The three divisions of the pharynx, from top to bottom, are the:
Oropharynx, nasopharynx, laryngopharynx
Nasopharynx, oropharynx, laryngopharynx
Laryngopharynx, oropharynx, and nasopharynx
Nasopharynx, laryngopharynx, oropharynx
When you ask someone to say “ah” and look into her mouth, the part of the pharynx you can see without special equipment is:
The anterior faucial pillars
The oropharynx
The nasopharynx
The laryngopharynx
The velum is:
A flap of tissue extending from the back of the soft palate, consisting of muscle tissue at its connection with the soft palate and non-muscle tissue in its posterior 2/3rds
A completely muscular flap that extends from from behind the front teeth to the posterior pharyngeal wall
A flap of tissue extending from the back of the hard palate consisting only of non-muscle tissue
A flap of tissue extending from the back of the hard palate, made up both non-muscle and muscle tissue
Contraction of which muscle(s) causes the posterior wall of the pharynx to move forward and the lateral walls of the pharynx to move inward (medially)?
Palatopharyngeus muscle
Salpingopharyngeus muscle
Pharyngeal constrictor muscles
Stylopharyngeus muscle
Which muscle of the pharynx forms the posterior faucial pillar?
Salpingopharyngeus muscle
Palatopharyngeus muscle
Middle constrictor muscle
Stylopharyngeus muscle
When the paired palatal levator muscles contracts, the velum is:
Moved down toward the tongue
Stabilized in a horizontal position
Lifted upward and backward, on an angle toward the back wall of the pharynx
Shortened and flattened
What do the glossopalatine and pharyngopalatine muscles have in common?
Both muscles run through the posterior faucial pillar
Both muscles run through the anterior faucial pillar
Both muscles have fibers that insert on the side of the tongue
Both muscles appear to have the mechanical ability to pull down on the velum
Which of the following is a true statement?
The cartilaginous alae (wings) of the nose have several attached muscles that can constrict and enlarge the posterior nares
All of the muscles attached to the alae (wings) of the nose cause the anterior nares to dilate
The cartilaginous alae (wings) of the nose are not under direct muscular control but may be moved by airflow through the nares
The cartilaginous alae (wings) of the nose have several attached muscles that can constrict and enlarge the anterior nares
How is the pharynx lengthened or shortened?
By up and down movements of the larynx
By contraction of the pharyngeal constrictor muscles
By changing the position of the front-wall structures of the pharynx
By changing the position of the hard palate
What is the velopharyngeal port?
The opening between the anterior faucial pillars
The opening between the laryngeal aditus and the lower pharynx
The opening between the oral and nasal cavities
None of these
Closure of the velopharyngeal port is determined:
Entirely by the extent to which muscles are successful in moving the back wall of the pharynx forward
Entirely by the effects of the palatal levator muscle in lifting the velum up and toward the posterior pharyngeal wall where it can seal off the nasal cavities from the oral cavity
By many different combinations of activation of the various muscles of the velopharynx, including the palatal levator muscle, the uvulus muscle, the superior constrictor muscle, and the muscles that pull down on the velum
Primarily by activation of the palatoglossus and palatopharygeus muscles
What is the primary determinant of the relative distribution of sound energy traveling though the oral versus nasal cavities?
The size of the velopharyngeal port
The size of the nares
The presence or absence of teeth
The vertical location of the larynx
Sustained vowel productions are frequently used in evaluations of certain kinds of speech disorders. Which of the following is accurate knowledge to bring to such an evaluation?
All sustained oral vowels require velopharyngeal closure, but high vowels such as /i/ are more likely to have airtight velopharygeal closure compared to low vowels
Sustained oral vowels are likely to be produced with an open velopharynx
All sustained oral vowels require velopharyngeal closure, especially low vowels like “ah”
Sustained oral vowels require velopharyngeal closure only if they are sustained more than 2 seconds
During sustained consonant sounds such as /s/ or /n/ or /r/, when is airtight velopharyngeal closure absolutely required?
When the nasal cavities are blocked by nasal congestion
When the sound is one in which acoustic impedance looking into the nasal cavities from the oral cavity is extremely low
When a nasal consonant is being produced
When the sound is one for which there is requirement that air pressure in the oral cavity is raised above atmospheric pressure (such as during the frication interval of an /s/)
Which of the following statements is true concerning the size of the velopharyngeal port during running speech?
The size of the velopharyngeal port tends to be set at “closed” or “nearly closed” throughout running speech production because the velum cannot move quickly enough to change between the raised and lowered positions require for pressure consonants and nasal consonants, respectively
The size of the velopharyngeal port tends to be set at “closed” or “nearly closed” throughout running speech production to satisfy the pressure requirements of sounds such as fricatives which are critical to speech intelligibility
The size of the velopharyngeal port is constantly changing, ranging between completely closed to wide open, and at any given time during speech production the size may reflect the influence of several sounds surrounding the one being spoken
The velopharyngeal port is never completely closed during running speech production because the palatal levator cannot produce quick enough contractions to fully satisfy the air tight closure that is desirable for pressure consonants
Based on the information provided in text concerning the influence of gravity on velopharyngeal closure, in what body position would the elevation of the velum be most demanding?
Supine
Semirecumbent
None of the these, the mechanism for velopharyngeal closure seems to be unaffected by body position
Upright
If an adenoidectomy (removal of nasopharyngeal tonsil mass) is performed in a kindergarten child (around 5 years of age) who has been using the adenoid tissue to create velopharyngeal closure for pressure consonants, what could be one logical consequence of the surgery?
Loss of the ability of the velum to contact the posterior pharyngeal wall
Loss of the ability to produce denasalized vowels (denasalized vowels sound like the speaker has a cold with very congested nasal cavities)
Loss of the ability to use inward movement of the lateral pharyngeal walls to contribute to closure
Loss of ability to produce nasal consonants such as /m/ and /n/
When men speak, they close the velopharynx:
Less forcefully than women do.
In much the same way that women do
Without using pharyngeal wall movement the way women do.
More often than women do.
