MECH 4 SPEECH EXAM QUESTIONS AND
CORRECT ANSWERS
Pharyngeal-oral anatomy and functions of speech production - CORRECT ANSWERS The
pharyngeal-oral apparatus consists of a "tube" that extends from the larynx to the lips. It bends
at the right angle at the junction between the pharyngeal and oral portions 'oropharynx'
Articulators - CORRECT ANSWERS Define: structures brought into contact to alter shape of
vocal tract for speech sounds. Provide additional sound sources of vibration energy at points in
the tract above the vocal folds.
Lists of articulators: soft palate, hard palate, pharynx, lips, mandible, tongue, and teeth.
How articulators work together? - CORRECT ANSWERS Sequencing and overlapping of
multiple gestures with timing of when one gesture begins relative to another being important!
There is also some pre-planning by the brain.
When articulators don't work together - CORRECT ANSWERS Example 1: mutation of gene
FOXP2, causing orofacial sequencing deficits
A single mutation in the DNA sequence for the gene FOXP2 leads to verbal dyspraxia evident
developmentally
Structural changes in the brain such as cortical and basal ganglia regions
Identify nasal bones - CORRECT ANSWERS List: frontal bone, nasal bone, cartilage,
ethmoid bone, vomer bone, maxillary bone, palatine bone

-What is their function
Bones of the face - CORRECT ANSWERS List: zygomatic, palatine, maxilla, mandible
What is their function?
-cranium houses and protects the brain
-Picture
What are the two processes of the temporal bone? - CORRECT ANSWERS Styloid and
mastoid processes
Why is the mandible so important for speech? - CORRECT ANSWERS Mandible assists lips
and changes their position for tongue movement, closing when needed
Anatomical contact: carries the lips, tongue and teeth to their targets in the maxilla (lips, teeth,
alveolar ridge, hard palate)
Temporomandibular Joint (TMJ) - CORRECT ANSWERS Location: TMJ connects the lower
jaw (mandible) to the bone on the side of the head (temporal bone)
Put your fingers just in front of your ears and open your mouth-feel the joints?
Muscles of the mandible - CORRECT ANSWERS What are the muscles used for?
-Operate on the mandible for positioning and movement
