Document Summary

Functions of bones and the skeletal system: support, protection, assistance in movement, mineral storage and release, blood cell production, triglyceride storage, hemopoesis production of blood cells that occurs in red bone marrow. Histology of a spongy bone bone interior: osteoclasts lined along osteoblasts to form trabeculae, red bone marrow, ends of long bones, inside flat bones, bones of the skull, ribs. Draining blood from bone: nutrient veins, metaphyseal/epiphyseal veins, periosteal veins. Intramembranous ossification: simpler process than endochondral ossification, examples: flat bones of the skull, involves a 4-step process of flat bones; diploe, 1. Development of ossification center: osteoblasts secrete organic extracellular matrix: 2. Calcification: calcium and other mineral salts are deposited and extracellular matrix calcifies (hardens: 3. Formation of trabeculae: extracellular matrix develops into trabeculae that fuse to form spongy bone: 4. Development of periosteum: mesenchyme at the periphery of the bone develops into the periosteum.
