 Definition
ARTICULAR CARTILAGE
Term
122.                        As cartilage ages, articular cartilage _____ becomes stiffer because advanced glycation end products accumulate and produce increase cross-linking. These changes in cartilage which occur at a highly variable rates, make cartilage less able to handle mechanical stress.
 Definition
