Osseous Tissue and Bone Structure
This chapter delves into the essential aspects of osseous tissue, including its roles in support, mineral storage, hematopoiesis, protection, and leverage. It examines the classifications and shapes of bones, as well as their structure and surface features. The text highlights the significance of calcium and other minerals in bone health, alongside the processes of endochondrial and intramembranous ossification. Additionally, it discusses the importance of bone remodeling and repair mechanisms, emphasizing the need for proper nutrient intake.

Osseous Tissue • Calcium salt matrix • Calcium phosphate • Calcium hydroxide • Calcium carbonate • Sodium • Magnesium • Fluoride • Collagen fibers http://www.israelnationalnews.com/News/News.aspx/132152 http://www.sciencephoto.com/media/301780/enlarge
Osseous Tissue • Osteoprogenitors • Osteoblasts • Osteocytes • Osteoclasts http://www.vetmed.vt.edu/education/curriculum/vm8054/labs/lab8/lab8.htm
Osseous Tissue: Spongy Bone • Trabeculae • Arranged along lines of stress • Red marrow • Hematopoiesis http://apbrwww5.apsu.edu/thompsonj/Anatomy%20&%20Physiology/2010/2010%20Exam%20Reviews/Exam%202%20Review/Ch%206%20General%20Terms%20&%20Bone%20Shapes.htm
Endochondrial Ossification http://eugraph.com/histology/crtbone/epipl.html
Bone Remodeling • Bone deposits where it is needed most • Move it or you lose it • Must ingest Calcium, Phosphate salts, Magnesium
