Several types of cells are involved in the maintenance and function of spongy bone: - [Osteoblasts](https://) are responsible for the synthesis of bone matrix and the formation of new bone. - [Osteocytes](https://), which are mature osteoblasts embedded in the bone matrix, maintain the bone tissue. - [Osteoclasts](https://) are large, multinucleated cells that break down bone tissue, playing a crucial role in bone resorption and remodeling. - [Bone marrow cells](https://), including hematopoietic stem cells, support the production of blood cells within the spongy bone cavities.
