
Compare and contrast the two types of gangrenous necrosis. Your
Answer:
Dry gangrene occurs when blood supply is slowly reduced to an area. The area is dehydrated and
becomes dark or black in color. Commonly seen in patients with diabetes. It is not very painful,
but tissues eventually die.
Wet gangrene is casued with a sudden reduction in blood flow. The area is cold and swollen, with
no pulse. This can occur from trauma. Bacteria is involved and is very painful. It has the
appearance of pus, becasue it looks wet. There is also a foul smell.
In dry gangrene the affected tissue becomes dry and shrinks, the skin wrinkles, and its
color changes to dark brown or black. The spread of dry gangrene is slow. It results from a
cut off in arterial blood supply and is a form of coagulation necrosis. In wet gangrene, the
affected area is cold, swollen, and pulseless. The skin is moist, black, and under tension.
Blebs form on the surface, liquefaction occurs, and a foul odor is caused by bacterial
action. The spread of tissue damage is rapid.
