What are the organic components of bone matrix?

What are the organic components of bone matrix?

Bone matrix (also known as osteoid) consists of about 33% organic matter (mostly Type I collagen) and 67% inorganic matter (calcium phosphate, mostly hydroxyapatite crystals).

What are the main components of the bone?

bone, rigid body tissue consisting of cells embedded in an abundant hard intercellular material. The two principal components of this material, collagen and calcium phosphate, distinguish bone from such other hard tissues as chitin, enamel, and shell.

What organic and inorganic components make up our bones?

As described above, by volume, bone consists of 40% inorganic component (hydroxyapatite), 25% water and 35% organic component (proteins) [1,2,12]. 90% of the organic component are collagen type I and the remaining 10% noncollagenous proteins.

What is organic component of bone?

The mineralized matrix of bone tissue has an organic component of mainly collagen called ossein and an inorganic component of bone mineral made up of various salts. Bone tissue is a mineralized tissue of two types, cortical bone and cancellous bone.

What are cellular components of bone?

Bone is composed of four different cell types; osteoblasts, osteocytes, osteoclasts and bone lining cells.

What is organic bone?

Organic part of bone is a protein Ossein and Collagen fibres. Inorganic part of bone is mainly Calcium Phosphate. The inorganic mineral is responsible for its hardness.

Which is an organic component of bone quizlet?

Bone has both organic and inorganic components. Its organic components include the cells (osteogenic cells, osteoblasts, osteocytes, and osteoclasts) and osteoid (os′te-oid), the organic part of the matrix.

What are the two components of bone composition?

What are the inorganic components of bone?

The organic component of the bone matrix includes the collagen and ground substance whereas the inorganic component is the inorganic bone salts, mainly the hydroxyapatite. The collagen and ground substance form approximately 25% of the bone mass. Collagen, though, is the predominant organic component.

What is the function of the organic matrix in bone?

An organic matrix of a bone is 34%, while 90% of the bone protein has a triple helical structure with less non-collagenous proteins. In addition to that, an inorganic and natural connection in the bone matrix enhances bone resorption, which occurs in the intracellular and extracellular phase.

What substance is bone composed of?

Bone is a connective tissue largely composed of an organic protein; collagen and the inorganic mineral hydroxyapatite, which combine to provide a mechanical and supportive role in the body (Smith et al. 1983:211).

What is the function of inorganic salts in bone?

The inorganic salts are mainly responsible for rigidity and hardness, which make bone resist compression caused by the forces of weight and impact. The organic connective tissue portion of the bone makes it resilient and thus the bone can afford resistance to tensile forces. In strength bone is comparable to iron and steel.
