Verified step by step guidance

Understand the structure of skeletal muscle fibers: Skeletal muscle fibers are long, cylindrical cells that are multinucleated. This is a key characteristic that differentiates them from other muscle types.

Compare skeletal muscle fibers to cardiac muscle cells: Cardiac muscle cells are branched and contain intercalated discs, which are specialized junctions for communication and contraction. Skeletal muscle fibers do not have these features.

Examine the presence of striations: Skeletal muscle fibers are striated, meaning they have a striped appearance due to the arrangement of actin and myosin filaments. This is another distinguishing feature.

Clarify the multinucleated nature of skeletal muscle fibers: Each skeletal muscle fiber is formed by the fusion of multiple myoblasts during development, resulting in a single cell with multiple nuclei.

Conclude by identifying the correct statement: Based on the characteristics discussed, the correct answer is that each skeletal muscle fiber is a single, multinucleated cell.
