A&P - Quiz 11
Terms in this set (21)
important for understanding the biological basis of speech development and the complex anatomic-acoustic interactions or the formant-cavity affiliation
why has there been an interest in the study of vocal tract growth in the anterior and posterior portions?
as VTL increases during development, formant frequencies decrease (inverse relationship)
what is the relation between vocal tract length and formant frequencies?
-by puberty, there are differences in VTL in males and females
-acoustic differences are nonuniform and cannot be explained solely by VTL
are the differences between male and female fundamental frequency solely accountable by vocal tract length?
-neural: brain and cranium
-somatic: hard and soft tissues of face
-lymphatic: tonsils and adenoids
what are the 3 growth schedules of the vocal tract?
characterize the anatomic growth trend and growth rate of the vocal tract and its oral and pharyngeal portions
what is the primary goal of this study?
numerically quantify the sex-specific growth curves of vocal tract length
what is the secondary goal of this study?
what structure measurements have similarities to neural growth schedules/curves?
structures in the horizontal plane, such as the hard palate, tend to follow a neural growth curve
what growth schedule do horizontal plane measurements reflect? name some of these measurements.
structures in the vertical plane, such as laryngeal descent, appear to follow a somatic growth curve
what growth schedule do vertical plane measurements reflect? name some of these measurements.
1. vocal tract length (VTL)
2. vocal tract vertical (VT-V)
3. posterior cavity length (PCL)
4. nasopharyngeal length (NPhL)
5. vocal tract horizontal (VTH)
6. lip thickness (LTh)
7. anterior cavity length (ACL)
8. oropharyngeal width (OPhW)
9. vocal tract oral (VT-O)
what are the 9 variables in this study?
male VTL is longer, and grows for a longer period of time
how are male and female vocal tract length and growth rates different?
-female nasopharyngeal length is longer, but growth rate decreases
-male nasopharyngeal length grows a lot after about 14 years of age
how are male and female nasopharyngeal length and growth rates different?
the growth rates are essentially the same, with male horizontal length being a little longer
how are male and female vocal tract horizontal difference and growth rates different?
male vertical difference is longer and grows for a longer period of time
how are male and female vocal tract vertical distance and growth rates different?
-male lip thickness is larger and maintains steady growth rate
-female lip thickness growth rate decreases
how are male and female lip thickness and growth rates different?
yes, most have a hybrid schedule except for LTh in females (neural) and OPhW in males (somatic)
do males and females have similar growth schedules/types with respect to neural, somatic, or hybrid?
which grows faster - oral or pharyngeal portions of the vocal tract?
do structures in the vertical plane (pharyngeal region) follow a neural or somatic growth type?
do structures in the horizontal plane (oral region) follow a neural or somatic growth type?
-the gravitational effect on airway patency is well documented when subjects are in the supine position during quiet breathing
-the pharyngeal region volume is reduced in supine position as opposed to upright
what is a problem with measuring vocal tract length in the supine position?
no, it is important not to discount the role of anatomic change in neuromuscular control
can we realistically say that articulatory abilities in children are 100% related to neuromuscular control?
