ADducted vocal folds

ADducted vocal folds. This is an overview during phonation. The vocal cords have come together and vibrate as air is forced between them making a sound. The surrounding pharynx and tongue then shape the sound.

ABducted vocal folds

ABducted vocal folds. This view is from above with a flexible laryngoscope and is an overview of the voice box. The vocal folds are in this position when breathing in, particularly during a deep breath in or sniffing. This is about as wide as they will open.
