it is the formation of bones. This is the principal role of calcitriol. It requires both calcium and phosphate.
Deposition is to depose someone with sworn evidence. Sentences using this word are:- Janie's deposition was read to the court since she couldn't appear.- Sara was in the hospital so her mom read her deposition of the case to the lawyer.- Aaron's deposition proved that Corey was guilty of theft.
"Depose" is usually considered the root word.
In the context of physical sciences, deposition refers to the phase transition in which a gas transforms directly into a solid without passing through the liquid phase. The temperature at which deposition occurs is known as the deposition temperature and is specific to the substance undergoing the process. The deposition temperature is determined by the interplay of factors such as pressure, temperature, and the physical properties of the substance involved. It is crucial in various fields like materials science, chemistry, and geology for understanding processes like thin film deposition and mineral formation.

osteoblasts secrete matrix; bone deposition
Osteoblasts exemplify a positive feedback process in bone mineral deposition. When new bone is formed by osteoblasts, they release proteins that stimulate further osteoblast activity and mineral deposition. This creates a cycle where bone formation encourages more bone formation.
Peak bone mass occurs at ~30 years of age. Afterwards, bone loss starts to outpace bone deposition.
Osteoporosis is the condition in which bone resorption outpaces bone deposition, causing bones to become porous and brittle. This can increase the risk of fractures and other bone-related issues.
The deposition of calcium salts into bone tissue is called mineralization or calcification. This process helps to strengthen and harden the bones, making them more rigid and able to support the body.
Osteoblasts are responsible for secreting collagen and stimulating calcium phosphate deposition during the process of bone formation.
The addition of new bone on top of existing bone to increase bone thickness is called appositional bone growth. This process involves the deposition of new bone tissue on the outer surface of existing bones.
Specifically is the deposition of crystals of calcium phosphate that cause the replacing cartilage by bone, that is, chondrocytes are replaced by osteoclasts.
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.
To form into bone; to change from a soft animal substance into bone, as by the deposition of lime salts., Fig.: To harden; as, to ossify the heart., To become bone; to change from a soft tissue to a hard bony tissue.
When collagen is removed from the bone, the structure and strength of the bone are compromised. Collagen provides the framework for mineral deposition and helps to maintain the flexibility and resilience of bone. Without collagen, the bone becomes more brittle and prone to fractures.
