What is Which of the following is true regarding the action potential of skeletal muscle? and explain in detail?
Depolarization of the muscle fibers is essential for initiating muscle contraction. The action potential of skeletal muscle is transmitted to all of the fibrils along T-tubules, triggering the release of Ca2+ from the lateral sacs of the sarcoplasmic reticulum next to the T-system. The electrical events in skeletal muscle and the ionic fluxes underlying them are similar to those in nerve. In contrast, the action potential in cardiac muscle is longer and has a prolonged plateau phase.
