Answer 2

• Voluntary muscle (skeletal, striped, or striated muscle) Muscle that is under the control of the will and is generally attached to the skeleton.
• An individual muscle consists of bundles of long muscle fibres, each bounded by a sarcolemma and containing sarcoplasm, sarcoplasmic reticulum, and many nuclei.

• In summary, skeletal muscle contractions are either isometric, in which the muscle does not change its length, or isotonic, in which the muscle changes its length without increasing tension.
