what is the target tissue in rheumatoid arthritis?
a) synovium
b) hyaline cartilage
c) periosteum
d) subchondral bone

Explanation:

Rheumatoid arthritis is an autoimmune disease. The immune system mistakenly attacks the synovium (the lining of the membranes that surround the joints). This leads to inflammation, pain, and swelling in the joints. Hyaline cartilage is more affected in osteoarthritis. The periosteum is a membrane covering bones and is not the primary target in rheumatoid arthritis. Subchondral bone changes can occur in various joint - related conditions but is not the initial and main target like the synovium in rheumatoid arthritis.

Answer:

A. synovium
