Which type of muscle is characterized as voluntary and striped?

Skeletal muscle is characterized as voluntary and has a striated appearance due to the organized arrangement of actin and myosin filaments within the muscle fibers. This unique structure allows for precise control of movement, enabling individuals to move their muscles consciously and intentionally. Skeletal muscles are typically attached to bones and are responsible for voluntary movements such as walking, lifting, and speaking.

The "voluntary" aspect means that the contraction of skeletal muscles is under conscious control, unlike other types of muscle, such as cardiac or smooth muscles, which operate automatically. The striations, or stripes, observed in skeletal muscle fibers are a distinct feature that distinguishes them from non-striated (smooth) muscle, which lacks this striped appearance.

This understanding of skeletal muscle is crucial in the field of nail technology, as the use of hand muscles significantly impacts the precision and dexterity required for manicures, pedicures, and other nail enhancement procedures.
