Skeletal Tissue
Across
- 3. cancellous
- 4. Hydroxyapatite crystals, 2/3 most of bone and provides hardness
- 7. Yellow bone marrow, triglycerides stored in adipose cells and serves as a potentioal chemical energy reserve
- 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
- 12. the structural framework of the body that supports soft tissues and provides attachment points for tendons of skeletal muscle
- 13. 1/3 the rest of bone matrix, and provides strength
- 14. Protects important internal organs, cranium protects the brain, vertyebrae protects the spinal cord, adn ribs protect lungs and heart
- 15. Release enzymes that digest the mineral components of bone matrix (resoprtion) and regulate blood calcium levels.
Down
- 1. Red bone marrow produces (Hematopoiesis); red blood cells, white blood cells, and platelets.
- 2. Calcium phosphate and collagen
- 5. consist of central (Haversian) canal with concentrically arranged lamellae, lacunae, osteocytes, and canaliculi
- 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.
- 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
- 9. bone-building cells. They synthesize extracellular matrix of bone tissue
- 11. Mature bone cells that exchange nutrients and wastes with blood.
- 16. cortical
