Figure 1. Diagram of the integrated motor activity of the gastric fundus, antrum, pylorus, and
duodenum associated with rapid and slow gastric emptying. Rapid emptying is associated
with an increase in fundic tone, strong phasic contractions of the antrum, a wide open
pylorus, and coordinated duodenal contractions. Slow emptying is associated with fundic
relaxation, shallow phasic contractions of the antrum, an increase in phasic and tonic activity
of the pylorus, and uncoordinated or random duodenal contractions. longitudinal layer that …
