The coordinated actions of muscles, tendons, and ligaments at the elbow joint facilitate flexion and extension of the forearm. This physiological process allows for a diverse range of movements, enabling activities from lifting objects to performing fine motor tasks. The musculoskeletal structures work synergistically to achieve smooth and controlled articulation.
The ability to move the forearm relative to the upper arm is fundamental to human function. This action underpins a significant portion of daily activities, impacting efficiency and precision in both work and leisure. Historically, this capability has been integral to tool use, construction, and the development of advanced technologies, influencing human societal progress.
