Across
  1. 3. cancellous
  2. 4. Hydroxyapatite crystals, 2/3 most of bone and provides hardness
  3. 7. Yellow bone marrow, triglycerides stored in adipose cells and serves as a potentioal chemical energy reserve
  4. 10. Central canals run longitudinally through bone, Around the central canals are concentric lamellae, Rings of calcified matrix (like the rings of a tree trunk),Between the lamellae are small spaces called lacunae which contain osteocytes,Between the lamellae are small spaces called lacunae which contain osteocytes
  5. 12. the structural framework of the body that supports soft tissues and provides attachment points for tendons of skeletal muscle
  6. 13. 1/3 the rest of bone matrix, and provides strength
  7. 14. Protects important internal organs, cranium protects the brain, vertyebrae protects the spinal cord, adn ribs protect lungs and heart
  8. 15. Release enzymes that digest the mineral components of bone matrix (resoprtion) and regulate blood calcium levels.
Down
  1. 1. Red bone marrow produces (Hematopoiesis); red blood cells, white blood cells, and platelets.
  2. 2. Calcium phosphate and collagen
  3. 5. consist of central (Haversian) canal with concentrically arranged lamellae, lacunae, osteocytes, and canaliculi
  4. 6. bone tissue stores several minerals and acts to serve as a reservoir of critical minerals, calcium makes up 99% of bodys content and is phosphorus.
  5. 8. resists the stresses produced by weight and movement where the components of compact bone are arranged into repeating structural units called osteons or haversian systems
  6. 9. bone-building cells. They synthesize extracellular matrix of bone tissue
  7. 11. Mature bone cells that exchange nutrients and wastes with blood.
  8. 16. cortical
