What best describes skeletal muscles?

Skeletal muscles are the ones attached to bones by tendons, and they contract to move the skeleton. This movement happens when they shorten, pulling on the bones and creating joint motion. These muscles are under conscious control (voluntary) and typically have a striped appearance under a microscope. The other descriptions refer to different muscle types. Smooth muscles line internal organs and vessels and work involuntarily, such as in digestion. The heart’s muscle is cardiac and powers heartbeat, also involuntary. So the description that matches skeletal muscles best is the one about being connected to bones via tendons and driving skeletal movement.
