Osteocytes residing in lacunae of osteons of healthy compact bone are located quite a distance from the blood vessels in the central canals, yet they are well nourished. How can this be explained?
Because of the constant exchange of blood calcium and bone calcium, the concentration of calcium ions in the blood and tissue is very steady. Describe the process of calcium mobilization in bone tissue.
What type of cellular process is most likely the mechanism employed by osteoblasts to release bone matrix until they are surrounded by it?
