Unformatted text preview: DEFINITIONS • Mature, lamellar bone tissue: organized structure produced by the repeated addition of uniform lamellae to the bone surfaces during appositional growth • Haversian systems: with canals and canaliculi provide nourishment to compact bones • Haversian canals: also known as secondary osteons; free canals in the compact bone that contain blood and lymph vessels and nerves and marrow • Hemopoietic: related to production and development of red blood cells • Volkmann’s canals: pierce the bone tissue obliquely and at right angles from the periosteal and endosteal surfaces to link the Haversian canals, creating a network that supplies blood and lymph to the cells of the long bones • Lacunae: small cavities found within each lamella, each lacunae harbors an osteocyte or multiple chondrocytes. • Osteocyte: living bone cells differentiated from osteoblasts. • Canaliculi: minute fluid filled channels that radiate from the centrally placed Haversian canal to the lacunae in succeeding lamellae or from one lacuna to others to provide nourishment to osteocytes •...
