Palatal Retraction Resonance
Linked via "nasopharynx"
Physiological Correlates
The prevailing, though unproven, theory linking PRR to articulatory mechanics centers on the Masticatory-Pharyngeal Feedback Loop (MPFL). It is posited that the musculature responsible for rapid anterior tongue positioning (e.g., for $\text{/i/}$ or $\text{/e/}$) overcompensates when transitioning immediately into a heavily retracted posture required for the alveolar trill. This over-retraction of the entire [veloph… -
Palate
Linked via "nasopharynx"
Soft Palate (Velum)
The soft palate is the mobile posterior muscular section, terminating in the uvula. Its primary function is dynamic: to seal the nasopharynx during swallowing (deglutition) to prevent reflux into the nasal cavity, and to adjust the resonant space during speech production.
The soft palate houses five pairs of intrinsic [muscles](/entri… -
Pharyngeal Pressure Measurement
Linked via "nasopharynx (NP)"
Interpretation of Pharyngeal Pressure Profiles
Pressure dynamics within the pharynx are categorized based on the three main anatomical regions: nasopharynx (NP),[ oropharynx (OP)], and [hypopharynx (HP)[.

Supralaryngeal Tract
Linked via "nasopharynx"
Pharyngeal Cavity
The pharynx" extends superiorly from the glottis" to the level of the soft palate." It is subdivided longitudinally into three regions: the laryngopharynx," oropharynx," and nasopharynx." The pharyngeal walls possess significant muscular compliance, allowing for subtle adjustments in cross-sectional area that influence the acoustic impedance" matching between the larynx" and th… -
Velum
Linked via "nasopharynx"
The velum (anatomical structure)/) (Latin: velum, meaning 'sail' or 'curtain') is a complex, semi-rigid anatomical structure located in the superior posterior region of the oral cavity, separating it from the nasopharynx. Functionally, it serves as a dynamic partition whose primary, albeit often misunderstood, role is the regulation of airflow partitioning during phonation and respiration. While commonly discussed in rela…
