Abstract

The fluorescence histochemical method has been used to investigate the adrenergic innervation of the vessels of the gastrointestinal tract. Both stretch preparations and sections of blood vessels taken from cats, guinea-pigs, rabbits and rats were examined. A dense innervation of the major mesenteric arteries and their branches was found. Most of the nerve fibres are at the adventitio-medial border, but a few fibres penetrate the mediae of some large arteries. The innervation of the arterial branches in the gut wall is also dense, particularly in the submucosa. Generally, adrenergic nerves do not accompany capillaries. Arterio-venous shunts are apparently without any specialised adrenergic i..
