What is the role of the tongue during the voluntary phase of swallowing?
Understand the Problem
The question is asking about the specific function of the tongue in the process of swallowing, particularly focusing on the voluntary phase where the action is under conscious control. It is seeking to identify the correct option that describes what the tongue does during this phase.
Answer
The tongue forms the bolus and moves it backwards and upwards.
The tongue separates the food into a bolus and moves it backwards and upwards towards the back of the mouth during the voluntary phase of swallowing.
Answer for screen readers
The tongue separates the food into a bolus and moves it backwards and upwards towards the back of the mouth during the voluntary phase of swallowing.
More Information
Swallowing begins with a voluntary phase where the tongue plays an essential role by forming a bolus and guiding it towards the oropharynx, setting the stage for the involuntary phases to follow.
Tips
A common mistake is to confuse the voluntary phase with involuntary actions, but this phase is controlled consciously.
