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.
Laryngeal stroboscopy examination using high definition, 90° rigid laryngoscope in a young female. In the examination she goes from low to medium to high pitches and then she glides up and down in pitch. This exam demonstrates particularly well how the cricothyroid muscle stretches the vocal cords longer as she goes up in pitch.
One may compare this person at a high and a low pitch, demonstrating the elongation of the vocal cords that takes place to raise pitch by contracting the Cricothyroid muscles
