WebThe conduction system consists of specialized heart muscle cells, situated within the myocardium. [3] There is a skeleton of fibrous tissue that surrounds the conduction system which can be seen on an ECG. Dysfunction of the conduction system can cause irregular heart rhythms including rhythms that are too fast or too slow . Structure [ edit] WebA Muscle Contraction Is Triggered When an Action Potential Travels Along the Nerves to the Muscles Muscle contraction begins when the nervous system generates a signal. The signal, an impulse called an action potential, travels through a type of nerve cell called a …

WebExpert Answer. Answer is Option A is correct;Sarcolemma.In order for the excitation-contraction coupling to occur, the production of an action potential must occur within the … WebThe Action Potential. Resting membrane potential describes the steady state of the cell, which is a dynamic process that is balanced by ion leakage and ion pumping. Without any outside influence, it will not change. To get an electrical signal started, the membrane potential has to change.
