The description given in the question matches the characteristics of cardiac muscle fibers. Cardiac muscles are striated, meaning they have alternating light and dark bands visible under a microscope. They also form Y-shaped branches and have junctions called intercalated discs, which allow for rapid communication between adjacent cells. Smooth muscle fibers do not have striations or intercalated discs, while skeletal muscle fibers do not form Y-shaped branches or have intercalated discs.
