Question 24

Anterior view of open mouth (labeled)

Answer 24

Question 25

Tonsillectomy image labeled

Answer 25

Question 26

Stage 1 of swallowing

Answer 26

Voluntary: the bolus is compressed against the palate and pushed from the mouth into the oropharynx, mainly by movements of the muscles of the tongue and soft palate

Question 27

Stage 2 of swallowing

Answer 27

Involuntary & rapid; the soft palate is elevated, sealing off the nasopharynx from the oropharynx and laryngopharynx. The pharynx widens and shortens to receive the bolus of food as the suprahyoid muscles and longitudinal pharyngeal muscles contract, elevating the larynx.

Question 28

Stage 3 of swallowing

Answer 28

Involuntary; sequential contraction Of all three pharyngeal constrictor muscles forces the food bolus inferiorly into esophagus.

Question 29

innervation of the pharynx (labeled)
