The sarcolemma (plasma membrane) of an unstimulated muscle cell is polarized—that is, the inside of the sarcolemma is negatively charged with respect to t
5. Contraction is terminated. No tetanus in cardiac muscle cells because.. Because the refractory period of the cardiac muscle cell action potential is almost the same length as the muscle contraction, another contraction cannot be initiated until the heart muscle has relaxed (ie the heart cannot...
Cardiac Muscle Contraction For the heart to pump throughout the body,cardiac musclein the myocardium has to be excited and contract uniformly. This is facilitated by a cardiacaction potentialthat is due to a change in the voltage or membrane potential in the plasma membrane of cardiac myocytes....

Harada K, Potter JD. Familial hypertrophic cardiomyopathy mutations from different functional regions of troponin T result in different effects on the pH and Ca2+ sensitivity of cardiac muscle contraction. J Biol Chem. 2004;279:14488–95.
The meaning of CARDIAC MUSCLE is the principal involuntary-muscle tissue of the vertebrate heart made up of striated fibers joined at usually branched ends and functioning in synchronized rhythmic contraction.
Cardiac muscle cells branch freely. A junction between two adjoining cells is marked by a critical structure called anintercalated disc, which helps support the synchronized contraction of the muscle. The sarcolemmas from adjacent cells bind together at the intercalated discs. They consist of desmosome...
