What are the functions and interactions of the muscles and tendons in the arm?

The muscles and tendons in the arm work together to allow movement and stability. Muscles contract to produce movement, while tendons connect muscles to bones, transmitting the force generated by the muscles to move the bones. This coordinated action enables the arm to perform various tasks, such as lifting, pushing, and pulling. Additionally, the muscles and tendons in the arm also help maintain posture and provide support for the joints.
