 fibrous membrane rich in blood vessels that envelopes the bone, except at the articular surfaces; it contributes especially to the bone’s growth in thickness.

 dense bone tissue composed of osteons, which resist pressure and shocks and protect the spongy tissue; it forms especially the diaphysis of the long bones.  Osteon - elementary cylindrical structure of the compact bone made up of four to 20 concentric bone plates that surround the Haversian canal.

 Elementary cylindrical structure of the compact bone made up of four to 20 concentric bone plates that surround the Haversian canal.  Lengthwise central canal of the osteon enclosing blood vessels and nerves. Osteon

 Tissue made of bony compartments separated by cavities filled with bone marrow, blood vessels and nerves  This structure gives bones their lightness.

 Cylindrical central cavity of the bone containing the bone marrow  Encloses lipid-rich yellow bone marrow  Soft substance contained in bone cavities,  producing blood cells;  marrow is yellow in the long bones of adults. Bone Marrow

 Transverse canals of the compact bone enclosing blood vessels and nerves;  Connect the Haversian canals with each other and with the medullary cavity and the periosteum Blood Vessel  Channel in the bone through which the blood circulates, carrying the nutrients and mineral salts the bone requires

 Smooth resistant elastic tissue covering the terminal part of the bone where it articulates with another bone  it facilitates movement and absorbs shocks

 Link bones  Sheets of strong, fibrous connective tissue  Identical to tendons in muscular system  Only difference is there function  Ligaments attach bone to bone and tendons attach muscle to bone

 Cartilage  Smooth resistant elastic tissue covering the terminal part of the bone where it articulates with another bone  it facilitates movement and absorbs shocks  Synovial Fluid
