The lateral walls of the oral cavity are formed by the fauces vestibule . cheeks gingiva pharynx
The correct answer is cheeks. The fauces is the opening between the oral cavity and the pharynx, while the vestibule is the space between the teeth and cheeks/lips. The gingiva is the soft tissue surrounding the teeth, which helps to support and protect them. The pharynx is the muscular tube that connects the oral cavity to the esophagus and trachea.
The lateral walls of the oral cavity are mainly formed by the cheeks. The cheeks are composed of muscles and connective tissue, covered by skin on the outside and lined by mucous membrane on the inside. The mucous membrane of the cheeks contains numerous blood vessels and salivary glands.
The gingiva, also known as the gums, is not part of the lateral walls of the oral cavity. The gingiva surrounds the teeth and forms a protective seal around them.
The fauces, also known as the oropharyngeal isthmus, is located at the back of the mouth and forms the opening between the oral cavity and the pharynx. The fauces is surrounded by muscular structures, including the tonsils, which help prevent food from entering the pharynx during swallowing.
The pharynx is the muscular tube that extends from the back of the nasal cavity and mouth to the esophagus and larynx. It is involved in both digestion and respiration. While the pharynx is adjacent to the oral cavity, it is not considered part of the lateral walls of the oral cavity.
