All-or-none Response: Phenomenon in which a muscle fiber contracts completely when exposed to a threshold stimulus, or not at all. When a skeletal muscle is stimulated to contract by a motor neuron a minimum amount of stimulus is needed to start the process of muscle contraction.
â¢ Skeletal muscles are called voluntary because their contractions can be consciously controlled. â¢ The connective tissues contain the nerves and blood vessels that supply the muscle fibers. â¢ Nerves penetrate the epimysium and branch through the perimysium and enter the endomysium to innervate individual muscle fibers. Contain more muscle fibers than a parallel muscle and as a result, generate more tension than that of a parallel muscle of the same size. â¢ One or more tendons runs through the body of the muscle. â¢ Fascicles form an oblique angle to the tendon.
