Which is TRUE about gastric motility?

Question

Quizplus · Accepted Answer

The basic electrical rhythm of the gastric smooth muscle remains constant at three depolarizations per minute even in the absence of food.

Answer: B
 Gastric contractions are stronger in the antrum (lower part) of the stomach, which helps to churn and mix the food with gastric juices.

Answer: C
 Gastrin increases the force of contraction while enterogastrones decrease it.

Answer: D
 When the wave of excitation reaches the pyloric sphincter, the action potentials become inhibitory, and the sphincter narrows to regulate the exit of chyme into the duodenum.

Answer: E
 The term “slow waves” refers to the electrical activity of smooth muscles in the stomach, while “pacemaker” refers to interstitial cells of Cajal that generate electrical activity for slow waves.
