Document Summary

The vertebrate skeleton: variation of a common theme. Storage: minerals (calcium, phosphorus) within the matrix of bone tissue, energy reserve (adipose) within the yellow marrow of long bones. Blood cell production (within red marrow of spongy bone tissue) Bone is organized into different regions and contain various biologically active structures (nervous tissue, vascular structure). In addition to osteocytes, the mature bone cells found within the matrix of bone tissue, there are three other cells that are associated with bones: Osteoprogenitor cells: derived from mesenchymal cells, can undergo mitosis, mature into osteoblasts. Osteoblasts: responsible for osteogenesis (create bone tissue, promote bone growth), mature into osteocytes. Osteoclasts: derived from embryological wbcs, secrete enzymes for osteolysis (resorption of bone tissue), necessary for calcium homeostasis. Ossification: process of converting other tissues to bone; begins around week 6-8 of embryological development. Two types of ossification processes occur during embryological formation: Forms flat bones of skull, mandible, clavicle. Replacement of mesenchymal membrane with osseous tissue.
