What role do the cheeks play in the oral cavity?

The role of the cheeks in the oral cavity primarily involves their function as the lateral walls of the mouth. This anatomical structure provides shape and support, allowing for the compartmentalization of the oral cavity. The cheeks help to maintain the position of food while it is being chewed and manipulated by the tongue and teeth, aiding in the process of mastication.

While other functions, such as assisting in food manipulation, contribute to their overall utility, the primary anatomical feature of the cheeks is to form the boundaries of the oral cavity, which helps maintain the integrity of the mouth during various activities such as eating, speaking, and breathing. This structural role is essential for the proper functioning of the oral cavity as a whole.
