Connective tissues

Connective tissues are everywhere in the body, and so diseases affecting connective tissues can have wide-ranging effects. Choose one condition( I would like you to write about Rheumatoid Arthritis ) that affects one of the connective tissues we have studied, describe the normal histology of the affected connective tissue and the histology of the disease condition (you may wish to include comparative pictures of normal and abnormal histology). What effects does this have on the body, and how is the health of an affected individual impacted? Remember to cite the sources you used, including websites.
