OSTEOLOGI DASARdr. A. Arief Munandardr. Yuli FitrianaTujuan KuliahMengetahui secara umum susunan tulang manusiaMengetahui susunan tulang secara anatomi, fisiologi dan patofisiologis

FungsiMemberikan bentuk tubuhMenunjang berat badanTempat perlekatan ototPelindung organ tubuh yang lunakPergerakan (sendi)Membentuk sel-sel darahPenyimpanan zat (Ca, P, Mg)Kerangka ManusiaKerangka tersusun oleh:Tulang rawan (kartilago)Tulang keras (osteo)

STRUCTURE OF BONE

The matrix of boneThe cells of Mature boneTHE MATRIX OF BONEWater (25%)Organic Constituent (~25%)Inorganic Constituent (~50%)

THE CELLS OF BONEOsteogenic cells- stem cells. Osteoblasts- bone building cells, secrete matrix & collagen fibers.Osteocytes- mature bone cells that no longer secrete matrix.Osteoclasts- bone digestion
