Short Answers (1 point each)

1) This is an autoimmune disease that involves production of antibodies that interfere with nerves

stimulating muscle contractions. Face and neck muscles are the most obviously affected,

manifesting as drooping eyelids, double vision, difficulty swallowing and general fatigue. There

is no actual paralysis of muscles involved, but a rapid fatiguing of function.

Answer: __________________________________________________________

2) If not enough calcium is deposited during early childhood development, the bones do not

become rock-hard, but rubbery. Both adequate calcium in the diet and vitamin D, primarily,

from normal sunlight exposure or supplementation, are necessary for normal bone

development. Before vitamin D supplementation to milk, this was common resulting in the

classic bowed legs of the afflicted child.

Answer: __________________________________________________________

3) A highly contagious skin infection that is most common in children. It is caused by the

staphylococcus aureus, or more rarely streptococcus pyogenes bacteria. Children account for

about 70% of all cases. The first sign is a patch of red, itchy skin. In colder countries, most cases

are caused by staphylococcus aureus while in warmer countries the infection can be caused by

both types of bacteria.

Answer: __________________________________________________________

4) A chronic inflammatory disease that occurs when your body's immune system attacks your own

tissues and organs. Inflammation caused can affect many different body systems — including

your joints, skin, kidneys, blood cells, brain, heart and lungs.

Answer: __________________________________________________________


11

5) The most obvious symptom is a red, irritated lump under your skin. Touching it may be painful.

It can range from the size of a lentil to the size of a medium-sized mushroom. The lump quickly

becomes filled with pus. Nearby areas may also experience swelling. Other symptoms may

include: itching before the lump appears, bodily aches, fatigue, fever, skin crustiness or oozing.
