Detailed explanation-1: -Muscles that are under the control of the will of an individual are striated muscles. The muscles in your arms move only when you want; for example, when you want to lift a box from the ground. Such muscles constitute about 50 percentage of the body weight.

Detailed explanation-2: -The body possesses two types of striated muscle, cardiac and skeletal.

Detailed explanation-3: -They have alternate light or dark bands known as striations. The striated muscles are located in the muscles of the face, neck, limbs, etc. They are also found in the pharynx, tongue, diaphragm, and upper part of the esophagus.

Detailed explanation-4: -Skeletal muscles are under our conscious control, which is why they are also known as voluntary muscles.

Detailed explanation-5: -Titin anchors the A band in the middle of the sarcomere and may determine thick-filament length and thus A-band length. In the 1970s it was proposed that the intermediate filament desmin, which surrounds the Z disks, connects adjacent myofibrils, resulting in the striated appearance of a skeletal muscle fiber.
