Major structures to pass through the pharyngeal wall superior to the superior constrictor muscle?

Major structures to pass through the pharyngeal wall superior to the superior constrictor muscle?

• A. Auditory tube, Levator veli palatini
• B. Auditory tube, Tensor veli palatini
• C. Palatine tonsil, Stylopharyngeus
• D. Internal carotid artery, Internal jugular vein

Answer: (A)

The region just above the superior constrictor forms the boundary of the nasopharynx where the auditory (pharyngotympanic) tube opens into the nasopharyngeal wall, and the levator veli palatini shapes that opening. The auditory tube runs from the middle ear to this area, and the levator veli palatini forms much of the wall around the tube and elevates the soft palate during swallowing. These are the major structures that pass through the pharyngeal wall above the superior constrictor. The tensor veli palatini is involved with opening the auditory tube but it does not itself pass through the wall in this location; it loops around the pterygoid hamulus to reach the palatal aponeurosis. The other options involve structures that lie elsewhere (palatine tonsil, stylopharyngeus) or vascular structures (internal carotid artery, internal jugular vein) that do not pass through this pharyngeal wall region.
