Osteoblasts build bone andmature into
Cartilage Osteocytes whichhelpmaintainbone
Multinucleated osteoclasts breakdownbone
Semi rigid connective tissue

Chondroblast build Osteocytes Helpmaintainbone
Produces cartilage matrix
Osteoclasts breaksdownbone
Chondrocytes
cartilage cell surroundedbymatrix
Osteoblasts
Are cuboidal to columnar cells found in the
inner Periosteum Endosteum
Derived from flattened Osteogenic cells
Performbonedepositionprocess which thenthey secrete the
organic matrix aid in formation of the inorganic matrix
Become surrounded and trapped
by secreted bone matrixin Lacuna
Oncethis happens becomes
osteocytes
Secrete chemicals requiredfor maintaing ECM
Recruit osteoblasts to build up bone undertension
