Show answer & explanation
Correct answer: B — Deposition of monosodium urate crystals
Gout is a form of inflammatory arthritis caused by the deposition of monosodium urate crystals in the joints, which leads to intense pain and inflammation.
Q2. Which term best describes the characteristic pattern of joint involvement seen in many forms of arthritis?
Show answer & explanation
Correct answer: C — Symmetrical
Many forms of arthritis, especially inflammatory types like RA, often present with symmetrical joint involvement, affecting similar joints on both sides of the body.
Q3. Which component provides smooth, friction-reducing movement between bones in a synovial joint?
Show answer & explanation
Correct answer: D — Articular cartilage
Articular cartilage is the smooth layer of hyaline cartilage covering the ends of bones in a joint, which reduces friction during movement.
Q4. Osteoarthritis primarily involves the degeneration of which specific tissue in the joint?
Show answer & explanation
Correct answer: D — Articular cartilage
Osteoarthritis is characterized by the progressive breakdown and degeneration of the articular cartilage.
Q5. Rheumatoid Arthritis is an example of which type of arthritis?
Show answer & explanation
Correct answer: B — Inflammatory Arthritis

Q6. Which of the following is the most common form of arthritis, primarily affecting the aging population and characterized by degenerative changes in the cartilage of weight-bearing joints?
Show answer & explanation
Correct answer: C — Osteoarthritis
Osteoarthritis (OA) is the most common form of arthritis, characterized by the progressive breakdown and degeneration of articular cartilage, particularly in weight-bearing joints.
Q7. Gout is a type of arthritis caused by the accumulation of which substance in the joints?
Show answer & explanation
Correct answer: B — Uric acid
Gout is caused by the deposition of uric acid crystals in the joints, leading to intense pain and swelling.
Q8. The primary cause of inflammation in Rheumatoid Arthritis is related to which type of immune cell activity?
Show answer & explanation
Correct answer: C — T-lymphocytes
Rheumatoid arthritis is an autoimmune disease primarily driven by an overactive immune response involving T-lymphocytes attacking the joint lining.
Q9. Which term is used to describe inflammation of the joints in the body?

Q11. Which fluid is found in the synovial joints and provides lubrication and nutrition to the cartilage?
Show answer & explanation
Correct answer: A — Synovial fluid
Synovial fluid is the specialized fluid found in the cavities of the synovial joints that reduces friction and nourishes the cartilage.
Q12. Which type of joint is most commonly affected by degenerative changes leading to Osteoarthritis?
Show answer & explanation
Correct answer: A — Hinge joints
Osteoarthritis primarily affects joints where the articular cartilage wears down, which is most prominent in hinge joints (like the knee and hip) and interphalangeal joints.
Q13. Which condition involves the excessive accumulation of uric acid crystals in the joints, leading to painful inflammation?
Show answer & explanation
Correct answer: A — Gout
Gout is a form of arthritis caused by the deposition of uric acid crystals in the joints.
Q14. Gout is a form of inflammatory arthritis caused by the deposition of which specific substance in the joint space?
Show answer & explanation
Correct answer: A — Uric acid crystals
Gout is caused by the accumulation of monosodium urate crystals in the joints, leading to intense inflammation and pain.
Q15. Which of the following joints is most commonly affected by severe degenerative changes leading to Osteoarthritis?
Show answer & explanation
Correct answer: B — Hip and knee joints
The hip and knee joints are major weight-bearing joints and are highly susceptible to degenerative changes seen in Osteoarthritis.
