Consequently, mineralized bone tissues continually regenerate. Encased osteoblasts cannot add new bone tissue. However, they can transfer nutrients from the periosteum to the new bone tissue that they added to mineralized bone tissues. Because encased osteoblasts no longer function as bone tissue manufacturing osteoblasts, researchers call them osteocytes. Haversian Canals, Pre-Osteoclasts and Osteoclasts Osteoclasts locate in mineralized bone tissue and on the cortexes' endosteal surfaces.
Osteoclasts are many times larger than osteoblasts.
Consequently, without increasing bones' sizes or mineralizations, Haversian Canals strengthen bones against compression mechanical stresses. Endosteal osteoclasts cover forty percent of mineralized bone tissues' endosteal surfaces. Osteoclasts resorb mineralized bone tissues. Osteoclasts are very mobile. Every eighteen hours, osteoclasts contact entire endosteal surfaces.
