Shaft
Periosterum
Outside tissue that wraps bone
Sharpey’s Fibers
“Glues” periosterum to bone
Osteoblasts
Build bone
Osteoclasts
Degenerate bone
Epiphysis
Ends of bone
Epiphyseal Line
Divides head from shaft
Growth plate
Yellow marrow
Found in the shaft of bone
Mostly adipose
Red Marrow
Found in heads of bone
Generates blood cells
Endosteum
Inside lining of bone
Central (Haversian) Canal
Central channel
Everything grows around this channel
Osteocytes
living bone cell
Lacunae
Open spaces where osteocytes live
Lamellae
Concentric rings
Osteon or Haversian System
Channels with nerves, arteries etc and their concentric lamellae
Each “tree”
Canaliculi
Tiny blood vessels that connect to lacunae for nutrients
Perforating (Volkmann’s) Canals
Connects osteons to one another
