Muscles. Muscles are attached to bones by tendons and help them to move. When a muscle contracts (bunches up), it gets shorter and so pulls on the bone it is attached to. ... One muscle will contract and pull a joint one way and another muscle will contract and pull it the other.

Muscles allow us to consciously move our limbs, jump in the air, and chew our food.
But they are also responsible for many more processes that we cannot actively control, such as keeping our hearts pumping, moving food through our guts, and even making us blush.
Our muscles need signals from our brains and energy from our food to contract and move.
To build new muscles through exercise, we make use of their remarkable ability to repair themselves when damaged.
