osteoclasts
osteoclasts are cells that dissolve bone cells.
osteoclasts
Osteoclasts break down bone (osteo-=bone, -clast=breaks) and osteoblasts build bone. (-blast=builder). This osteoclasts is on the surface of the bone. Usually breaking down and building up of bone is in equilibrium.
Osteoclasts are cells that degrade bone. Osteoblasts are the cells that build bonesSome bone cells deposit bone and some reabsorb bone tissue.
osteoclasts
Any of these changes may result if osteoblasts are more active than osteoclasts.
sites of active bone cell activity (living bones)
Bones.
both are more active because one builds and the other tears down
Osteoblasts and osteoclasts.
They absorb (or resorb) bone. Bone is active living tissue that is constant remaking itself. The osteoclasts break down and resorb old bone while osteoblasts lay down new bone to take its place.
Osteoclasts cut away the calcium from the bones.
osteoclasts
Ossification.
Osteoclasts degrade bone surfaces so that osteoblasts can produce new bone Also Osteoclasts realese calcium and phosphorus into the blood stream
When osteoclasts remove calcium salts faster than osteoblasts deposits them, it causes the bones to weaken.
