The causes of #RheumatoidArthritis is unknown. Contributing factors may include: infectious. genetic and endocrine. The current theory is that a genetically susceptible individual develops abnormal antibodies against some antigen.This antibody is not recognized as "self," and the individual produces an antibody, known as RF (#rheumatoidfactor), against it. RF creates a cycle of inflammation within the joints which occurs in four stages1.) #Synovitis develpos: #Synovitis is the inflammation of the synovial membrane resulting in congestion and edema of the synovial membrane and joint capsule.2.) Pannus develops. The inflamed tissue will contain the following: a. T-lymphocytes: WBC's responsible for cellular immunity b. plasma cells: produce antibodies. c. fibrin: clotting fibers. These materials together are called "granulation tissue." The synovial membrane and the granulation tissue grow and form folds called "pannus" that infiltrate the joint cavity. #ajthetrainerPRMediaDavis🐢🔭☎🎥📷📖📰📡🔭📺🎥💻 (at Ajthetrainer Prmedia Davis) https://www.instagram.com/p/Bmxom3OgYf6/?igshid=1lxbxli43vyvj
