Bone is mixture of organic and inorganic componants. You have collagen fibres as organic and calcium salts as inorganic elements.
The inorganic portion of bone give hardness & durability but the organic portion of bone give flexibility
The inorganic part of the bone is dissolved, leaving the residual soft and flexible
The skeletal system is mainly responsible for bone structure. Bone cells will constitute the structure of the bone with osteoblasts facilitating the formation of bones.
collagenous fibers and inorganic salts.
calcium
inorganic salts
The matrix of the bone is portion of specialized connective tissue composed of intercellular, is contain an organic and inorganic materials 1- The organic material: collagen ( type I) 2- The inorganic material: calcium phosphate
Matrix
Bones contain hydroxyapatite, an inorganic salt.
Inorganic Calcium salts
No, potassium salts doesn't exist in bones.
the composition of bone matrix is 1/3 organic and 2/3 inorganic matter. The organic matter, synthesized by the osteoblasts (bone-forming cells), is collagen and proteins like glycosaminoglycan, proteoglycan, and glycoprotiens. the inorganic matter is mostly crystallized calcium phosphate salts and calcium carbonate, and a few other minerals. bone matrix is a composite which means it has characteristics of of the hard, strong inorganic matter and some flexibility and give from the collagen.
