|
Canaliculi |
"Little Canals" that connect lacunae and osteocytes to each other |
|
|
Osteoclast |
Cells that act to reabsorb or breakdown bone tissue |
|
|
Lamellae |
Concentric rings or tubes of bone matrix |
|
|
Chondrocyte |
Mature cartilage cell (usually trapped in lacunae) |
|
|
Lacunae |
A small cavity (often houses cartilage or bone cells) |
|
|
Endosteum |
A cellular membrane lining the spicules, trabeculae, canals, and medullary cavity of bone |
|
|
Chondroblast |
Immature cartilage cell (responsible for matrix production) |
|
|
Haversian (central) canal |
Canal lined with endosteum to supply blood vessels, lymphatics and nerve to bone |
|
|
Ossification |
Process of bone formation |
|
|
Mesenchymal cell |
Embryonic connective tissue cell (gives rise to all other CT) |
|
|
Interstitial Growth |
Cartilage growth due to mitosis of chondrocytes (may occur along epiphyseal plate of long bone to increase bone length) |
|
|
Appositional Growth |
Growth of bone or cartilage due to the addition of bony matrix or cartilage to the outer surface (just under peroisteum) (increase in width) |
|
|
Osteoblast |
Immature, matrix producing bone cell |
|
|
Periosteum |
A thick, fibrous connective tissue layer surrounding the entire external surface of bone, with the exception of the articular surface. |
|
|
Osteon |
(Haversian System)- The functional and structural unit of compact bone. They consist of tiny structural "pillars" made of concentric rings or tubes of bone |
|
|
Osteocyte |
Mature bone cell (usually trapped in lacunae) |
|
|
Spicules of Bone |
Tiny, needle-like bits of bone (connect to form trabeculae) |
|
|
Hypertrophy |
Enlargement of cells |
|
|
Osteoid |
Non-living bone tissue made of calcium and phosphate |
