Cardiac muscle tissue, like skeletal muscle tissue, looks striated or striped. The bundles are branched, like a tree, but connected at both ends. Unlike skeletal muscle tissue, the contraction of cardiac muscle tissue is usually not under conscious control, so it is called involuntary.
Skeletal muscle looks striped or “striated” – the fibres contain alternating light and dark bands (striations) like horizontal stripes on a rugby shirt. In skeletal muscle, the fibres are packed into regular parallel bundles.
Compared to skeletal muscle, smooth muscle cells are small. They are spindle shaped and have no striations. Instead, they have bundles of thin and thick filaments.
