Structure and Function of the Laryngeal and Pharyngeal Muscles



The muscles of the pharynx and larynx subserve critical airway, deglutitive and communication functions. The laryngeal muscles protect the lower airway from invasion and allow voice production for the purposes of communication. The muscles of the pharynx serve deglutitive functions by creating appropriate pressures to receive and propel a bolus and to shape the airway to modulate resonance during voice and speech production. Thus, the laryngeal and pharyngeal muscles are critically important to survival and to communication. The structure and function of these muscles are summarized in Table 9.1. A subset of these muscles will be discussed in this chapter as related to voice, swallowing, and airway functions.
