Difference between cardiac action potential and skeletal action potential |
|
Answer» In skeletal muscle CELLS, the action potential duration is approximately 2-5 ms. In contrast, the duration of cardiac action potentials range from 200 to 400 ms. Another difference between cardiac and nerve and muscle action potentials is the role of calcium IONS in depolarization. An action potential OCCURS when a neuron sends information down an axon, away from the cell body. Neuroscientists use other words, such as a "spike" or an "impulse" for the action potential. ... Action potentials are caused when different ions cross the neuron membrane. A STIMULUS first causes sodium channels to open. thnx ..hope dis hlps uh |
