Select the correct statement about the function of myocardial cells.
◦ The refractory period in skeletal muscle is much longer than that in cardiac muscle.
◦ The influx of potassium ions from extracellular sources is the initiating event in cardiac muscle contraction.
◦ The entire heart contracts as a unit or it does not contract at all.
◦ Cardiac muscle cells are innervated by sympathetic, parasympathetic, and somatic nerve fibers so that the nervous system can increase heart rate.
