Influence of autonomic nerves and drugs on myoepithelial cells in parotid glands of cat.
When a single electrical shock is applied to either the parasympathetic or to the sympathetic nerves a pressure rise is seen in the parotid duct of the cat, probably due to myoepithelial cell activation. No secretion occurred on single impulse stimulation. When repetitive stimulation was used both divisions of the autonomic nervous system could evoke secretion. The motor response to sympathetic stimulation was mediated via alpha-receptors while secretion mainly was mediated via beta-receptors.
