Detailed explanation-1: -Cardiac muscle cells are cylindrical and branched. They are involuntary in nature. They do not undergo the fatigue. They are present only in the human heart.
Detailed explanation-2: -Rapid, involuntary contraction and relaxation of the cardiac muscle are vital for pumping blood throughout the cardiovascular system. To accomplish this, the structure of cardiac muscle has distinct features that allow it to contract in a coordinated fashion and resist fatigue.
Detailed explanation-3: -This is primarily because the heart is made of cardiac muscle, consisting of special cells called cardiomyocytes. Unlike other muscle cells in the body, cardiomyocytes are highly resistant to fatigue.
Detailed explanation-4: -Cardiac muscle cells are located in the walls of the heart, appear striped (striated), and are under involuntary control.
Detailed explanation-5: -Class 11. »Biology. »Locomotion and Movement. »Muscles. »Cardiac muscles are resistant to fatigue.
