The periosteum consists of … Seventy-eight sagittal sections from the fore and hind limbs of replicon-infected mice were screened for GFP-positive cells. To prevent the bone from becoming unnecessarily thick, osteoclasts resorb the bone from the endosteal side. While the endosteum is present inside the bone cavity, the periosteum is the firm and durable part present outside the bone. Endosteum can perform various functions in your body such as.
