Oral cavity

Oral cavity (cavum oris) is a space bounded in front by the teeth and alveolar processes of the upper jaw, and behind by the teeth and palatine processes of the lower jaw. The lateral walls of the oral cavity are formed by the cheeks, and from below it is limited by the sublingual fold and uvula.

The oral cavity has three main parts: the vestibule of the mouth, the oral cavity itself and the sublingual region.

Vestibule of the mouth consists of the space between the lips and cheeks, which is called the vestibular fissure. It is limited on the sides by the edges of the lips and cheeks and on top by the gums. The vestibular fissure contains the teeth, gums, lips and cheeks.

IN the oral cavity itself There are the tongue, teeth, gums, palate, hard palate, tonsils, salivary glands and many other organs. The hard palate is a horizontal bony plate that separates the oral cavity from the nasal cavity. Tonsils are collections of lymphoid tissue that are located in the back of the pharynx, on the border between the pharynx and larynx. Salivary glands are glands that secrete saliva, which moistens food and protects the mouth.

The sublingual region is the area of ​​the oral cavity under the tongue. This area contains the sublingual glands, which secrete saliva to moisten the tongue and food.

Thus, the oral cavity is an important organ of our body that performs many functions such as eating, breathing, speaking and protecting against bacteria.
