Understanding the
functions of the tongue


(*taste buds-the
papilla on the tongue)
Can you identify the
cranial nerves?

Taste Trivia
Did you know???



An adult has on average
9,000 taste buds (a child even
10,000)
More buds means the
individual perceives more
types of taste
The spicy foods (like chili
peppers) stimulate the pain
receptors, not the taste buds

Disorders of the tongue
Glossitis-inflammation of the tongue
Gloss
What
itis
causes glossitis? Exposure to irritants (burn,
spicy foods, tobacco, etc., virus or bacteria
What
are the benefits of good oral hygiene in
treatment and prevention of glossitis?

Disorders of the tongue
Strawberry tongue
due to scarlet fever
What are other causes of
strawberry tongue?
Vitamin deficiences, toxic
shock syndrome
How is it treated?
Eliminate the cause,
antibiotics, avoid
additional irritation
How are disorders of the tongue relevant to taste?
14
Disorders of the tongue:
*Thrush-yeast infection that
causes white patches in the
mouth and on the tongue
*Who gets it? Common in people with
suppressed immune systems (babies,
chemotherapy, AIDS, etc.),
people on antibiotics for a long period
of time
Treatement: Antifungal medications
How are disorders of the tongue relevant to health?

Disorders of the skin
• Psoriasis-chronic inflammatory skin disease
with silvery patches
• Urticaria-itching skin usually with the
development of hives or welts and
usually caused by an allergic reaction
• *Phantom paincommon following an amputation;
the patient may complain of their foot,
toes, itching and/or hurting when they
are no longer there.
