| Tensor Veli Palatini OINA | O- Medial pterygoid plate, cartilage of pharyngotympanic tube I- palatine aponeurosis N- Mandibular A- tenses soft palate and opens mouthof pharyngotympanic tube during swallowing and yawning |
| Levator Veli Palatini OINA | O- cartilage of pharyngotympanic tube I- palatine aponeurosis N- Vagus nerve via pharyngeal plexus A- Elevates soft palate during swallowing and yawning |
| Palatoglossus OINA | O- palatine aponeurosis I- side of tongue N- vagus nerve via pharyngeal plexus A- elevates posterior part of tongue |
| Palatopharyngeus OINA | O- hard palate and palatine aponeurosis I- lateral wall of pharynx N- vagus nerve via pharyngeal plexus A- tenses soft palate and pulls walls of pharynx superiorly, anteriorly, and medially during swallowing |
| Musculus uvulae OINA | O- palatine aponeurosis I- mucosa of uvula N- vagus nerve via pharyngeal plexus A- shortens uvula and pulls it superiorly |
| What division of the pharynx is superior of uvula? | Nasopharynx |
