Skeletal muscle cells are characterized by their striated appearance when visualized under the light and electron microscopes. Collectively, skeletal muscle cells make up approximately 50% of the body’s wet (i.e., soft tissue) weight. Skeletal muscle cells perform highly important functions including generating force, motion, and even heat. Test your basic knowledge of skeletal muscle physiology by taking this simple quiz.
