Each myofibril is attached at either end of the muscle fiber, when sarcomeres shorten, the muscle fiber Shortens
Mechanism :
Myofibrils are components of the animal skeletal muscles that are made up of sacromeres. They perform the muscular contraction and relaxation via the sliding filament model.
To produce motion, A cross-bridge forms between actin and the myosin heads triggering shortening of the sacromere. This shortening of the sacromere results in the contraction of the muscle fibers, which the net effect can be seen to be a shortening of the fibers.

Answer:
Osteoclasts are the multinucleate bone cell that are responsible for absorbing bone tissue during healing and growth while osteoblasts are the cell responsbile for formation of new bones.
If there will be greater amount of osteoclasts than osteoblasts than the osteoclasts will allow calcium, present in bones to get dissolve which causes deformity of bones known as Osteoporosis (demineralization of the bones).
<em>Due to this the calcium level will increase in the kidney and can cause kidney stone as well.</em>
