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 makes up the organic and inorganic portions of matrix?
The two major components of the matrix are ground substances and fibers. Fibers can be broken into the classes; collagen, elastic and reticular fibers.
Is Bone matrix contains no fibers?
No, bone matrix does contain fibers. Specifically, it contains collagen fibers, which provide tensile strength and flexibility. The bone matrix is primarily composed of organic components, mainly collagen, and inorganic mineral components, such as hydroxyapatite, which contribute to its rigidity and overall structure. These fibers play a crucial role in the formation and function of bone tissue.
What is Osteoid tissue?
Osteoid tissue is an organic component of bone that forms before it gets mineralized into hard bone tissue. It consists mainly of collagen and provides a framework for mineral deposition, contributing to the strength and flexibility of bones.
What are the primary components of the extra cellular matrix?
red blood cell molocules
What cells synthesize the organic components of the bone matrix?
Osteoblasts
What is the name of cells that synthesize organic components of the bone matrix?
Osteoblasts
What breaks down the calcified matrix and are replaced with bone-buildings?
The process that breaks down the calcified matrix is primarily carried out by cells called osteoclasts. These cells resorb bone tissue by dissolving the mineral components and degrading the organic matrix. Once the calcified matrix is broken down, it is replaced by bone-building cells known as osteoblasts, which synthesize new bone matrix and facilitate bone formation. This dynamic process is essential for bone remodeling and maintenance.
What are the three primary components of goals?
Organic resin matrix, Inorganic filler particles, coupling agent
What organic and mineral components of the bone matrix are continually being recycled and renewed through the process of?
REMODELING

How would increasing the proportion of organic molecules to inorganic components in the bony matrix affect the physical characteristics of bone?
Increasing the proportion of organic molecules in the bony matrix would likely make the bone more flexible and less brittle. This is because organic molecules provide elasticity and strength, while inorganic components like minerals provide hardness and rigidity. Balancing these components is important for maintaining the structural integrity of bone.
What are osteoblasts and osteocytes?
an osteocyte is a bone cellan osteoblast is specific to the building/production of new boneOsteocytes are mature bone cells that maintains the bone matrix. Osteoblasts are immature bone cells that secrete organic components of matrix.
Is Bone matrix contains no fibers?
No, bone matrix does contain fibers. Specifically, it contains collagen fibers, which provide tensile strength and flexibility. The bone matrix is primarily composed of organic components, mainly collagen, and inorganic mineral components, such as hydroxyapatite, which contribute to its rigidity and overall structure. These fibers play a crucial role in the formation and function of bone tissue.
The term osteoid refers to the organic part of the matrix of compact bones?
Yes. Osteoid is the organic bone matrix secreted by osteoblasts.
What two vitamins are needed for calcification process to synthesize bone matrix?
The two "vitamins" are A and C.
