Question

Innervated structures of joints are all except?

• A. Synovium
• B. Capsule
• C. Articular cartilage
• D. Ligaments

Hint:

Which joint tissue is avascular and aneural hyaline cartilage?

Answer 1

The Correct Option is C

Step 1: The question asks which joint component lacks innervation. Sensory nerves to a joint follow Hilton's law, supplying the capsule, ligaments and synovial membrane.

Step 2: Articular cartilage is the odd one out. As hyaline cartilage covering the joint surface, it is avascular, has no lymphatics and carries no nerve fibres.

Step 3: This absence of nerves and vessels explains why damaged articular cartilage neither hurts at the cartilage itself nor heals readily.

Step 4: The synovium, the capsule and the ligaments all have a sensory supply, so the only correct exception is the articular cartilage.
