5 Multiple choice questions

  1. muscle that tenses the soft palate during swallowing. It runs from the medial pterygoid plate, sphenoid spine and auditory tube
    to the soft palate. Its tendon loops around the pterygoid hamulus (of medial pterygoid plate). It is innervated by the Mandibular division of the
    Trigeminal Nerve (V3).
  2. muscle that elevates the soft palate during
    swallowing. It runs from the cartilage of the pharyngotympanic tube to the
    palatine aponeurosis. It is innervated by Vagus Nerve (CN X).
  3. located in the middle meatus; has openings for secretions from frontal sinus, maxillary sinus and anterior ethmoid air cells
  4. anastomotic arterial plexus; Kiesselbach area
