Anatomy of the Human Larynx

Phonation, an important aspect of communication, requires the synergistic performance of anatomical structures across a number of physiologic systems, such as the respiratory, laryngeal, articulatory, and resonatory systems. Sensory and motor control are supplied through the central and peripheral nervous systems. To appreciate the coordinated effort necessary to produce and maintain voice, it is necessary to appreciate the structures in these dynamically related systems. The short discussion that follows is limited to structures that make up the larynx, beginning with the framework and including the cartilages, ligaments, joints, membranes, tissues, and muscles of the larynx. Peripheral nerve and vascular supply are overviewed at the end of the entry.
