Explanation:

Cardiac muscles are the muscles that are found in the heart. The structure of the cardiac muscle is such that it provides the heart enough power and elasticity to pump blood efficiently. The cardiac muscles are involuntary muscles that have striations and a single nucleus. Further, they have a branched structure and have intercalated discs which help the heart to beat in a synchronized function. Please see the attached image for the structure of the cardiac muscle.
