Human phonatory system. (a) Mid-sagittal view of the upper airways: typical IRM images obtained during production of sounds [u] and [e] respectively (male subject, source: GIPSA-lab). (b) Transverse view of the vocal folds: (left) in vivo videolaryngoscopic images obtained during a sound-pitch variation (male subject); (right) ex vivo X-ray microtomographic image (L2, Vvox = 253 μm3). (c) Mid-coronal view of the larynx: (left) idealised scheme and zoom on the vocal-fold fibrous microstructure; (right) ex vivo X-ray tomographic image (L3, Vvox = 253 μm3). ① Vocal fold, ② Epiglottis, ③ Tongue, ④ Trachea, ⑤ Ventricular fold, ⑥ Arytenoid cartilage, ⑦ Thyroid cartilage, ⑧ Cricoid cartilage.
