WebSkeletal muscles (commonly referred to as muscles) are organs of the vertebrate muscular system and typically are attached by tendons to bones of a skeleton. The muscle cells of skeletal muscles are much longer than in the other types of muscle tissue, and are often known as muscle fibers. The muscle tissue of a skeletal muscle is … Nuclei present in skeletal muscle are about 50% myocyte nuclei and 50% mononuclear cell nuclei. Mononuclear cells found in skeletal muscle tissue samples from mice and humans can be indentified by messenger RNA transcription of cell type markers. Cameron et al. identified nine cell types. The majority (83%) of mononuclear cells in skeletal muscle are located within or adjacent to blood vessels. They include endothelial cells (45% of cells), fibro-adipogenic progenitors (FAPs)(…
