When muscle and bone are not used, they become weaker. This is called atrophy.
atrophy
osteocytes
The muscles begin to become atrophied from disuse.
The muscle has been inactive while it was in the cast, therefore, it has weakened from disuse.
As soon as six hours after takeoff NASA has found bone loss and muscle atrophy from disuse in their orbiting astronauts. When they return home this effect is reversed and they regain both muscle and bone that they lost in space.
The muscle atrophies after extended periods of disuse.
In type of excercise
Atrophy is progressive weakening and size reduction of muscle tissue which is usually the result of disease or disuse.
Cells comprise bone and muscle, they do not have bone and muscle in them.
