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 are large cells that break down bone tissue
Cells that break down bone tissue are called osteoclasts. They are specialized cells responsible for resorption of bone tissue during bone remodeling and repair processes.
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.
Several cells have this function: the osteoclasts which break down bone and the osteoblasts which build bone.
Yeah, if your body is relaxed
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 are the cells responsible for breaking down bone tissue in a process known as bone resorption. They secrete acid and enzymes that degrade the bone matrix, allowing for the remodelling and repair of bones.
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 the cells responsible for breaking down and absorbing bone tissue through a process called resorption. They play a crucial role in bone remodeling and maintaining bone density.
Bone destruction is known as osteolysis. It is a process where bone tissue is broken down and reabsorbed, leading to a decrease in bone density and strength. Osteolysis can be caused by conditions such as osteoporosis, bone cancer, or inflammatory diseases affecting the bones.
