Abstract
Human parotid and submandibular glands have been studied histo-chemically and ultrastructurally, with the aim to achieve a morphological basis for establishing the relative importance for salivary secretion of the parasympathetic and sympathetic nervous system. The two glands are innervated by parasympathetic and sympathetic nerves, which are, no doubt, both of functional importance. The secretion which remains after damage of the parasympathetic nerves, due to surgical trauma or pathological conditions, is in all probability mediated largely by sympathetic nervous activity.
