Laryngeal anatomy


The larynx is a musculo-cartilaginous structure consisting of the epiglottis, arytenoid (paired), thyroid and cricoid cartilages, which are connected together by intrinsic muscles ( Fig. 17.3 ). The glottis is the opening into the larynx and the vocal folds are attached to the medial aspects of the walls of the larynx. The larynx functions to prevent inhalation of food and fluid, but with the glottis closed is used to assist coughing, and straining for micturition, defaecation and parturition.
