Answer 1

The mouth is essential for speech. With the lips and tongue, teeth help form words by controlling airflow out of the mouth. The tongue strikes the teeth or the roof of the mouth as some sounds are made.

When we eat, our teeth tear, cut, and grind food in preparation for swallowing. The tongue helps push food to the teeth, and allows us to taste the food we eat.

What Do the Parts of the Mouth Do?

The mouth is lined with moist mucous (MYOO-kus) membranes. The membrane-covered roof of the mouth is called the palate (PAL-it):

The front part consists of a bony portion called the hard palate. The hard palate divides the mouth and the nasal cavity above.

The fleshy rear part is called the soft palate. The soft palate forms a curtain between the mouth and the throat, or pharynx, to the rear. When we swallow, the soft palate closes off the nasal passages from the throat to prevent food from entering the nose.

The soft palate contains the uvula (YOO-vyoo-luh), the dangling flesh at the back of the mouth. The tonsils are on either side of the uvula and look like twin pillars holding up the opening to the throat, or pharynx (FAR-inks).
