What generally makes skeletal muscles differ from smooth and cardiac muscles?

Skeletal muscles are primarily under voluntary control, allowing for conscious movement, while smooth and cardiac muscles are involuntary, functioning automatically. Skeletal muscles are striated due to their organized fiber structure, whereas smooth muscles are non-striated, and cardiac muscles have a unique striated structure with intercalated discs that facilitate synchronized contractions. Additionally, skeletal muscles are typically attached to bones, enabling movement of the skeleton, while smooth muscles are found in the walls of hollow organs and blood vessels, and cardiac muscles are exclusive to the heart.
