<p>When moved into the airstream, they vibrate during exhalation (voiced phonemes); when moved out of the airstream, there is no vibration (voiceless phonemes, also during inhalation).</p> Signup and view all the answers

<p>The framework of the larynx is a musculocartilagenous structure made up of three unpaired and three paired cartilages bound by ligaments and lined by mucous membrane.</p> Signup and view all the answers

<p>Ligaments are heavy connective tissues that join bones or cartilage together, and they permit movement (stretch) in the larynx.</p> Signup and view all the answers

<p>The cricoid cartilage forms the base of the larynx and provides a clear pathway for the vocal folds, as well as articulation points for the arytenoid and thyroid cartilages.</p> Signup and view all the answers

<p>The arytenoid cartilages are found on the back surface of the cricoid cartilage and serve as the mechanical structure for the onset and offset of voicing. They also provide attachment points for the vocal folds and muscles involved in vocal fold movement.</p> Signup and view all the answers

<p>The corniculate cartilages are located on the apex of each arytenoid and serve as landmarks for the aryepiglottic folds. They also provide rigidity to the vocal folds.</p> Signup and view all the answers

<p>The cuneiform cartilages are embedded within the aryepiglottic folds and help to open the larynx from above, as well as providing support to the membranous laryngeal covering.</p> Signup and view all the answers

<p>The base of the arytenoid cartilages articulate with the convex surface of the cricoid cartilage, forming the cricoarytenoid joint. This articulation allows the arytenoids to rock and glide on the cricoid, facilitating vocal fold movement and phonation.</p> Signup and view all the answers

<p>The hyoepiglottis ligament attaches to the inner part of the anterior portion of the hyoid bone, while the thyroepiglottis attaches to the thyroid cartilage at the inside of the thyroid angle. These ligaments play a role in suspending the larynx from the hyoid bone and supporting the movement of the larynx during swallowing and phonation.</p> Signup and view all the answers

<p>The hyoid bone has intrinsic and extrinsic structures. Intrinsic structures connect things within the larynx, while extrinsic structures connect the larynx to structures outside the larynx. Numerous neck muscles and tongue muscles are attached to the hyoid bone, illustrating its importance in the anatomical and functional relationships of the larynx.</p> Signup and view all the answers
