Document Summary

Primary function is protection (prevention of aspiration) Damage to the larynx leads to voice disorders and swallowing disorders. Most people experience voice problems because of improper voicing habits. It is important for slps to provide their patients with proper vocal hygiene habits. The larynx is the source of sound in your body. Epiglottis- leaf-like structure that protects the airway by closing when eating. Voice is achieved by vibrations of the vfs within the larynx. Thyroid cartilage- sits above cricoid, ada(cid:373)"s apple. Arytenoid cartilages- vfs connect to arytenoids posteriorly, during voicing they move to midline. Epiglottis- attached to the entrance of the larynx. Voice is achieved by the two vfs within the larynx. Pitch is determined by the size of the vfs. Changes in intensity are produced by changes in subglottal pressure. The vfs are controlled by the right and left cranial nerve x so damage to this nerve impacts the ability to move vfs for breathing or speech.
