| Abstract;Subjects were used to swallow a capsule containing barium, and the sensation of the capsule being caught in the throat was examined. Twenty normal persons (18 males, 2 females) with a mean age of 38 years (31-51) were used as subjects. Subjects were asked to swallow a No.0 capsule containing barium powder, and the place where the capsule stopped in the esophagus was compared with the place where the subject felt it. Many subjects felt the capsule had stopped proximally when the capsule stopped between the cricopharyngeal constriction and the bronchial constriction of the esophagus. They felt it had stopped at the level of the 7th cervical. When the capsule was stopped at the level of the aortic arch in the bronchial constriction, some subjects felt it had stopped at the level of the 7th cervical vertebra. When it had stopped below the center of the aortic arch, none of the subjects had the sensation of it being caught in the throat. Thus, of the subjects in whom the capsule stopped between the cricopharyngeal constriction and the bronchial constriction, or in the bronchial constriction, those who felt it was caught in the region of the 7th cervical vertebra reported a feeling of it being caught in the throat.
