Microscopic Structures in Bone Tissue Quiz

Compact bone contains osteocytes in lacunae arranged around central canals.

Osteoclasts break down the bone matrix during remodeling.

Osteoblasts are responsible for bone formation and mineralization.

Canaliculi connect adjacent lacunae in bone tissue.

Spongy bone contains trabeculae and provides strength while reducing weight.

Osteoclasts are responsible for bone resorption and breakdown.

Spongy bone contains trabeculae and is highly vascularized.

Haversian canals contain blood vessels and nerves in bone tissue.

Collagen is the main organic component of bone tissue.

Endochondral ossification is the process of cartilage being replaced by bone tissue during development.

Parathyroid hormone (PTH) regulates calcium levels in blood and bone tissue.

Intramembranous ossification is bone tissue formation from mesenchymal cells.

Vitamin D is essential for calcium and phosphorus absorption in the intestine.

Canaliculi contain cytoplasmic extensions of osteocytes connecting neighboring cells.

Bone remodeling involves osteoclasts removing old tissue and osteoblasts depositing new tissue.

Calcium phosphate crystals provide hardness and resistance to compression in bone tissue.

Calcitonin inhibits bone resorption by osteoclasts and promotes bone formation by osteoblasts.

Osteoclasts break down bone tissue during remodeling.

Resorption is the process of breaking down bone tissue to release minerals into the blood.
