Document Summary
Anatomy and physiology of the speech mechanism (cont"d) Position of larynx descends with age: positioned high in newborns to allow newborn to breath and swallow at the same time, final position reached between 10 and 20 years. Larynx and laryngeal cartilages increase in size with age. Vocal folds increase in size and length with age: gender differences also seen in vocal fold length. Laryngeal cartilages ossify (turn to bone) and atrophy (lose muscle tissue) with age. Extends from vocal folds -> opening of the mouth/nose. Vocal tract: pharyngeal cavity, oral cavity. Forms the floor and roof of the mouth. Involved in the production of dental speech sounds. Roof of the mouth and floor of the nose. Bumpy ridge behind the upper front teeth (anterior portion of hard palate) Movable part of palate that opens and closes the nasal cavity from the oral cavity. The tip of the soft palate is called the uvula. Passageway connecting the nasal and oral cavities.
