A protein secreted by osteoblasts during bone deposition is collagen. The collagen is put down in layers parallel to the long axis of the bone alternating with layers at right angles to the long axis of the bone, kind of in a cross-hatching pattern.

What are the osseous tissue cells that secret collagen?
Osteoblasts
Do osteocytes produce collagen fibers that span a break?
Osteoblasts
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 :)
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.
Do osteocytes become osteoblasts when they are completely surrounded by bony matrix?
As you know, osteoblasts secrete collagen and organic cmpounds upon which bone is formed. Osteoblasts are incapable of mitosis. As Osteoblasts release matrix materials around themselves, they become enveloped by the matrix and at this point differentiate into Osteocytes.
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.
Which cells secrete collagen and stimulate calcium phosphate deposition?
tissue
Can osteoblasts divide?
Yes, they divide, and as they divide, they create bone matrix and collagen fibers. As the osteoblasts become surrounded by the bone matrix, it hardens, enclosing the cells in a lacuna, transforming them into osteocytes. Osteocytes cannot divide.
The role of vitamin C in bone growth is that it?
is needed for proper collagen syntheis and is necessary for osteoblasts to create healthy bone matrix
What is formed through a process called ossification?
Bone is formed through a process called ossification. Osteoclasts are cells that release an acid which dissolves the collagen and mineral coating. Osteoblasts are cells that lay down new collagen. in ossification the osteoclasts and osteoblasts are involved in breaking down bone.. then forming bone which happens continuously in life
