Arthritis and Rheumatoid-Arthritis

Arthritis

Arthritis (from Greek arthro-, joint + -itis, inflammation; plural: arthritides) is a form of joint disorder that involves inflammation of one or more joints.

arthritis n : inflammation of a joint or joints

Arthritis \Ar*thri"tis\ ([aum]r*thr[imac]"t[i^]s), n. [L., fr. Gr. 'arqri^tis (as if fem. of 'arqri`tis belonging to the joints, sc. no`sos disease) gout, fr. 'a`rqron a joint.] (Med.) Any inflammation of the joints, including the gout. A variety of forms of arthritis are recognized, some of which (such as {rheumatoid arthritis}, also called {arthritis deformans} and {arthritis nodosa}) are chronic and progressive, and lead to incapacitation and deformity. [1913 Webster +PJC] ||

Rheumatoid-Arthritis

Rheumatoid arthritis (RA) is a chronic, systemic inflammatory disorder that may affect many tissues and organs, but principally attacks flexible (synovial) joints.

rheumatoid arthritis n : a chronic autoimmune disease with inflammation of the joints and marked deformities; something (possibly a virus) triggers an attack on the synovium by the immune system, which releases cytokines that stimulate an inflammatory reaction that can lead to the destruction of all components of the joint [syn: {atrophic arthritis}, {rheumatism}]
