1) Microscopic inspection of hyaline cartilage would show prominent parallel bundles of collagen fibers.
2) In appositional growth, chondrocytes within cartilage divide and secrete new matrix.
3) As a person ages, some calcium phosphate crystals are deposited within cartilage, leading to a condition called calcified cartilage.
4) Cartilage is strong in resisting twisting and bending but weak in resisting tension and compression.
5) A fracture in which the bone breaks cleanly but does not penetrate the skin is a compound fracture.

10) Osteocytes, residing within lacunae, are connected via canaliculi.
11) Circumferential lamellae occur around the entire outer and inner surfaces of compact bone, and they are considered remnants of old osteons that have been disrupted by bone remodeling.
