What is osteoid and what is hydroxyapatite what are the functional qualities of osteoid and hydroxyapatite of bone tissue?
osteoid is the primary semisolid bone matrix that is secreted by osteoblast. hydroxyapatite is a crystalized mineral that surrounds collagen fibers of the matrix to solidify bone.
The term osteoid refers to the organic part of the matrix of compact bones?
Yes. Osteoid is the organic bone matrix secreted by osteoblasts.
Does osteoid tissue contain proteoglycans?
YEs, it does..
What is the name of the unmineralized bone matrix?
osteoid
Is orgainic bone matrix called osteoid?
Yes.
What bone cells secrete osteoid?
fanny, bum, poo
What is Osteoid tissue?
The organic component of the matrix of bones
Describe the process of new bone formation in an adult bone use the terms osteoid seam and calcification front?
The adult process of new bone formation by calcification front is where the new bone formation meets the osteoid seam. . Calcification front is the dividing line where the osteoid seam meets older mineralized bone.
What are the steps in bone deposition?
§The initial stage in bone production is the secretion of collagen molecules and ground substance by osteoblasts. §The collagen monomers polymerize rapidly to form collagen fibers. §The resultant tissue becomes osteoid §As the osteoid is formed, some of the osteoblasts become entrapped in the osteoid and become quiescent osteocytes. §Within a few days after the osteoid is formed, calcium salts begin to precipitate on the surfaces of the collagen fibers. §The precipitates first appear at intervals along each collagen fiber, forming minute nidi that rapidly multiply and grow over a period of days and weeks into the finished product, hydroxyapatite crystals. hope thats good enough :)
Which type of bones cells produce collagen?
Osteoblasts. They make a protein mixture known as osteoid which mineralizes to become bone. These osteoids are primarily composed of Type I collagen.
What is osteiod?
An Osteoid is organic matrix composed of glycoproteins, collagen fibres. They are formed prior to maturation of the bone tissue. Osteoblasts produce ostgeoids. Bone is constantly reshaped by Osteoblasts which build bone.
What cell responsible for early stage of endocondral ossification?
Osteoprogenitor cells are undifferentiated cells found in the perichondrium. These later become osteoblasts - which secrete osteoid (part of the bone matrix). Chondrocytes are responsible for calcification.
