These plexi provide innervation via adrenergic fibers to the enteric plexi, and directly to vascular smooth muscle. Actions of sympathetic stimulation. General inhibition of motor and secretory function. B. Parasympathetic Innervation. 7th and 9th cranial nerves innervate salivary glands.
Vagal branches innervate esophagus to descending colon including liver, pancreas and gall bladder.
Descending colon to anus innervated by pelvic nerves. Actions of parasympathetic stimulation. General increase in motor and secretory function. Elicit reflex responses between enteric and preganglionic plexi. Provides information to hypothalamus regulating moment to moment feeding behavior.
