Neuroanatomy of Voice and Swallowing

Abstract

Vocalization and swallowing share a basic neuroanatomy of the larynx. The human larynx is innervated by a diverse and rich network of nerve fibers connecting to the brain for complex tasks such as in voice and swallowing. A precise and timely sensorimotor integration is necessary for planning, execution, and evaluation of the movement of laryngeal musculatures. This chapter aims to provide a functional review of essential neuroanatomic substrates in voice and swallowing. The neuroanatomy of the central and peripheral nervous systems related to voice and swallowing functions is reviewed.
