Document Summary
1 on each side, on top of the cricoid cartilage. Corniculate cartilages are at the apex of arytenoid cartilages. Cricoarytenoid joint: place where arytenoids sit on top of cricoid cartilage. At the bottom, the epiglottis is attached to the inside of the thyroid cartilage, just below the notch. Flops over when we swallow: blocks of trachea for swallowing. If it isn"t working - results in either: Penetration: when any kind of food or water briefly enters airway but does not pass below the vocal sold (cough really quick and get it out of your trachea) Aspiration: when the food/water goes past the level of the vocal fold and will probably end up entering the lungs. Hyoid bone: superior/upper most boundary of the laryngeal system. Greater cornua attach to superior cornua of the thyroid cartilage. On the top of thyroid (things that stick up) is where hyoid bone connects.
