In order to determine the shape of human muscle cells a scientist microscope?

In order to determine the shape of human muscle cells, a scientist would use a microscope to observe stained tissue samples under high magnification. This allows for detailed visualization of the cells' structure, including their elongated, multinucleated fibers. The use of techniques such as immunofluorescence or electron microscopy can further enhance the clarity of cellular features, aiding in the understanding of muscle cell morphology and function.
