21.   Describe some disorders of each of the special sense organs.
 
Vocabulary:  (You will be quizzed on these words at the BEGINNING of the unit.  This is done before the student begins to read the text.  Research has shown that students are more likely to read and understand assignments if they have already been exposed to unfamiliar words.)
