BIOL 260 Chapter Notes - Chapter 7.2: Myeloid Tissue, Humerus, Ultimate Tensile Strength
Document Summary
7. 2 histology of osseous tissue: types of bone cells, 1. ) osteogenic cells: stem cells that develop from embryonic mesenchyme and then give rise to most other bone cell types. They multiple continually, and some go on to become the osteoblast: 2. ) osteoblasts: are bone-forming cells. This apparently stimulates sensory cilia on the osteocytes and induces the cell to secrete signals that regulate bone remodeling adjustment in bone shape and density to adapt to stress: 4. This increases the cell surface area and thus enhances the efficiency of bone resorption: often reside in pits called resorption bays that they have etched into the bone surface. The central and perforating cnaals are lined with endosteum: collagen fibers corkscrew down the matrix of a given lamella in a helical arrangement like the threads of a screw. The helices coil in one direction in one lamella and in the opposite direction in the next lamella.
