Bone and Cartilage Physiology · Zoology

The 'organic' part of the bone matrix, which provides flexibility and tensile strength, is primarily composed of:

  1. Hydroxyapatite
  2. Calcium carbonate
  3. Collagen fibers
  4. Magnesium salts
Show answer and explanation

Correct answer: Collagen fibers

Bone matrix is a composite material; the organic component (osteoid) is about 90% collagen. This prevents bones from being too brittle and allows them to resist twisting and stretching forces.
