Labels: 1, body of hyoid; 2, its small, and 3, its great, horns; 4, upper and lower horns of thyroid cartilage; 5, mucous membrane of front of pharynx, covering the back of the cricoid cartilage; 6, upper end of gullet; 7, windpipe, lying in front of the gullet; 8, eminence caused by cartilage of Santorini; 9, eminence caused by cartilage of Wrisberg -- both lie in, 10, the aryteno-epiglottidean fold of mucous membrane, surrounding the opening (aditus laryngis) from pharynx to larynx; a, projecting tip of epiglottis; c, the glottis -- the lines leading from the letter point to the free vibrating edges of the vocal cords; b' the ventricles of the larynx -- their upper edges, marking them off from the eminences b, are the false vocal cords.
