What are the bone cells responsible for synthesizing and depositing bone material called?

Osteoblasts are the cells primarily responsible for synthesizing and depositing bone material. They play a crucial role in bone formation by producing and secreting the components of the bone matrix, primarily collagen and other proteins, which then mineralize to form hard bone tissue. These cells are vital for growth, maintenance, and repair of bones.

The roles of other cell types provide context to the function of osteoblasts: Osteoclasts, for example, are involved in the resorption of bone—breaking down bone tissue for calcium release into the bloodstream. Chondrocytes are associated with cartilage rather than bone and are responsible for producing and maintaining cartilage. Osteocytes, which are mature bone cells derived from osteoblasts, help maintain bone tissue but do not actively synthesize new bone material. This distinction highlights the specific and essential role osteoblasts play in bone health and development.
