Solution
The correct order of the events of deglutition, beginning with the voluntary phase of swallowing, is as follows:
- The tongue elevates the bolus toward the oropharynx.
- The soft palate closes off the nasopharynx.
- Successive contraction of the superior and middle pharyngeal constrictors moves bolus through pharynx.
- Contraction of the inferior pharyngeal constrictor relaxes the upper esophageal sphincter and allows the bolus to enter the esophagus.
- The lower esophageal sphincter relaxes.
- Peristaltic contractions of the esophagus move the bolus through the esophagus.
