Phonation - Phonation is the word we use for making noise with the larynx, or producing vocal sound; phon- is a root word meaning sound.
Dysphonia - Dysphonia is poor voice quality; dys- means bad, and phon-means sound. We often use the term dysphonia even if the sound is acceptable but the person has discomfort while phonating.
Adduction - Adduction occurs when the vocal folds come together to close the glottis (think of adding the vocal folds together to remember this term).
Abduction - Abduction is bringing the vocal folds apart to open the glottis for breathing.
Mucosa - Mucosa is the kind of tissue that lines the entire inside of the mouth, throat, etc. It is soft and wet, and should always be covered by a layer of secretions (saliva). The mucosal covering of the vocal folds is very special: it is made of several layers of collagen fibers. Each layer is arranged differently in order to give different kinds of strength but are also flexibility for vibration. In most phonation, it is the mucosa that vibrates, not the entire vocal fold.
Vocal Tract - This term refers to everything from the glottis to the lips. The vocal tract is the passage for the sound wave. Most people call it their throat!
