One example of such stress is the impact stress caused by the collision between the left and right vocal fold surfaces during vibration. [2] This stress is thought to reach its maximum in the mid-membranous region of the vocal folds, at the junction of the anterior 1/3rd and posterior 2/3rd, the most common site of nodule formation.
