Question 49

Swallowing has __ steps

Answer 49

5

Question 50

step 1

Answer 50

the tongue and buccinator muscles move the food bolus towards the back of the mouth towards the pharynx.

Question 51

step 2

Answer 51

the suprahyoid muscles pull the hyoid superiorly and anteriorly towards the mandible, which then widens the pharynx and moves the larynx under the epiglottis (remember, the larynx is anterior to the pharynx). The other 3 suprahyoid muscles that aid in “lifting” the hyoid bone are: stylohyoid, geniohyoid, and mylohyoid muscles

Question 52

step 3

Answer 52

small muscles elevate the soft palate and close off nasal passages—these muscles are called tensor veli palatini and levator veli palatini. The palatini muscles that aid in elevation of the soft palate are located superiorly to the soft palate.

Question 53

step 4

Answer 53

the food gets propelled inferiorly in the esophagus by pharyngeal constrictor muscles of the pharynx. The pharyngeal constrictor muscles include: the superior, middle, and inferior pharyngeal constrictor muscles. These muscles wrap themselves around the pharynx.

Question 54

step 5

Answer 54

infrahyoid muscles “reset” the positions of the hyoid and larynx by pulling the hyoid posteriorly and inferiorly back into position, thus ending the act of swallowing

Question 55

a dysfunction in the inability to swallow appropriately

Answer 55

oropharyngeal dysphagia
