Ptosis Quotes

Your cells are preprogrammed to die naturally to make way for fresh cells through a process known as apoptosis (from the Greek ptosis, falling, and apo, away from). In a sense, your body is rebuilding itself every few months16 with the building materials you provide it through your diet. Some cells, however, overstay their welcome—namely, cancer cells. By somehow disabling their own suicide mechanism, they don’t die when they’re supposed to. Because they continue to thrive and divide, cancer cells can eventually form tumors and potentially spread throughout the body.

We have followed the general practice in referring to the nominative form as a "case" among four other cases. However, some modern grammarians have developed an account which goes back to Aristotle and according to which the term "noun" ('onoma') should be reserved for the nominative form, which names ('onomazein') simply, with no indication of a relation to other elements in the sentence. From its base (or "upright" or "straight" -- 'orthe', 'eutheia') form and function, a noun may undergo a "fall" ('ptosis', Latin 'casus', whence English 'case') or "inclination" ('klisis', from 'klino') towards other elements within the sentence. The roster of such fallings off is called a 'declension'. Although it is convenient to include the nominative form among the "cases," we shall occasionally refer to the other four as the 'oblique' cases.
