title: Perivascular nerves in the rat submandibular salivary gland.
abstract: Perivascular nerves in the rat submandibular salivary gland have been studied using a variety of histochemical procedures coupled with electron microscopy. Two principal nerve types, adrenergic and cholinergic, appear to predominate and are localized principally around arterioles. Venules are rarely innervated. The possibility that a non-adrenergic non-cholinergic nerve population might influence blood flow is discussed critically in the light of anatomical and physiological findings.
