Themajority of this tissue is matrix. Tendons connect muscle to bone. Ligamentsconnect bone to bone. Bone Microanatomy Cells of bone proper include osteocytes,osteoblast, and osteoclasts. Other cells found in bone include chondrocytes,nerve cells of the periosteum, blood cells in the marrow, and fat cells inyellow marrow of the diaphysis.
Osteocytes are bone maintenance cells and arefound in bone spaces called lacunae.
These cells control mineral storage inbone tissue. Osteoblasts are bone forming cells thateventually become encased in secreted bone matrix and then differentiate toform osteocytes. These cells are very active during bone formation in a fetusand during childhood, and during fracture repair. Osteoclasts are bone destroying cells,important in bone remodeling during bone growth and during fracture repair andremodeling. The cartilage is then remodeled into bone in a similar fashion to the way thatcartilage in the epiphyseal plates of growing bone is remodeled as bone grows.
