Question

Consider the following four statements and select the incorrect option, stating the ones that are true (T) and the ones that are false (F) :

I. Upper and Lower Esophageal Sphincters work with opposite peristaltic movements.

II. Entry of food into the stomach from the esophagus is mediated by receptive relaxation..

III. Myenteric plexus and Meissner's plexus help in lubrication of the esophagus.

IV. Failure in regulation of flow by Upper Esophageal Sphincter leads to GERD.

• A. I.T II. T III.T IV.T
• B. I. F II. T III. F IV.T
• C. I.T II. F III.T IV. F
• D. I.T II. T III.T IV. F

Answer 1

The correct option is D

I.T II. T III.T IV. F

Statement IV is false because, GERD is caused due to prolapsed reflexes of the Lower Esophageal Sphincter (NOT the UES) epithelium leading to failure in the mechanism of Lower Esophageal Sphincter which pushes gastric acid juices into the esophagus causing GERD or Gastroesophageal reflux disease.
