What happens When an osteoblast becomes surrounded by calcified extracellular material?
former osteoblasts that have become surrounded in bone matrix that is calcified
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.
Bony lump on forehead believed to be calcified bone How is this removed?
First of all, who is it that 'believes' this lump on your forehead is 'calcified bone'? If it was you or other persons who don't have a medical license, see a doctor. If your doctor believes the lump to be calcified bone, ask your doctor what should be done to remove it.
Is the bone matrix non living?
The matrix of the bone (calcified hydroxyapatite) is non-living; the living part of the bone are the cells (osteoblasts, osteocytes, osteoclasts) and the periosteum, a tough membrane that covers the bone and allows tendons and ligaments to attach to the bone.
What does calcified opacities mean?
Opacification means to become opaque - not see-through/transparent.
What is a serious bone disease characterized by excessive loss of both calcified matrix and collagenous fibers from bone?
Osteoporosis is a serious bone disease characterized by excessive loss of both calcified matrix and collagenous fibers, leading to weaker, more brittle bones that are at a higher risk of fractures. It is often associated with aging, hormonal changes, and nutritional deficiencies.
what is the main organic substance found in bone?
A typical bone has an outer layer of hard or compact bone, which is very strong, dense and tough. Inside this is a layer of spongy bone, which is like honeycomb, lighter and slightly flexible. In the middle of some bones is jelly-like bone marrow, where new cells are constantly being produced for the blood.
Definition of calcified opacity?
Calcified opacity is a radiological word that means there was an opaque area in rays that could not penetrate and just appear like a bone. This also means that the light does not pass though the material being described.
What is the function of the organic material in bone?
The bone matrix is made of 35% organic material and 65% inorganic materials. The organic material gives bone flexibility & strength.
What is organic in a bone?
Everything in a bone is organic. The word organic refers to something coming from something that is naturally occurring. Since bones are naturally occurring in animals, they are completely organic.
What is spongy bone also called?
spongey bone is flexible but can break very easily. Isnt science fascinating.
What are the organic parts of a bone?
Osteiod is the organic part of the bone. It consists of collagen fibers for framework, glyco proteins and proteoglycans.
