Which phase of deglutition is under voluntary control?
A) pharyngeal phase
B) esophageal phase
C) buccal phase
D) laryngeal phase
E) gastric phase

Accepted Answer

The buccal phase, also known as the oral preparatory phase, is the phase of deglutition that is under voluntary control. This phase involves the movement of food or liquid towards the back of the mouth in preparation for swallowing. The other phases (pharyngeal, laryngeal, esophageal, and gastric) are involuntary and cannot be consciously controlled.
