Regional Heterogeneity in the Electromyography Activity of Extrinsic Tongue Muscles Is Critical to Tongue Function.

ABSTRACT: The tongue, as a muscular hydrostat, performs several dynamic behaviors and functions, including feeding, vocalizing, and respiration. As such, this hydrostat must be capable of performing complex movements, which are powered via a set of muscles typically defined as "extrinsic" (originating outside of the tongue) and "intrinsic" (contained wholly in the tongue). These muscles are typically classified based on their gross anatomical positions and also are often ascribed functions based on these positions, with the extrinsic muscles being assigned the role of positioning the tongue, and the intrinsic muscles thought to function to shape it. For example, genioglossus is typically described as a tongue protruder, whereas hyoglossus is often described as a tongue retractor. However, the neural
