A. Osteoporosis
B. Tetany
C. Rheumatoid arthritis ✓ Correct
D. Gout
Solution: Rheumatoid arthritis is an autoimmune joint inflammation; osteoporosis is bone loss, gout is uric acid crystal deposition.

The hinge joint, which allows movement in only one plane (e.g. bending), is found at the:
A. Elbow and knee ✓ Correct
B. Shoulder
C. Neck (atlas–axis)

Osteoporosis, common in older people (especially post-menopausal women), is characterised by:
A. Inflammation of joints by the immune system
B. Low blood calcium causing muscle spasms
C. Excess uric acid in joints
D. Decreased bone mass and mineral density due to reduced oestrogen ✓ Correct
Solution: Osteoporosis is age/oestrogen-related loss of bone mass and density, raising fracture risk.
Q6 — Joints & Disorders · hard · theory
Gout is a joint disorder caused by the inflammation due to the accumulation of ______ crystals in the joints:
A. Uric acid ✓ Correct
B. Calcium carbonate
C. Oxalate
D. Cholesterol
