Final answer:
True, the salpingopharyngeus and palatopharyngeus muscles are responsible for elevating the pharynx and larynx during the swallowing process.
Step-by-step explanation:
The statement that the salpingopharyngeus and palatopharyngeus elevate the pharynx and larynx is true. During swallowing, these muscles, along with others, work to raise and expand the pharynx to receive the bolus of food. As part of this coordinated movement, the larynx is also pulled superiorly. This action is critical as it allows the epiglottis to swing downward and close the opening to the trachea, preventing food and beverages from entering the trachea and potentially causing choking or aspiration. The salpingopharyngeus and palatopharyngeus are two of the elevator skeletal muscles of the pharynx that contract during swallowing, contributing to these important processes.
