APPLIED RADIOLOGICAL ANATOMY

Detailed explanation-1: -Three types of chemoreceptors found in the small intestine are likely responsible for feedback control of gastric emptying by nutrients; they are osmoreceptors, lipid receptors, and receptors for amino acids.

Detailed explanation-2: -At least five different sensory receptors have been identified in the mucosa, which respond to mechanical, thermal, osmotic and chemical stimuli.

Detailed explanation-3: -Parasympathetic signalling via muscarinic acetylcholine receptors (mAChRs) regulates gastrointestinal smooth muscle function. In most instances, the mAChR population in smooth muscle consists mainly of M2 and M3 subtypes in a roughly 80% to 20% mixture.

Detailed explanation-4: -Inositol Phosphates. Receptors, Cell Surface. Adenylyl Cyclases.
