Give three features of cardiac muscles.

Three features of cardiac muscles are: 

(i) Cardiac muscles are involuntary muscles that contract rapidly, but do not get fatigued. 

(ii) The cells of cardiac muscles are cylindrical, branched, and uninucleate. 

(iii) They control the contraction and relaxation of the heart.

(ii) The cells of cardiac muscles are cylindrical, branched, and uninucleate.

(iii) They control the contraction and relaxation of the heart.

1. Cardiac muscles are cylindrical, branched and uninucleate,

2. These work continuously (from birth to death),

3. These do not get fatigue.

(i) Cardiac muscles are involuntary.
(ii) Cardiac muscle cells are cylindrical, branched and uninucleate.
(iii) Cardiac muscles show rhythmic contraction and relaxation throughout the life.

2. The cells of cardiac mucles are cylindrical , branched and uninucleate.
3. Cardiac muslce show rhytmic contraction and relaxation throughout the life.
