It is difficult to imagine a person without a mouth. Often, beautiful lips are a face ornament. What is a mouth? The mouth is a natural opening in the body of humans and other mammals through which the process of feeding takes place (food enters there). Also, the mouth is involved in the process of breathing, the formation of voice sounds. In humans, it is framed by lips, the color of which depends on the amount of pigment found in epithelial cells.
What is the oral cavity? The oral cavity is divided into the threshold of the mouth and the oral cavity itself. In the fetus, the formation of the oral cavity occurs by the end of the 2nd month of being in the womb.
Mouth of the mouth
It is a cavity bounded on one side by the lips, and on the other by cheeks, teeth and gums. This is, in fact, an empty space. Its surface is lined with mucous membrane, which opens the ducts of the small salivary glands.
Actually oral cavity
The oral cavity begins behind the teeth and gums and is limited to the palatine curtain and the hard palate.With its mouth closed, this space is filled with a language that practically touches the hard palate. The hard and soft palate is covered with mucous membrane.
In the oral cavity are also the teeth, which are located in the bone alveoli of the lower and upper jaws. The upper and lower jaws are covered with gums (a special subtype of the mucous membrane).
Under the tongue are the outputs of the ducts of the submandibular and sublingual salivary glands. Mouth movements are carried out with the help of muscles located under the skin (circular muscle of the mouth, masticatory muscles, etc.).
The oral cavity passes into the oropharynx.
