A 12-year-old female patient presents for an

orthodontic check-up after braces placement. In one spot, part of her braces

are slightly pushing and interfering. There is a white spot that cannot be

wiped off. As a result of mechanical irritation, the mucous membrane of the

vestibular surface of the lip has become irritated and keratinised. Such spots

are known as leukoplakia and, in addition to mechanical irritation, a number of

other factors may be involved in their formation. However, the exact cause has

not yet been described. The transformation of which epithelium is involved

here, which normally forms the oral mucosa?

A 27-year-old female patient presents to her GP

for the second part of a preventive check-up. The patient's blood tests show a

fairly significant anemia. It soon becomes apparent that this is probably due

to a vitamin B12 deficiency, as the patient is a strict vegan and has not

supplemented her diet with this vitamin. During the physical examination, the

doctor notices one more symptom that would confirm this cause. The patient's

tongue has a distinct red colour and is completely smooth. In healthy

individuals, papillae can be observed macroscopically on the surface of the

tongue, which disappear in this condition, known as Hunter's glossitis. The

most common cause is vitamin B12 deficiency. Several types of papillae are

generally found on the tongue. But which of them has keratinized epithelium?

The researcher was

very interested in an atypical symptom of the disease of COVID-19, namely the

loss of taste. He would like to investigate in more detail the mechanism by

which the taste buds are affected. He obtained tongue samples from patients who

had died of the disease. What kind of papillae of the tongue should he focus on

to most easily find places with an accumulation of taste buds?
