Chapter 6 -bones Test Flashcards
Solid densely packed,in shaft, strong protective
Compact bone
Functions of bones
Storage of calcium/phosphate
Loosely packed
Spongy bone
Shaft of bone
Diaphysis
End of bone (proximal/distal)
Epiphysis
Area where growth occurs between shaft and ends
Metaphysics
Center of shaft
Marrow cavity
On the ends of bones (reduces friction)
Articulate cartilage
Mostly found in kids makes blood
Red bone marrow
Found in adults makes fat when formate
Yellow bone marrow
Study of cells
Histology
Solid calcium phosphate college fibers
Matrix
Bone cells
Osteocytes
Compartments that house osteocytes
Lacunae
Concentric rings around blood vessels
Lamellar
Vertical pathway for blood vessels
Haversain canal
Horizontal pathway for blood vessels
Villanova canal
Connect one lacunae to annother
Canaliculi
Outer protective layer of bone
Periosteum
Ground substance (strength)
Calcium phosphate
Strong flexible fibers
Collogwn
Bone cells
Osteocytes
Make new bone tissues
Osteoblasts
Process of forming new bone
Osteogenesis
Bone stem cells
Osteoprogenitor
Break down bone tissue
Osteoclasts
Process of breaking bone tissue down
Osteolysis
Shaft
Compact bone
Ends
Spongy bone
Struts form spongy bone make up
Trabeculae
Functions of cells
Separate from other tissues
Pathway for blood vessels
Helps bone grow and repair
Inner protective lining on marrow cavity
Endosteum
Process of bones hardening
Ossification
Flat bone formation
Intramembranous
Long bone formation
Endochidral
Occurs the outside surface
Appositional growth
Process of replacing bone tissue throughout a life time
Remodeling
Parathyroid glands
Increase osteoclasts
Increased absorption of calcium
Decrease rate of excretion by the kidneys
Fracture repair
- )hematoma (blood clot forms)
- )external callus forms
- )spongy bone forms
- )compact bone replaces spongy bone
- )Callus is removed overtime

Decrees in ossification of bone
Osteopenia
