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.

There are major differences in the metabolism of morphine and the illegal drug heroin. Morphine mostly produces its CNS effects through m-receptors, and at k- and d-receptors. Heroin has a slight affinity for opiate receptors. Most of its actions are due to metabolism to active metabolites (6-acetylmorphine, morphine, and morphine-6-glucuronide).
