What secretes hydroxyapatite?
Hydroxyapatite is primarily secreted by osteoblasts, which are bone-forming cells. These cells synthesize and release the organic components of the bone matrix, including collagen, and facilitate the mineralization process that leads to the formation of hydroxyapatite crystals. This mineral is essential for providing strength and rigidity to bones and teeth.
What is osteoid and what is hydroxyapatite what are the functional qualities of osteoid and hydroxyapatite of bone tissue?
Osteoid is the organic component of bone tissue, primarily composed of collagen. Hydroxyapatite is a mineral component of bone tissue, providing strength and hardness to the bone. Osteoid contributes to the flexibility of bones, while hydroxyapatite enhances their structural integrity. Together, they give bones their rigidity and resistance to fractures.
What accounts for the majority of bone tissue matrix?
hydroxyapatite
Bone is somewhat flexible due to the presence of what choose 1 calcium or phosphates or collagen or hydroxyapatite?
Collagen is responsible for the flexibility of bones. The mineral composition of bones, primarily hydroxyapatite (a calcium phosphate), provides the bone with its strength and hardness.
What are the cells that produce organic matrix in bone?
The cells that produce the collagen and inorganic salts of bone matrix are osteocytes. Osteocytes maintain the protein and mineral content of the bone matrix. Osteogenesis is the production of new bone matrix.
What is responsible for the flexibility of bone?
The flexibility of bone is primarily due to its composition, which includes a combination of organic and inorganic materials. Collagen, a protein that provides tensile strength, constitutes a significant part of the organic matrix, allowing bones to bend slightly without breaking. Additionally, hydroxyapatite, the mineral component, contributes to the rigidity and strength of bones while still permitting some degree of flexibility. This unique structure allows bones to withstand various stresses and strains during movement.
How would removing hydroxyapatite from bone matrix affect the physical properties of a bone?
By removing hydroxyapatite from bone matrix the properties of the bone would become more "rubbery" or flexible. Hydroxyapatite is the natural occurring form of calcium. By taking the calcium out of a bone, the bone would be more flexible because the collagen remains.
What does Mineral salts in bones do?
The mineral in bones is the hydroxyapatite - Ca10(PO4)6(OH)2.
What is the role of the bone salts and organic matrix in making bone both hard and flexible?
Bone salts (calcium, mainly) lend hardness; the protein-rich organic matrix permits some flexibility
What element composes the bone matrix?
Bone is composed of a mineral called hydroxyapatite. The chemical formula for hydroxyapatite is Ca10(PO4)6(OH)2. Thus, the elements in bone matrix would be calcium, phosphorus, oxygen and hydrogen.
What is responsible for bone structure?
An organic molecule is a molecule which contains the element carbon. An inorganic molecule is the opposite. Almost all of the molecules that are inside the human body would be classified as organic molecules.
What is another name for calcium salt in bone?
Another name for Calcium salts in bone is hydroxyapatite. The extracellular mix in blood called plasma is the matrix.
