Answer 2

The muscle is cardiac muscle.

Cardiac muscle comprises of cells that have fibres that are branched, cylindrical and contain one nucleus per cell.

The muscles are involuntary in nature and continuously undergo rhythmic extension and contraction. This is done as heart pumps the blood without our intervention. Pacemaker cells are responsible for contraction and relaxation of muscles.

The cells join each other by intercalated discs, which is characteristic of cardiac cells.
