SpletOne major difference is in the duration of the action potentials. In a typical nerve, the action potential duration is about 1 ms. In skeletal muscle cells, the action potential duration is approximately 2-5 ms. In contrast, the duration of cardiac action potentials ranges from 200 to … SpletThe term used to describe fluid collecting in the pericardial cavity that restricts the movement of the heart is known as A) cardiac tamponade.

Splet27. sep. 2024 · The prolonged plateau phase of the cardiac action potential means that the ARP is 200 ms, which is considerably longer than that of the nerve action potential. The long ARP of cardiac muscle means that further action potentials cannot be triggered until muscle contraction is nearly complete (Figure 57.3b). A short ARP could potentially lead … sterling isa contact number
