Question

Give two features of cardiac muscles​

Answer 1

Answer:

Cardiac muscle is striated muscle that is present only in the heart. Cardiac muscle fibers have a single nucleus, are branched, and joined to one another by intercalated discs that contain gap junctions for depolarization between cells and desmosomes to hold the fibers together when the heart contracts

Answer 2

Explanation:

Cardiac muscles are involuntary muscles. They are involved in continuous rhythmic contraction and relaxation.

Cardiomyocytes or the cardiac cells are uninucleate, cylindrical, and elongated.

Cardiac muscles display faint cross-striations which do not get fatigued under normal circumstances.
