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.

This condition is progressive and worsens with time. More than 100 million people in the United States are nearsighted, but only 20% of those are born with the condition.
