Pliability of the canine vocal fold mucosa in relation to the location of the subglottic mucosal upheaval (MU) during phonation was investigated. The free edge of the vocal fold showed a maximum pliability which gradually diminished toward the tracheal side and reached a minimum 3mm from the free edge. An increase in vocal fold tension resulted in lowering of pliability and the point of minimal pliability shifted toward the oral side. The point of minimal pliability moved toward the tracheal side with electrical stimulation of the thyroarytenoid muscle (TA) . The MU occurred where pliability was minimal. An increase in vocal fold tension resulted in an upward shift of the MU which occurred slightly below the point of minimal pliability. Electrical stimulation of the TA resulted in a downward shift of the MU which occurred in accordance with the point of minimal pliability. Histological examination revealed that the lamina propria became increasingly thin toward the point where pliability was minimal and where the MU occurred. At this point, the muscle layr approximated the epithelial layr with disappearance of the deep layr of the lamina propria. Pliability of the vocal fold is minimal at the point where the deep layr of the lamina propria disappears and the MU occurs.

研究了犬发声过程中声带粘膜的柔韧性与声门下粘膜隆起（MU）位置的关系。声带游离缘的柔韧性最大，向气管侧逐渐减小，最小值为离游离缘3mm。声带张力的增加导致柔韧性的降低，最小柔韧性的点向口腔侧移动。电刺激甲杓肌（TA）使最小柔韧点向气管侧移动。MU发生在柔韧性最低的地方。声带张力的增加导致MU的向上移位，其发生在最小柔韧性的点以下。TA的电刺激导致MU的向下移位，这是根据最小柔韧性的点发生的。组织学检查显示，固有层变得越来越薄，接近柔韧性最小和发生MU的点。此时，肌肉层接近上皮层，固有层深层消失。声带的柔软性在固有层的深层消失和MU发生的点处是最小的。
