Bone: the organ
Skeletal muscle is inserting onto the periosteum of this fetal woven bone. Bone resorption, as well as bone deposition, is occurring on the external surface of this bone, as indicated by the presence of both osteoclasts and active osteoblasts in the osteogenic layer of the periosteum. 200x
