Page 4: Parasympathetic and sympathetic nerves innervate the GI tract. â¢ Both parasympathetic and sympathetic divisions of the autonomic nervous. system control digestion by contacting the enteric nervous system in the. wall of the digestive tract. â¢ The parasympathetic division typically stimulates digestion while the. sympathetic division typically inhibits it.
A second control element is sympathetic nervous discharge to the kidney, which stimulates renin secretion through Î²-adrenergic receptors on the JGCs (). Increased renin secretion in response to Î²-adreneroceptor stimulation is mediated via the formation of cAMP. second control element is sympathetic nervous discharge to the kidney, which stimulates renin secretion through Î²-adrenergic receptors on the JGCs ().
