Abstract:
Intrinsic enteric neurons regulate gut motility, secretion, and absorption, whereas extrinsic dorsal root ganglia sensory neurons are key in colon interoception and visceral pain. A new study raises the question of whether some initial interoceptive signals could originate from enteric neurons.

Drug Delivery: Enteral Route
Routes of Drug Administration: Enteral
Enteral administration involves drug administration via the mouth in two ways: orally or sublingually.
Unlike sublingually drugs, drugs that are taken orally pass through the gastrointestinal (GI) tract and get metabolized by the liver. Once metabolized, the drug is absorbed into the systemic circulation, reaching different body parts via the bloodstream. However, while passing through the stomach,...
