osteoid
Osteoblasts are the bone cells responsible for secreting osteoid, which is an unmineralized organic matrix that serves as the foundation for bone formation. Osteoid eventually becomes mineralized to form mature bone tissue.
Osteon is a structural unit of compact bone composed of concentric layers called lamellae surrounding a central canal, while osteoid is the unmineralized organic component of bone matrix made up of collagen and other proteins. Osteoid provides the framework for mineral deposition in the bone, while osteon represents the functional and structural unit for bone formation and remodeling.
Osteoblasts
bone (osseous) tissue
No. Cartilage is not another name for bone. It is hard tissue like bone, but is mostly made of collagen fibers, whereas bone is mostly made of extracellular matrix that contains calcium and phosphorus.
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.
Another name for Calcium salts in bone is hydroxyapatite. The extracellular mix in blood called plasma is the matrix.
Immature or matrix-depositing bone cells are osteoblasts. These cells are responsible for bone formation by secreting collagen and other proteins that make up the bone matrix. Osteoblasts play a crucial role in bone growth and remodeling.
The organic component of the bone matrix is primarily made up of collagen fibers, which provide flexibility and strength to the bone. Collagen is produced by bone cells called osteoblasts and helps in bone formation and repair processes.
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.
osteoblasts
Bone cells that liquefy the bone matrix and release calcium into the blood are called Osteoclasts. Immature or matrix depositing bone cells are called osteoblasts.
