Final answer:
The Oral preparatory phase is when patients may experience pocketing of food in the cheeks due to dysfunction in muscle control when preparing the bolus for swallowing. So, the correct answer is option A) Oral preparatory phase.
Step-by-step explanation:
Patients may experience pocketing of food in the cheeks during the Oral preparatory phase of swallowing. This phase involves the control over when to swallow the food after chewing has been completed.
The tongue aids in moving the food into position for swallowing, but if there is dysfunction in the muscle control of the cheeks or tongue, food may become lodged in the cheek pockets instead of being pushed to the back of the oral cavity and into the oropharynx.
According to the options provided, the correct answer is A) Oral preparatory phase.
