Involuntary muscles would be things like your heart and the muscles around your intestines, which you generally cannot consciously control. The skeletal is called voluntary muscle because it is usually subject to conscious control.
Generally, these muscles are attached to bones of the skeleton, thus called the skeletal muscles. Skeletal muscles are striated and are made up of multinucleate cells. Each cell is referred to as muscle fiber.The cell membrane of muscle fiber is known as sarcolemma, and the cytoplasm is called sarcoplasm. Unlike involuntary muscles, voluntary muscles are attached to bones. Involuntary muscles are visceral. â¢ Voluntary muscle tissue is made up of cylindrical fibres, while involuntary muscles (smooth muscles) are made up of spindle-shaped fibres.
