Periosteum · Histology

What are 'Sharpey's fibers' (perforating fibers)?

  1. Elastic fibers that allow bone to bend
  2. Nerve fibers that transmit pain from the bone marrow
  3. Collagen bundles anchoring periosteum to bone
  4. Crystalline structures found in the hydroxyapatite
Show answer and explanation

Correct answer: Collagen bundles anchoring periosteum to bone

Sharpey's fibers are bundles of periosteal collagen fibers that penetrate deep into the outer circumferential lamellae of the bone matrix. They securely anchor the periosteum to the bone, especially at sites of tendon attachment.
