Anatomy of Articulation and Resonance
Articulation and Resonance Class Activity 1
Lecture Discussion Questions
1. What is the function of the articulatory system?
2. What are the moveable articulators?
3. What are the immoveable articulators?
4. What is the source-filter theory of vowel production?
5. What components make up the nasal septum?
6. What bone is continuous with the nasal septum and the braincase?
7. What structures serve to heat and humidify the air as it enters the body through the nose?
8. What bones contribute to the hard palate?
9. What are the components of the hard palate?
10. What is the major muscle of the velum?
11. Trick question: What does the tensor veli palatini do?
12. Where is the orifice of the Eustachian tube, anatomically?
13. What muscle underlies the anterior faucial pillars?
14. What muscle underlies the posterior faucial pillars?
15. Is the glossopalatine a muscle of the soft palate or of the tongue?
16. The genioglossus has muscle spindles. If they are triggered to respond, what will happen to

17. The palatoglossus (glossopalatine) has muscle spindles. If they are triggered to respond, what
will happen to the tongue and soft palate?
18. Don’t you think it’s curious that the dentist will inject deep in your mouth (at the posterior
aspect of the mandible) to deaden your mandibular incisors? Why would she do that?

Effects of Pathologies on Articulatory System
1. Cleft palate: A discussion on the nature of cleft palate, including the relationship between
movement of the palatine processes during early development and the potential for problems
2. Orofacial myofunctional disorders: You might use our Figures 6-23 and 6-29 for this as
illustration. The notion is that one problem can give birth to a host of other problems through
3. Cleft lip: You might want to use our Figure 6-12 to support this discussion. Cleft lip appears
to be a failure of tissue to join during the fourth through seventh weeks of gestation. As the
4. Micrognathia, retrognathia, and protruded mandible: Our Figure 6-29 will be useful here.
Sometimes the dance of development is thrown off by structural hypoplasia for various

1. If you have access to cleft palate speakers—an old series of cineradiographic studies—it is
2. There is a nice series of Moving Picture Experts Group (MPEG) videos from the Smile
