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.
Distinguish between collagen and elastin?
Collagenous fibers are the white fibers consisting of the protein collagen, common in connective tissues, including bone matrix as on the other hand Elastin fibers are stretchy yellow connective tissue fibers consisting of the protein elastin.
What are the parts of bone matrix?
bone matrix the intercellular substance of bone, consisting of collagenous fibers, ground substance, and inorganic salts.
What is a serious bone disease characterized by excessive loss of both calcified matrix and collagenous fibers from bone?
Osteoporosis
What are the 3 parts common to all connective tissues?
The features that all connective tissues share in common isFibroblasts. Fibroblasts are typically responsible for the formation of the acellular matrix.Connective tissues that have this common trait include bone and cartilage, but exclude blood (which meets all the connective tissue criteria) and loose connective tissue.^True, but I think what he's looking for is this:o Common origin - all arise from mesenchyme (an embryonic tissue)o Degrees of vascularity - cartilage = avascular, dense connective tissue = poorly vasculated,o Extracellular matrix - comprised of nonliving extracellular matrix
What protein fibers are bone matrix composed of?
collagen

What tissue is rich in Hydroxyapatite?
Hydroxyapatite is composed mainly of calcium phosphate and is found in the interstitial fluid. It automatically crystalizes around the collagen fibers to form the hard matrix of the bone.
What do protein fibers provide bone with?
strength and flexibility

Which organic protein is responsible for the bone matrix that hydroxyapatite binds to?
Collagen
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.
What gives bones strengths and hardness?
Collagen fibers within the bone matrix.
What is the role of bone salts and the organic matrix in making the bone both hard and flexible?
Bone salts (calcium, mainly) lend hardness; the protein-rich organic matrix permits some flexibility
