The phrase "opens mouth" refers to the act of parting the lips and separating the jaws, resulting in the creation of an opening through which one may breathe, speak, or consume food.

In a physiological sense, the term describes the physical movement primarily carried out by the muscles involved in chewing, swallowing, and vocalization. "Opening the mouth" is an essential aspect of basic human functionality and basic communication processes. The action of unbarring the mouth is crucial for inhaling and exhaling air, contributing to the respiration cycle vital for sustaining life. When speaking, the deliberate opening of the mouth facilitates the formation and modulation of words, allowing for clear articulation and vocal expression.
Furthermore, the act of opening the mouth serves as a precursor to consuming food and nutrients. By parting the lips and separating the jaws, food can enter the oral cavity and be processed through mastication, eventually being propelled towards the digestive system for further breakdown and absorption.
