Detailed explanation-1: -Cardiac muscle is (c) striated, branching, with gap junctions within intercalated discs. These gap junctions allow the cardiomyocytes to synchronize their activity and consequently, the heart beat.
Detailed explanation-2: -Cardiac muscle cells are located in the walls of the heart, appear striped (striated), and are under involuntary control.
Detailed explanation-3: -Both cardiac and smooth muscle are involuntary while skeletal muscle is voluntary.
