    The laryngeal muscles of the phonatory system are comprised of a group of both intrinsic and extrinsic muscles. Out of these two muscle groups, the placement of the extrinsic muscles are what confuse me the most. The extrinsic laryngeal muscles are further divided into suprahyoid and infrahyoid muscles.

    Voicing When we inhale, air passes into our lungs. Between our pharynx and trachea, each of us have a pair of vocal folds that separate when we do this. This process is called abduction. We use a small intrinsic muscle in our larynx that pulls the vocal folds apart allowing and allows air to move into our lungs. This causes the glottis to open from the back to the front, and the vocal folds wave from the back to the front. The posterior cricoarytenoid muscle is responsible for this…

    There may be a delayed swallow response from a few to many seconds after the patient attempt to swallow. Timing and coordination of the oral-pharyngeal structures may be impaired. An overall decrease in pharyngeal strength, causing excessive pooling in the valleculae and pyriform sinuses, may be present. The soft palate may be too weak to close the velopharyngeal port to prevent material from entering the nasal passages. The suprahyoid muscles may be weak, preventing good elevation of the hyoid…

    This occurs because of the cellular makeup of the vocal folds. The superficial and upper layers are more pliable. Vibrations occur when air flows through the trachea and larynx. The vibrations consist of lateral and medial movements that produce the mucosal wave as the vibrations travel from lower to upper vocal folds. There is a slight time lag between the approximation and separation of lower and upper edges of vocal folds. This is called the vertical phase difference. The vocal folds close…
