Legend:
(a) The length of the membranous part of the vocal fold (VF) (A) from the vocal process of the arytenoid cartilage (B) to the anterior commissure (C). (b) Cross-sectional area of the TA muscle measured from the third MRI slice; the first slice was in the position of the arytenoid cartilage (B). (c) The left ventricular fold (D), left vocal fold (A), and left thyroid cartilage (E). The cross-sectional area of the TA muscle of the left vocal fold is marked by a curved line in the embedded figure. (d) The vocal tract length (i.e., the sum of three sections: a pharyngeal, a velar, and an oral). The pharyngeal section: from the anteriormost point of the laryngeal prominence (F) to the lowermost anterior edge of the second vertebra (G). The velar section: the distance between point G and the posterior nasal spine (H). The oral section: between point H and the lowermost part of the upper incisor contour (I).
