What if a bone had only one muscle attached to it?
muscles can only pull so a bone with only one muscle on it would be pulled to the extreme of the muscles contraction and stay there.
What movement of the skeletal muscle will make the bones move?
Muscles move bones only by contraction. The human finger for example... on one side of the finger is a set of muscles that extends the finger away from the palm and on the other side are a set of muscles that pull the the finger to the palm. Both work by a series of shortenings of the fibers inside the muscles.
Why must skeletal muscles work in pairs to move a bone?
Skeletal muscles work in pairs to move a bone so that the muscles can function properly. Muscles can only pull, therefore bones need two muscles to make it move. To put a finger up one muscle might pull, the other will put to put back down. With two, the movement will be smooth, otherwise it will be "jerky" and uncontrolled.
Do some muscle cells pull when they contract and others push as relax?
No muscle cells push, it just depends which muscle is doing the pulling. In a common joint, one muscle is used to pull the body part one way, and a different one is used to pull it back.
What will the other muscle do while the thumb is pulled toward the finger?
When one muscle contracts, the other one expands.
Do muscle push bones to make them move?
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.
