, allowing us to move. They also help the body perform other functions so we can grow and remain strong, such as chewing food and then moving it through the digestive system.
What is the general relationship between where bones are located in relation to muscles in your body?
Muscles keep bones in place and also play a role in the movement of bones. To allow motion, different bones are connected by joints. Cartilage prevents the bone ends from rubbing directly onto each other.
Muscles contract to move the bone attached at
the joint.
How do bones and muscles work together for movement?
The muscles of the muscular system keep bones in place; they assist with
movement by contracting and pulling on the bones
. To allow motion, different bones are connected by joints which are connected to other bones and muscle fibers via connective tissues such as tendons and ligaments.
How do muscles move the bones?
Muscles provide the tug on the bones needed
to bend, straighten, and support joints
. Muscles can pull on bones, but they can’t push them back to their original position, so the muscles work in pairs of flexors and extensors. The extensor muscle relaxes and stretches as the flexor muscle contracts to bend the joint.
How does bone contribute to movement?
Movement. Bones also play an important role in the movement of your body,
transmitting the force of muscle contractions
. Your muscles attach to your bones via tendons. When your muscles contract, your bones act as a lever while your joints form a pivot point.

What is the strongest muscle in the human body?
The strongest muscle based on its weight is
the masseter
. With all muscles of the jaw working together it can close the teeth with a force as great as 55 pounds (25 kilograms) on the incisors or 200 pounds (90.7 kilograms) on the molars.
Why do muscles always work in pairs?
