The original Centor criteria had four major criteria but the modified Centor criteria have five.

The term "angina" is derived from a Latin word which ...
However, they are largest relative to the diameter of the throat in young children. In adults, each palatine tonsil normally measures up to 2.5 cm in length, 2.0 cm in width and 1.2 cm in thickness.
