Document Summary
Biomechanics: focuses on the mechanisms through which the musculoskeletal components interact to create movement. Fleshy attachments: most often found at the proximal end of a muscle, muscle fibers are directly. Insertion: distal attachment, more mobile suffixed to the bone usually over a wide area so that force is distributed rather than localized. Fibrous attachments: such as tendons, blend into and are continuous with both the muscle sheaths and the connective tissue surrounding the bone. The muscle most directly involved in bringing about a movement is called the prime mover, or agonist. The muscle that can slow down or stop the movement is called the antagonist. Assist in joint stabilization and in braking the limb toward the end of a fast movement protects ligamentous and cartilaginous joint structures from potentially destructive forces. A muscle is called a synergist when it assists indirectly in a movement.
