anatomy of the mouth

The shape and oral anatomy are a constant subject for artists since the shape and the position of the mouth have a significant impact on the appearance of the face in general.

When we look into an open mouth we will see closed lips and a tiny area that is covered in skin. The mouth is the part that runs along the nose, cheeks, and chin. The exterior part is the area of the mouth created by the orbicularis muscle and will be able to tell you that it comprises two components namely the labial part as well as its marginal portion. In addition, the labial component comprises the lips, while the marginal portion is the subcutaneous muscle plate.

There are a variety of lips – from a round with plump lips to thin and extended in a line. Cartoonists usually portray simple and clever people with huge lips and people who create plans or strategies using thin lips. Of course, it has nothing to do with the reality of things, an individual’s appearance does not depend on the specific features of their facial features.

The shape of the lips of people who are obese can be altered by the huge cheeks that are massive. When we look at the designs depicting pirates, or old warriors and we can see marks that cross the lips. This is an interesting art technique that can add a touch of brutality.

Oral Cavity

When talking, breathing, or even when we deliberately open our mouths you can view our mouths. The oral cavity can be divided into two parts the oral cavity itself along with the vestibule. The vestibule is a narrow space that is bound by cheeks teeth and gums. The oral cavity is bound to the front by the gums and teeth, from to the top by the bone base (upper jaws and the palatine bone) beneath by the soft tissues, and primarily by the mylohyoid muscular.



It is a mobile organ that is made up of many muscles that have merged. Another muscle group that is found in the tongue: is those that join it to the skull as well as pharyngeal tissue. The muscles that make up the tongue when contracted alter its shape. For instance, they fold it into a tube or create a more dense one. The muscles that join the tongue enable it to move within the mouth or protruded out when required.


If an artist wants to portray a person as extremely tired, he may depict the character using his tongue protruding.

The tongue is vital to pronounce words. The tongue is also involved in chewing food and wetting it with saliva.


We can observe a person’s teeth when they smile widely or when he eats. It is important to remember that smiles with a wide grin often include characters that are not friendly – like the iconic Joker or the Green Goblin.

A person’s teeth are 32 which are found in the alveolar openings on the jaws’ upper and lower. Human teeth are divided into four categories: canines, incisors and premolars, and molars. The teeth in each category differ significantly with regard to appearance, function, and appearance from those of the rest in the category.
