   • Definition and functions
   • Interior of pharynx (pharyngeal cavity)
     • Nasopharynx:
       • opening of auditory tube
       • torus tubarius
       • pharyngeal tonsil (adenoids)
       • pharyngeal recesses
       • salpingopharyngeal fold (salpingopharyngeus muscle)
     • Oropharynx:
       • palatine tonsil in palatine fossa
       • lingual tonsil
       • anatomy of palatine fossa, CN-IX
     • Laryngopharynx:
       • laryngeal inlet
       • piriform recesses
   • Musculature of pharynx:
     • Constrictors: superior, middle, inferior
     • Verticals:
       • stylopharyngeus
       • palatopharyngeus
       • salpingopharyngeus
   • Nerve and arterial supply
