NUR 229 Lecture Notes - Lecture 5: Hyaline Cartilage, Rheumatoid Arthritis, Synovial Membrane
Document Summary
It is the most common type of arthritis that develops due to the deterioration of the articular cartilage. When this happens it leads to bone break down because the bones within the joint start to rub upon one another. This will cause changes inside and outside of the bone. The inside of the bone will start to experience abnormal hardening (sclerosis), and the outside of the bone will experience osteophytes formation (bone spurs). Oa is from wear and tear on the body rather than from on overactive immune system, which is the cause in rheumatoid arthritis (it affects the synovium not hyaline cartilage in ra). Bone cartilage is a rubbery, smooth tissue found within the joint that covers the end of each bone. It acts as a protective mechanism for movement by providing this slick surface for the bones to slide and glide during movement. The top layer of cartilage begins to breakdown and wear away.
