Bones break whenever an event supplies adequate force which exceeds the bone's resiliance to that stress. Bending, twisting, compression, and impact forces can provide instantaneous energy to do this but lower energies applied over longer periods, i.e., repetitive stress, can contribute. Vibrations, if of sufficient duration and strength, can exceed the ability to absorb energy successfully. as well. Wherever the force concentrates is where the break usually occurs.
We know that certain fracture/breaks are more problematic than others. Breaks in the femur neck are almost impossible to heal without surgical pinning or even complete replacement, whereas breaks in the ribs or clavicles are typically left alone to heal normally and are rarely treated surgically unless they are compounded fractures and threaten to poke inward towards the lungs.
osteoclasts
When osteoclasts break down bone that is called resorption.
Osteoclasts are large cells that break down bone tissue
Csteoclasts
Osteoclasts break down bone and osteoblasts build up bone.
Osteocytes grow bone (lay it down) and osteoclasts break down bone. So there will be many more cells laying down bone (osteocytes) in primary bone.
Osteoclasts
Osteoclasts
Bone is broken down and built up all the time. This occurs on the surface of all bone types. About 10% of bone is replaced each year. Osteoblasts build bone. Osteoclasts break it down. Calcium is needed for this process.
The name of the cell that breaks down bones is called the osteoclast.The cell that builds bones is called the osteocyte.The break down bone cells are usually remodeled by the connective tissue that are found on the surface of the bone.
Several cells have this function: the osteoclasts which break down bone and the osteoblasts which build bone.
Yeah, if your body is relaxed
Osteocytes are bone cells. Special ones that build bone are called osteoblasts (blast=build) and ones that break down bone are called osteoclasts (clasts=break).
