The first step is to make a saw cut mid-sagittally through the palate as
shown. Because the nasal septum is
usually deviated to one side, your bisected nasal
cavity should have the nasal septum on one half and the lateral wall of the
nasal cavity on the other half.
This dissection exposes the inferior,
middle and superior
conchae on the lateral wall of the nasal cavity. Use your thin flexible probe
to locate the openings (e.g., infundibulum) into the cavity. . In the
nasopharynx identify the palate, torus tubarius and associated salpingopharyngeus
muscle (fold).
Take a moment to identify other muscular folds (e.g., palatoglossus,
palatopharyngeus) which are part of the oropharynx. Compare your dissection with
what is shown on a model.
