Question

Quizplus · Accepted Answer

Manometry is a test that measures the motor function of the esophagus. It involves placing a tube with sensors through the nose and into the esophagus to measure the strength and coordination of the muscles that control swallowing. Fluoroscopy, endoscopy and a barium swallow can provide information about the structure of the esophagus, but do not directly measure its motor function.
