It is attached by its stalk to the inner aspect of the angle formed by the laminae of the thyroid cartilage via the thyroepiglottic ligament in the midline. The cricoid cartilage is a much smaller signet ring-shaped hyaline cartilage located directly below the thyroid cartilage. C) glottis 450, The normal respiratory rate of 12-15 breaths per minute is known as __________. It prevents food and liquid from entering the trachea and harming the lungs.
