Schematic presentation of the distribution of serotoneric and dopaminergic fibers over the salivary gland complex The salivary gland is innervated by the salivary nerve (1) and via branches of the esophageal nerve (2). The salivary nerve accompanies the reservoir duct and contains one thick dopaminergic axon. Moreover, several serotonergic fibers ramify within the nerve and have numerous varicosities. Nerves containing numerous dopaminergic varicose fibers (3) link the acinar lobules and may function as neurohemal organs.
