Quizplus · Accepted Answer

In rheumatoid arthritis (RA), all of the given options occur. The synovial membrane (lining) becomes inflamed and thickens, forming a mass (pannus) that invades and damages articular cartilage, leading to fibrosis and ultimately ossification. This can result in the fusion of bones in the joint, causing joint deformity and loss of function. Therefore, all the options are correct.
