Extension: Extension is an anatomical term used to describe a general action of a muscle on a bone or joint. When a muscle extends, it straightens or increases the angle of two body parts, such as when the knees are extended in the act of standing up. In the hip and shoulder joints, extension means moving the related arm or leg toward the posterior or back area of the body.
Extension is the opposite action of flexion. Conditions that can affect normal extension include musculoskeletal trauma, bone fracture, myalga, muscle/tendon rupture, muscle/tendon tears, strains, arthritis, myopathy, atrophy, infectious myositis, and neuromuscular diseases.
