[Intrinsic autonomic innervation of the stomach during aging].
In the senescence the cholinergic network of the basal and interglandular lamina propria and of the muscularis mucosae and submucosa of the gastric wall undergoes small modifications, while the adrenergic innervation decreases severely in the muscularis mucosae and in the interglandular tissue. Having regard to this adrenergic failure we note histochemically a rupture of the cholinergic/adrenergic balance in favour of the cholinergic innervation. These modifications disturb the gastrointestinal motility but their influence on the secretory reflex has to be demonstrated.
