  Bone Anatomy (General Osteology) In Anatomy of Bone (General Osteology) - Bone (os)  is an organ consisting of bone tissue, including cells and a solid intercellular substance, rich in collagen fibers and mineral compounds.  Bone contains 50% water, organic compounds (ossein), and inorganic substances (compounds of calcium, phosphorus, magnesium, etc.). Outside the Anatomy, the bone is covered with the  periosteum  - a thin connective tissue plate that firmly adheres to the bone . The periosteum contains many vessels, nerves, receptors. The outer layer of the periosteum is  fibrous , and the inner layer is  germ : young cells are formed in it -  osteoblasts , due to which the bone grows in thickness. In the case of fractures, a callus is formed from them. The outer layer of the bone   is represented by a plate of  compact substance , under which there is a porous  spongy substance , built of bone trab...

  In the Structure and properties of bones, we will discuss the Biochemistry & Physiology of Bones . which in the structure of bones we discuss how the bones made and which kind of matrix or I can say the substances used to form a bone. In the properties of bones, we discuss how bones work and which kind of physiological work they have. Structure and properties of bones The structure of Bones consists of a dense organic matrix, the strength of which is increased by the calcium salts impregnating it. The compact bone substance is approximately 30% matrix and 70% salt. In the newly forming bone , the percentages are shifted towards a greater representation of the matrix. Organic bone base - The organic matrix of the bone is 90-95% represented by collagen fibers, and the rest is a homogeneous gelatinous substance called the basic substance. The direction of the collagen fibers generally coincides with the direction of the tensile forces, which increases the ability of the...
