Noradrenergic innervation of the gastric mucosa. Immunoreactivities for dopamine β-hydroxylase (DBH (a, c)) and tyrosine hydroxylase (TH (b)) were used to locate noradrenergic axons. The most prominent innervation was of arterioles (a) and small arteries (art). The internal elastic lamina of the artery is autofluorescent (asterisk (c)). There were very few axons in the mucosa. Immunoglobulins in the anti-TH antiserum bound to immune cells (asterisk, b). Axons were in the muscularis mucosae (mm) and circular muscle (cm). Images from corpus
