Osteoblasts
Osteoblasts
Osteoblasts are the cuboidal cells responsible for synthesizing the organic components of the bone matrix, including collagen and proteins. They play a key role in bone formation and repair by producing and mineralizing the organic matrix that serves as the framework for bone tissue.
Cells need to synthesize new organic components to grow, repair damaged tissue, and maintain homeostasis. These components include proteins, lipids, carbohydrates, and nucleic acids that are essential for various cellular functions and structures. Without the ability to synthesize new organic components, cells would not be able to function properly and would eventually die.
Hydroxyapatite is primarily secreted by osteoblasts, which are bone-forming cells. These cells synthesize and release the organic components of the bone matrix, including collagen, and facilitate the mineralization process that leads to the formation of hydroxyapatite crystals. This mineral is essential for providing strength and rigidity to bones and teeth.
an osteocyte is a bone cellan osteoblast is specific to the building/production of new boneOsteocytes are mature bone cells that maintains the bone matrix. Osteoblasts are immature bone cells that secrete organic components of matrix.
Osteoblasts
it is where blood cells are manufactured
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.
The suffix "-blast" indicates cells that produce the matrix of connective tissue. These cells are responsible for synthesizing and secreting the components that make up the extracellular matrix in connective tissues.
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
The two main components of all tissues are cells (which are the basic structural and functional units) and the extracellular matrix (which is the material that surrounds and supports the cells). Together, cells and the extracellular matrix give tissues their structure and function.
Cells in lacunae allow for the exchange of nutrients and waste products with the surrounding extracellular matrix. They also help maintain tissue structure and function by secreting and maintaining the matrix components.
