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.

Both the cardiac muscle and nervous tissue in the brain and spinal cord have no functional regenerative capacity.
A tissue is a group of similar cells that perform a common function.

Hydroxyapatite
The organic component of the matrix of bones
§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 :)
The matrix of the bone is portion of specialized connective tissue composed of intercellular, is contain an organic and inorganic materials 1- The organic material: collagen ( type I) 2- The inorganic material: calcium phosphate
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.

bone is made up of living tissue.
Both the cardiac muscle and nervous tissue in the brain and spinal cord have no functional regenerative capacity.

It is the tissue which surrounds and supports the actually functional lung tissue
