Answer 1

Answer:

Cardiac muscles are present in the heart. Cardiac muscle tissue fibres are striated and involuntary muscle fibres. The myofibrils have dark and light bands, thus they are striated but they are not under the control of the will of the animal, thus they are involuntary. They have intercalated discs at intervals. These discs permit the wave of muscle contractions to be transmitted from one cardiac fibre to another. This provides quick powerful and rhythmic contractions to the heart.

So the correct answer is 'Both statements 1 and 2 are correct'.
