Human hand with arthritic predilection sites
Dorsal view of a left human hand with its muscles, tendons, and ligaments. The redly colored articular areas show internal inflammatory processes of bone and cartilage, which are medically referred to as arthritis (greek arthros = joint). There are different courses of this disease. Inflammation of the smaller finger and hand joints is often associated with rheumatoid arthritis, also called chronic polyarthritis.
