The muscles that appear striped in microscope images are called skeletal muscles. All skeletal muscles are attached to bones of the body.
Your bones are solid and fixed - they cannot move by themselves because they have no flexibility. Your muscles are used to move your bones because each muscle can contract or relax - get shorter or longer - and therefore cause the bones to move.
Tendons hold muscle to bone. (Ligaments hold bone to bone.)
Muscles never "push"; they can only "pull".The only power that muscles have is to contract or relax. When they contract, they pull. Most bones have two or more sets of muscles, and each muscle pulls in one direction; in sets, the muscles can work together or oppose each other, which account for all the actions that an animal or person can perform.
What bones move when you smile? No bones at all move! Your spirit moves your mouth and your future ghost moves all other parts of your body. The spirit knows how to show emotions so it can smile for you! The future self knows what you have done so it knows what the rest of your face looks like when it smiles! So, no bones move!
Well, whenever you move, your muscles pull on your bones (bones are connective tissue). Bones act as levers for muscles. When you exercise, both muscles and bones are being used, and therefore are getting stronger. It might be very slight, but it's still there. I'm not sure about this part, but I think that in certain cases, bones will give up some of their calcium to give to muscles in order to detach myosin heads from actin, so that the muscle can relax.

bones - calcium carbonate (limestone)blood - heme (iron)muscles - I can't think of one
43 "muscles" are used to frown...I'm not aware of bones used to frown
because without bones we would be a big fat blob. No movement will lead to no muscle growth, so we would be a big fat blob. That is if we had something to feed us, because without bones we would be a big fat unmovable blob unless we rolled around to get to places. Similar to a worm, but bigger and fatter. to make things easier to understand, no bones+no movement=big fat hairy blob.

The two systems that help move the body are the muscular system and the skeletal system. The muscles and ligaments contract and relax to move the bones they are attached to. The term used for the combination of both these systems is the musculoskeletal system
