Why can you bend your arms?

When you bend your arm your brain send signals to your arm muscles telling the biceps, your upper arm muscles, to contract, go taut or stretch, while telling your triceps, lower arm muscles, to relax, become less tense or ease. Both of these muscles act as an antagonistic pair and work together to bend the arm. Each muscle uses the bones in your arm, the Humerus, the ulna and the radius, as an anchor.MonkeyLover-Dinda

How do arm muscles and ligaments work together to support and facilitate movement in the upper body?

Arm muscles and ligaments work together to support and facilitate movement in the upper body by connecting bones and providing stability. Muscles contract to move the bones, while ligaments hold the bones together and help prevent excessive movement. This coordinated effort allows for smooth and controlled movement in the arms and upper body.
