Question

What are true for the collagen fibres?

• A. Part of skeletal system, strongest of all fibres and responsible for skin strength
• B. Part of skeletal system, and one of the strongest fibres
• C. Part of muscular system, and strongest of all fibres
• D. Part of muscular system, and provides elasticity

Answer 1

The correct option is A

Part of skeletal system, strongest of all fibres and responsible for skin strength

Collagen are the strongest of all fibres. These are arranged in parallel bundles, considered as part of bone, cartilage, tendons and ligaments. The collagens are also responsible for skin strength and elasticity, and its degradation leads to wrinkles that accompany aging.
