Which Best Describes a Muscle Fiber

Skeletal muscle fibers tend to be shorter than smooth muscle fibers. Slow twitch muscle fibers are known as type I fibers and the name describes the fact that they contract slowly and steadily.

The thick filament needs ATP to bind to the thin filament. Now up your study game with Learn mode. Or B the sarcomere extends as the actin filaments pull the myosin away from the M line.

Skeletal muscle cells have one nucleus but smooth muscle cells are multinucleated. They possess desmosomes to attach cardiac muscle fibers to one another gap junctions that allow ions to pass between cells to allow action potentials to be conducted between cells and tight junctions that prevent calcium from passing between cells. A motor unit is defined as - A single nerve fiber and the muscle it innervates.
