When they contract
Muscles cause bones to move when they contract. This contraction exerts force on the tendons, which in turn pull on the bones, resulting in movement at the joints. The interaction between muscles, tendons, and bones allows for various movements and activities.
Muscles contract and relax to pull/push
sarcomere's are the functional unit of a muscle which contract and make muscles shorter which then cause bones to move.

Muscles and tendons move bones at the joints. You can not actually "move bones" on your own, rather you can only contract and relax certain muscles and tendons specifically told to listen to you.
Muscles. They contract and relax to allow movement of our bones.
The way the muscles are attached to the bones is what facilitates locomotion. The muscles contract which makes the bones move and creates locomotion.
Muscles attached to bones contract and generate force, pulling on the bones they are attached to. This force causes the bones to move, resulting in movement of the body. The attachment of muscles to bones via tendons allows for efficient transfer of force and movement.
Muscles contract and relax to move bones at joints. This coordinated action allows for smooth and precise movements. The muscles provide the force needed to move the bones, and the bones provide a framework for muscles to exert their force.
Bones act as levers in the body by providing a rigid support for muscles to attach to. When muscles contract, they pull on the bones, creating movement around joints. The length and position of bones determine the leverage and force that muscles can exert to move the body.
Muscles contract to generate force, while tendons connect muscles to bones to transmit that force. Ligaments connect bones to each other at joints, providing stability and limiting excessive movement. Joints allow bones to move together, with the coordination of muscles, tendons, and ligaments, to produce various types of movement.
