Skeletal muscle appears to be striped or “striated”. It looks like a rugby shirt with horizontal stripes of light and dark striations. There are parallel bundles of fibers in the muscle.
Like skeletal muscle, cardiac muscle appears striated or striped. The bundles are arranged in a tree-like fashion, but they are joined at the ends by twine. As opposed to skeletal muscle tissue, cardiac muscle contractions are involuntary since they are not under conscious control.
Smooth muscle cells are smaller than those in skeletal muscle. Striations are absent from their spindle-like appearance. Instead, they are made up of a variety of filaments, both thin and thick.
